Genetic Resources

To assess the genetic diversity of the most important olive cultivars used in Portugal, a base collection was established with two hundred and one accessions of eleven cultivars from the different agro-ecological-regions (AER) of olive oil production. Inter-cultivar diversity was evaluated using seven RAPD primers producing fifty-nine polymorphic markers that enable cultivar distinction. Discriminant analysis according to fruit use and AER revealed a genetic structure associated with local selection both for fruit exploitation and agro-ecological adaptation. Intra-cultivar diversity of the ancient cultivar ‘Galega’ was also investigated. Three RAPD and five ISSR primers produced ninety-three polymorphic markers upon seventy-seven accessions from five AERs. Total accession discrimination was achieved. UPGMA clustering and discriminant analysis revealed that the genetic diversity was predominantly structured according to accessions origin. The within and among AER variation revealed by AMOVA supported this genetic structure and showed a high proportion of intra-AER variability. These evidences suggest that ‘Galega’ is composed by a mixture of different genotypes adapted to local conditions, indicating that this cultivar is in an early stage of domestication and should be treated as a landrace instead of a uniform cultivar. The assessment of ‘Galega’ genetic diversity within each of the five AERs indicated the highest significant level (Hg = 6.23 at p

Sesame (Sesamum indicum L.) is one of the ancient oil crops, grown in India since over 5,000 years ago. Diversity in the Indian sesame collection (3,129 accessions), representing all eco-geographical regions, for a range of morphological and agronomic characters was studied. Wide variation in plant habit (plant height and branching pattern), pubescence of various plant parts (stem, leaf, corolla and capsule), flower colour and number of flowers per leaf axil, capsule characteristics (shape, size, number in the axil of a leaf and number of locules in a capsule), number of capsules per plant, number of seeds per capsule, mean seed weight, and yield per plant was recorded. A detailed multivariate analysis was performed on a set of 100 selected accessions representing different agro-ecological zones. The accessions were classified into 7 discrete clusters. The principal components analysis described the spatial relationship among the entities and confirmed groupings obtained through clustering. Based on the clustering pattern of 100 accessions, the entire collection was allocated to different clusters. Representation of various zones in 7 clusters gives us the opportunity to form distinct diversity groups making combined use of passport and characterisation data. These diversity groups would subsequently be used for sampling the accessions for building up a core collection of sesame, a project already operative at the NBPGR.

Random amplified polymorphic DNA markers were used to assess relatedness and genetic diversity for 15 lingonberry (Vaccinium vitis-idaea) populations. Seven primers yielding 59 polymorphic bands were used to analyse 13 populations, representing ssp. vitis-idaea from Sweden, Finland, Norway, Estonia and Russia, and two populations, representing ssp. minus from Japan and Canada. A cluster analysis and a multidimensional scaling analysis (MDS) showed similar phenetic patterns among populations, with a pronounced geographic grouping in most cases. Significant correlations were obtained between geographic and genetic distances for the entire set of populations as well as for the 13 ssp. vitis-idaea populations. Mean within-population diversity was 0.206 when estimated with Lynch and Milligan's index, and 0.431 when estimated with Shannon's index, which is in agreement with the mixed mating system reported for lingonberry. Within-population variability accounted for 68.6% of the total variance when all populations were included, and for 78.8% when only populations of ssp. vitis-idaea were analysed. Two different approaches were applied to the selection of plant material for a potential gene bank: (1) a hierarchical sampling strategy based on a cluster analysis and (2) the Maximum genetic diversity program, developed for the establishment of core collections. Random sampling was undertaken for comparisons with the selected data sets. The most diverse and representative set of lingonberry specimens was obtained when samples were selected with the Maximum diversity program.

