Abstract
The present invention provides a kind of methods for improving soybean Recurrent population genic male sterile line natural outcrossing comprising following steps: variety selection selects the early soybean and summer soybean varieties of different growing, mixed with soybean male sterile material；It experimental field selects, selection has the mountain area level land of insect pollinator, preceding stubble kind corn, rice；Site preparation；Sowing, the step S1 soya seeds mixed are broadcasted sowing；Field management, after planting spray herbicide is closed, seedling stage not thinning, and weeds are with seeing with removing, tillage and weeding ridging, and carry out the prevention and control of plant diseases, pest control, but entire florescence, desinsection, later period did not carried out bean-pod borer prevention and treatment；Harvesting.Using technical solution of the present invention, by the summer soybean varieties collocation and male sterile material mixed planting that select the early soybean kind and different growing of different growing, by variety selection and field management method etc., the natural outcrossing of soybean male sterile material is significantly improved.
Description
Technical field
The invention belongs to agricultural technology field more particularly to a kind of raising soybean Recurrent population genic male sterile line are naturally different
The method of friendship rate.
Background technique
The problems such as hereditary basis that conventional hybridization can be solved using Recurrent selection population breeding is narrow, the technical program it is big
Beans male sterile line can be by insect pollination, the drawback for overcoming conventional breeding hereditary basis narrow, and hybrid process is simple, does not have to
Artificial hybridization, the drawbacks of avoiding low artificial pollination setting percentage, waste of manpower, material resources.The utilization of soybean male sterile gene can
Overcome the polygenic difficulty of synthetic polymeric, is that bright prospects are opened up in application of the recurrent selection in population improvement.
The florescence of soybean Genetic Sterility material is up to one month or so, and the florescence of local conventional variety is generally at 10 days or so.
Early soybean summer sowing is bloomed ahead of time, and the florescence was at 7 days or so, if early July is sowed, August just starts to bloom；If summer soybean early July
Sowing, starts to bloom, the florescence was at 10 days or so mid-August；If soybean male sterile material early July is sowed, August is just bloomed,
At the beginning of longer blooming period to September.If if all native breeds all select local summer soybean varieties or spring big in Recurrent population building
The time of beans kind, entire florescence male sterile material and ground kind flower synchronization is about 15 days or so, soybean male sterile material
Short compared with the flower synchronization time of conventional variety, the Pod Bearing Percentage of sterile plant is not high.It is badly in need of a kind of raising soybean circulation group at present
The method of male sterile line natural outcrossing in body building.
Summary of the invention
Against the above technical problems, the invention discloses a kind of raising soybean Recurrent population genic male sterile line Natural cross pollinatios
The method of rate significantly improves the natural outcrossing of soybean male sterile material by variety selection and field management method etc..
In this regard, the technical solution adopted by the present invention are as follows:
A kind of method of high soybean Recurrent population genic male sterile line natural outcrossing comprising following steps:
Step S1, variety selection select the early soybean of different growing and summer soybean varieties to be mixed, then with soybean
Male sterile material carries out mixed planting；
Step S2, experimental field selects, and selection has the mountain area level land of insect pollinator, preceding stubble kind corn, rice；
Step S3, site preparation；
Step S4, sowing, the step S1 soya seeds mixed are broadcasted sowing；
Step S5, field management, after planting spray herbicide is closed, seedling stage not thinning, and weeds carry out with seeing with removing
The prevention and control of plant diseases, pest control and tillage and weeding ridging, but it is careful not to desinsection in entire florescence, the later period carries out bean-pod borer prevention and treatment；
Step S6, harvesting.
It adopts this technical solution, selects the summer soybean varieties collocation of the early soybean kind and different growing of different growing
With male sterile material mixed planting, in order to allow soybean male sterile material can be with conventional variety at the entire florescence
Flower synchronization, and by variety selection and field management method and etc., significantly improve the natural of soybean male sterile material
Outcrossing rate.
As a further improvement of the present invention, the early soybean and summer soybean mixing material and soybean male sterile material
Weight proportion is (4.5~5.5): 1.
As a further improvement of the present invention, in step S1, the number of the early soybean and summer soybean proportion for (1~
1.5):1.Further, the number of the early soybean and summer soybean proportion is (1.1~1.35): 1.
As a further improvement of the present invention, it in step S3, after Soil tillage is raked, is opened by 40~50cm of line-spacing
Row.
As a further improvement of the present invention, in step S4, early July by the soya seeds mixed by 1.33 ten thousand plants/
The density of mu is broadcasted sowing.
As a further improvement of the present invention, in step S6, after soybean mature, the seed harvested in sterile plant in batches is carried out
Sunning.
As a further improvement of the present invention, in step S5, not desinsection of entire florescence.Not desinsection of entire florescence, is conducive to
Insect pollinator pollinates, to improve the natural outcrossing of soybean male sterile material.
In addition, carrying out mixed seeding, sterile material in Recurrent population only with early soybean and soybean male sterile material
5 pod plant below of Natural cross pollinatio pod account for 97.3%, more than 5 pods account for 2.7%.Only with summer soybean and soybean male
Sterile material carries out mixed seeding, and 5 pod plant below of Natural cross pollinatio pod of sterile material account for 90.6%, 5 in Recurrent population
More than a pod account for 9.4%.Mixed seeding is carried out using different growing early soybean, summer soybean and soybean male sterile material,
5 pod plant below of the Natural cross pollinatio pod of sterile material account for 0.00% in Recurrent population, more than 5 pods account for 100%, pod number
It is more can a pod up to more than 60.
Compared with prior art, the invention has the benefit that
It is big by the early soybean kind of selection different growing and the summer of different growing using technical solution of the present invention
Beans variety matching and male sterile material mixed planting, allow soybean male sterile material can be with conventional variety at the entire florescence
Flower synchronization；By variety selection and field management method etc., the natural outcrossing of soybean male sterile material is significantly improved.
