Abstract
The invention discloses a method for quickly breeding directly seeded rice varieties suitable for wheat stubble along the Huaihe region. The quick breeding method comprises the following specific steps of: S1, testing in a seeding date and observing adaptability; S2, taking a dominant sterile material as a female parent and respectively hybridizing with rice varieties to gain F1; S3, implementing mixed planting of the F1 and isolating with surrounding rice, implementing mixed pressing and pollination of pollen in a full-blossom period; S4, implementing mixed harvesting of sterile plants in the mixed group; S5, isolating and planting a first cycle of groups; S6, isolating and planting a second cycle of groups; S7, screening out new directly seeded rice varieties aggregated with multiple traits; S8, finally selecting new target strains. In the quick breeding method, the dominant sterile material is used as a hybrid medium to quickly aggregate good genes, meanwhile a molecular marker-assisted breeding technique is applied to indoor filtration so that a non-target material can be quickly obsoleted, farm workload is greatly reduced and breeding efficiency is effectively increased.
Description
Technical field
The present invention relates to rice breeding technology field, particularly relate to a kind of being suitable for along area, Huaihe River wheat stubble direct seading rice kind
Quick breeding method.
Background technology
In recent years, labor shortage and water resource lack the new demand that rice breeding person proposes applicable simple and laborsaving cultivation.
To this end, selection-breeding is suitable for the direct seading rice new varieties of yangtse-huaihe region particularly Yangze river and Huai river watershed area plantation, and taking this as an opportunity, greatly
Try hard to recommend wide wheat stubble direct-sowing dry and have important practical significance for solving labor shortage and using water wisely.Conventional miscellaneous owing to utilizing
The fight section multiple target gene cycle length of polymerization, efficiency are low, need to it is possible to out cost through years of work.
Summary of the invention
The invention aims to solve shortcoming present in prior art, and the one proposed is suitable for along area, Huaihe River wheat
The quick breeding method of stubble direct seading rice kind.
To achieve these goals, present invention employs following technical scheme:
A kind of applicable quick breeding method along area, Huaihe River wheat stubble direct seading rice kind, this is suitable for along area, Huaihe River wheat stubble direct seading rice
The quick breeding method of kind specifically comprises the following steps that
S1: it be close for selecting the shorter richness of duration from seeding to heading, wheat stubble direct seading rice kind containing character such as disease-resistant, drought-enduring, high-qualitys or material
This, carry out Sowing Time Tests and adaptability observation；
S2: with dominant sterile line material as female parent, does with them respectively and hybridizes, and gathers in the crops F1；
S3: by F1 mixed planting, and isolate with Oryza sativa L. around, powder, pollination are caught up with in full-bloom stage mixing；
S4: receiving mixed for the sterile plant in above-mentioned population mixture, it is thus achieved that the first Recurrent population, fertile plant is rejected；
S5: by the first Recurrent population isolation implant, the educated individual plant that results character is excellent, after a plantation generation, binding molecule auxiliary is educated
The technology of kind, selects disease-resistant, anti-fall, drought-enduring, the direct seading rice material of high-quality；Sterile plant is mixed to be received, and obtains the second Recurrent population；
S6: isolation implant the second Recurrent population, the educated individual plant of results merit, and it is anti-to utilize molecule assisted Selection to filter out
, disease-resistant, drought-enduring, the Direct-seeding Rice strain of high-quality；Sterile plant is mixed simultaneously receives, and obtains third round colony；
S7: the like, until filtering out the Direct-seeding Rice new varieties being polymerized multiple character, and carrying out kind along Huai Maichadaoqu
Comparative test；
S8: final election goes out target new lines, it is recommended that participate in regional testing.
Compared with prior art, the invention has the beneficial effects as follows: the present invention utilizes dominant sterile line material as hybridization matchmaker
Be situated between to come rapid polymerizing excellent genes, uses molecular mark technology to carry out lab screening simultaneously, quickly eliminates non-targeted
Material, is greatly reduced field work amount, is effectively improved breeding efficiency.Select above-mentioned target variety as early as possible, aborning
Popularization and application, contribute for agricultural produce, increasing peasant income.