Recent paleoecological, archaeobotanical and genetic-molecular data are used to develop a hypothesis on the where, when, how and whom of plant domestication and the origin of agriculture in west Mesoamerica, and the formation of the maize-bean-squash multicrop milpa system and agro-food system which formed the base for development of ancient complex societies in this area. It is highly likely that about 10,000 before present (BP) human groups specializing in plant gathering and small game hunting in the dry tropical forest of the Balsas-Jalisco biotic morphotectonic province began the process of plant domestication and agriculture, using fire as a tool. Sympatric distribution of the putative wild ancestral populations of maize, beans and squash indicate the extreme northwest Balsas-Jalisco region as a possible locus of domestication. Diffusion of these domesticates to the rest of Mesoamerica would have occurred via existing biological-cultural corridors. The milpa agro-food system would have been established between 7,000 and 4,400 calendar years (cal) BP. The complex food technology developed in the northwest Balsas-Jalisco region between 4,500 and 3,500 BP, much more complex than in other areas at the time, also suggests this area as the origin of the milpa agro-food system. Further archaeobotanical research is needed to confirm this hypothesis. Exploratory, collection and conservation efforts are needed in these putative source populations, as well as studies on their adaptation to climatic, edaphic and biotic factors, before they are displaced by the African grasses and pesticides forming part of the region’s growing cattle industry.

An ethnobotanical field study focused on traditional uses of medicinal plants, wild food plants, and mushrooms was conducted in 37 villages in the Gollak region of eastern Kosovo. Interviews with 66 elderly informants were conducted using standard ethnobotanical methods. The uses of 92 vascular plants and 6 mushrooms species belonging to 47 different families were recorded. Mainly infusions and decoctions were quoted as folk medicinal preparations and the most commonly quoted plant medicinal uses referred to diseases of the respiratory system, skin, and gastrointestinal tract. Comparison of the collected data with the ethnobotanical findings of previously conducted studies in the surrounding Western Balkan areas showed that, even if more than the half of Gollak’s wild botanical genera quoted as medicines used are the same in Serbia and in Northern Albania, commonalities between the actual medicinal plant applications recorded in the present study and those reported for the other areas are extremely scarce. This may confirm the richness of the bio-cultural heritage of the Western Balkan region and the urgent need to conduct cross-cultural comparative field ethnobiological studies.

The transition from hunting and gathering to agriculture had revolutionary consequences for the development of human societies. Crops such as wheat, barley, lentil, pea and chickpea played a crucial role in the establishment of complex civilizations in south west Asia. Wild emmer wheat (Triticum dicoccoides) was one of the first cereals to be domesticated in the Fertile Crescent between c. 12,000 and c. 10,000 years ago. This step provided the key for subsequent bread wheat evolution. Wild emmer is found today in the western Fertile Crescent in Jordan, Syria and Israel, the central part of southeastern Turkey and mountain areas in eastern Iraq and western Iran. In this review, we summarize issues concerning geography and domestication of wild emmer wheat based on published molecular and archaeobotanical data and on our recent findings. We suggest that modern domestic tetraploid wheats derived from wild emmer lines from southeast Turkey. However, our understanding of emmer domestication is not complete. The “dispersed-specific” domestication model proposed for einkorn might well be appropriate also for emmer.

The legume pod borer, Helicoverpa armigera (Hübn.), is one of the major constraints to chickpea production, and host plant resistance is an important component for the management of this pest. The levels of resistance in the cultivated chickpea are low to moderate, and therefore, we evaluated 17 accessions of perennial Cicer along with three cultivated chickpea genotypes for resistance to H. armigera. There was a significant reduction in both leaf feeding and larval weights when the larvae were fed on the leaves of Cicer microphyllum Benth. accessions ICC 17146, ICC 17236, ICC 17240, and ICC 17248. Relative resistance index based on leaf feeding, larval survival, and larval weight indicated that C. microphyllum accessions ICC 17146, ICC 17236, ICC 17234, ICC 17240, ICC 17243, and ICC 17248 were highly resistant to H. armigera. Under natural infestation, accessions belonging to C. microphyllum, C. canariense Santos Guerra et Lewis, and C. macracanthum M. Pop suffered a damage rating of <2.0 compared to 4.0 in C. judaicum Boiss. accession ICC 17148 (annual species) and 8.5–9.0 in the cultivated chickpeas (1 = <10% leaf area damaged, and, 9 = >80% leaf area damaged). There was considerable diversity in the accessions belonging to perennial wild species of chickpea, and these can be exploited to increase the levels and diversify the basis of resistance to H. armigera in the cultivated chickpea.

