Abstract
" foundation of northern spring wheat dominant population " of the invention, belongs to plant variety breeding technique field.The technology is by the complicated blood relationship of northern spring wheat variety, relationship, the relation such as geographical is divided into simple two advantage groups of m and n, diallel cross is carried out by some improved seeds for selecting the suitable area of wheat to promote, find best combination (m, n) Testers are used as, by breeder have by oneself the key resource of emphasis respectively with m, n hybridizes, field test and survey kind, combination of all yield less than Testers is eliminated, it is all to be higher than the reservation of Testers with offspring's yield of m mixing breeds and be included in n group, combined with n offspring and be included in m group, diallel cross is carried out respectively in two groups of m and n, an optimal material is selected in each group, hybridized, create preferable kind, it is also the Testers of next round simultaneously, into next circulation.This invention main application is exactly to shorten the time of northern Breeding of Spring Wheat, and the wheat for selecting local urgent need early promotes mainly kind.
Description
Art
Patent of the present invention belongs to northern spring wheat variety breeding technique field, and this method can shorten the wheat breeding time, can
The conventional spring wheat for selecting local urgent need early promotes mainly kind.
Technical background
The traditional Juvenile stage one of spring wheat is according to geographical position, such as Spring Wheat In Northeast China, northwest spring wheat and Europe
, African wheat breed, also with good grounds blood relationship, such as wild, cultivation, remote edge, nearly edge, also with good grounds grain type, as long awns,
Short awns and the methods of without awns, these methods neither science is also inaccurate and complicated, close relative or nearly edge or selfing easily occurs
Deng, therefore be difficult to select preferable kind, this technological invention method is simple and easy and science, i.e., material or kind is (close
This) it is divided into two jumpbogroups, hybridize material selection, group's intermolecular hybrid selection kind in group.Once establishing advantage group, kind can emerge in an endless stream.
The content of the invention
Northern spring wheat variety (or material) is divided into m and n two is excellent by the present invention by formulating a new Testers
Gesture population, in group hybridization select optimal parent, optimal parents between two groups and the preferable kind be badly in need of in seed selection production are
The conventional Breeding of Spring Wheat in the north provides a new method.
The technical solution adopted for the present invention to solve the technical problems is as follows：
1. according to northern Breeding of Spring Wheat target and purposes, as high yield type, quality and make bread, cook dumpling needed for
Flour purposes, local applicable variety is collected, form local Dominant variety group, diallel cross is carried out in group, establish first round test
Kind.
2. hybridized respectively with the key system in Testers and wheat breeding person's hand and spring wheat is divided into m and n Liang Ge colonies.
3. hybridizing material selection in group, group's intermolecular hybrid selects preferable kind.
4. the kind of promoting mainly that preferable kind is used to substitute locality, while preferable kind can be used as the second wheel to test again
Kind, circulated with this, Testers improve constantly, and improved seeds can also emerge in an endless stream.
Embodiment
The first step：Formulate Testers
1. in the best wheat breed that the suitable current production of northern spring wheat producing region selection is promoted.
2. the kind of collection is subjected to diallel cross.
3. carrying out field test surveys production.
4. find the best combination (m, n) of yield.
5th, m, n combination are Testers.
Second step：Divide group
1. with own focus shaft resource respectively with m and n mixing breeds.
2. filial generation carries out field test and surveys production, it is selected that every yield exceedes Testers (m, n).
3. it is included in n group higher than the material in test with offspring's yield of m mixing breeds by every.
4. it is included in m group with material of the offspring's yield of n mixing breeds higher than Testers by every.
5. set up two groups of m and n.
3rd step：Hybridization material selection in group
1. diallel cross is carried out in couple m group selects best combination.
2. diallel cross is carried out in couple n group selects best combination.
4th step：New varieties are selected between group
The best of breed of selection m group and the best of breed of n group hybridize to obtain to be applied in preferable variety production.
5th step：New Testers
Testers using preferable kind as the second wheel.
6th step：Circulation.
Claims (1)
1. the method for building up of northern spring wheat dominant population, its feature comprise the following steps：
The first step：Formulate Testers
1. in the best spring wheat variety that the suitable current production of spring wheat producing region selection is promoted；
2. the kind of collection is subjected to diallel cross；
3. carrying out field test surveys production；
4. find the best combination of yield：M and n cross combination；
5. combinations thereof is Testers；
Second step：Divide group
1. with own focus shaft resource respectively with m and n mixing breeds；
2. filial generation carries out field test and surveys production, it is selected that every yield exceedes Testers；
3. it is included in another population n group with material of the offspring's yield of m mixing breeds higher than Testers by every；
4. it is included in another population m group with material of the offspring's yield of n mixing breeds higher than Testers by every；
5. set up two groups of another population m group and another population n group；
3rd step：Hybridization material selection in group
1. diallel cross is carried out in couple another population m group selects best combination；
2. diallel cross is carried out in couple another population n group selects best combination；
4th step：New varieties are selected between group
The best of breed of another population m group is selected to hybridize to obtain new Testers with the best of breed of another population n group；
5th step：New Testers
Using preferable kind as new Testers；
6th step：Circulation.