It is widely accepted that two major gene pools exist in cultivatedcommon bean, one Middle American and one Andean. Recently another gene pool,designated as North Andean and a fourth group (not considered to be adistinct gene pool) have been reported by the senior author and hiscolleagues. Many of the agronomic and seed compositional attributes of the twomajor gene pools are well known, but the seed compositional value and diseaseresistance of the North Andean gene pool has not yet been characterized. Torectify this situation, the seed compositional characters, percentage of proteinconcentrations (phaseolin, lectin and α-amylaseinhibitor), the nutrient elements (calcium, phosphorus, iron andzinc) and the disease and pest attributes (angular leaf spot,anthracnose, common bacterial blight and empoasca damage) were considered.The Middle American gene pool gave higher lectin, calcium, phosphorus, sulfurand zinc than the Andean gene pool but lower phaseolin and iron. The NorthAndean gene pool is more like the Andean gene pool for phaseolin, resistance toangular leaf spot and anthracnose from Andean pathogen isolates, but more likethe Middle American gene pool for lectin, zinc, sulfur and resistance toanthracnose from Middle American pathogen isolates. On the other hand, it hadthe highest iron concentration and was more resistant to common bacterialblight. These results indicate the potential value of this gene pool in a commonbean breeding program.

The Nagoya Protocol on Access and Benefit Sharing (ABS) provides for the rights of Indigenous people and local communities in accordance with United Nations Declaration of Rights of Indigenous People. The Parties are obliged to take legislative, administrative and technical measures to recognize, respect and support/ensure the customary laws & institutions and community protocols of Indigenous peoples and local communities (ILCs). Within the ambit of contemporary debates encompassing Indigenous peoples' right to self-determination, this paper examines the effectiveness of international law (i.e. Nagoya Protocol) to influence existing or evolving domestic laws, policies or administrative measures of Parties on access and benefit sharing. Through opinion surveys of Indigenous organizations and national authorities of CBD's Parties, the findings indicate that the space, recognition and respect created in existing or evolving domestic ABS measures for rights of Indigenous communities are too inadequate to effectively implement the statutory provisions related to customary laws & institutions and community protocols, as envisaged in Nagoya Protocol. As the bio-cultural rights of Indigenous people are key to conservation and sustainable use of biodiversity, the domestic ABS laws need reorientation to be sufficiently effective in translating the spirit of international ABS laws into domestic policies.

No evidence exists of distillation in Mexico before European contact. The Philippine people in Colima established the practice in the 16th Century to produce coconut spirits. Botanical, toponymic, archaeological, and ethnohistoric data are presented indicating that agave distillation began in Colima, in the lower Armería-Ayuquila and Coahuayana-Tuxpan river basins, using Agave angustifolia Haw. and through adaptation of the Philippine coconut spirits distillation technique. Subsequent selection and cultivation of agaves led to their domestication and diversification. This did not take place in the lower river basins, where agave populations tended to disappear. The distillation technique spread to the foothills of Colima volcanoes and from there to all of western Mexico, leading to creation of tequila and other agave spirits. Two factors aided producers in avoiding strict Colonial prohibitions and were therefore key to the diffusion and persistence of agave spirits production: (1) clandestine fermentation in sealed, underground pits carved from bedrock, a native, pre-European contact technique; and (2) small, easy-to-use Philippine-type stills that could be hidden from authorities and allowed use of a broad range of agave species.

The cultivated peanut (Arachis hypogaea L.) is an allotetraploid, with two types of genomes, classified as AA and BB, according to cytogenetic characters. Similar genomes to those of A. hypogaea are found in the wild diploid species of section Arachis, which is one of the nine Arachis sections. The wild species have resistances to pests and diseases that affect the cultivated peanut and are a potential source of genes to increase the resistance levels in peanut. The aim of this study was to analyze the genetic variability within AA and BB genome species and to evaluate how they are related to each other and to A. hypogaea, using RAPD markers. Eighty-seven polymorphic bands amplified by ten 10-mer primers were analyzed. The species were divided into two major groups, and the AA and the BB genome species were, in general, separated from each other. The results showed that high variation is available within species that have genomes similar to the AA and the BB genomes of A. hypogaea.

The aim of this Report is to address the concerns of developing countries regarding the misappropriation of genetic resources and traditional knowledge by analysing new ways to implement international law obligations upon local patent systems to impose, strengthen or broaden the disclosure obligations of patent applicants.
