Abstract
" foundation of conventional sorghum dominant population " of the invention, belongs to plant variety breeding technique field.The technology is by the blood relationship of conventional sorghum variety complexity, relationship, the relations such as geographical are divided into two advantage groups of simple u and v, by selecting to carry out diallel cross suitable for several improved seeds that conventional sorghum producing region is promoted, find best combination (u, v) Testers are used as, by breeder have by oneself the backbone resource of emphasis respectively with u, v hybridizes, field test and survey kind, combination of all yield less than Testers is eliminated, all offspring's yield with u mixing breeds higher than Testers reservation and be included in v groups, it is combined with the offspring of v and is included in u groups, diallel cross is carried out respectively in two groups of u and v, an optimal material is selected in each group, hybridized, create preferable kind, it is also the Testers of next round simultaneously, into next cycling.The invention main application is exactly to shorten the time of conventional Sorghum Breeding, and the conventional sorghum for selecting local urgent need early promotes mainly kind.
Description
Technical field
Patent of the present invention belongs to plant variety breeding technique field, and this method can shorten the conventional Sorghum Breeding time, can be early
The conventional sorghum for selecting local urgent need day promotes mainly kind.
Technical background
The traditional Juvenile stage one of conventional sorghum is according to geographical location, such as northeast, northwest and Asia, Europe
Continent, also with good grounds blood relationship, remote edge, near edge, also with good grounds grain color, such as the methods of red sorghum, white sorghum, these methods were both
Science is not inaccurate and complicated yet, is susceptible to close relative or nearly edge or selfing etc., therefore is difficult to select preferable kind,
This technological invention method is simple and practicable and science, i.e., material or kind (parent) is divided into two jumpbogroups, hybridization material selection in group,
Group's intermolecular hybrid selection kind.Once establishing advantage group, kind can emerge in an endless stream.
The content of the invention
Conventional sorghum variety (or material) is divided into two advantages of u and v by the present invention by formulating a new Testers
Population, in group hybridization select optimal parent, optimal parents between two groups and the preferable kind be badly in need of in selection and breeding production are normal
It advises Sorghum Breeding and one new method is provided.
The technical solution adopted by the present invention to solve the technical problems is as follows：
1. according to local sorghum variety breeding objective, as eating, feeding, special, local different type is collected
Sorghum promote mainly kind, carry out diallel cross, send out first round Testers.
2. application Testers hybridize respectively with the backbone system in breeder's hand is classified as two dominant groups of u, v.
3. a most optimum materials are selected in hybridization respectively in two dominant groups, carried out using the two materials as parent miscellaneous
It hands over, so as to create new preferable kind.
4. preferable kind is promoted and applied in production, the second wheel Testers can also be used as, are cycled into next round, excellent product
Kind emerges in an endless stream.
Description of the drawings Fig. 1 establishes schematic diagram for conventional sorghum dominant population.
Specific embodiment
The first step：Formulate Testers
1. in the best sorghum variety that the suitable current production of conventional sorghum 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 (u, v) of yield.
5th, u, v combination are Testers.
Second step：Divide group
1. with own focus shaft resource respectively with u and v mixing breeds.
2. filial generation carries out field test and surveys production, every yield is more than that Testers (u, v) are selected.
3. every offspring's yield with u mixing breeds is included in v groups higher than the material in test.
4. every offspring's yield with v mixing breeds is included in u groups higher than the material of Testers.
5. set up two groups of u and v.
3rd step：Hybridization material selection in group
1. diallel cross is carried out in couple u groups selects best combination.
2. diallel cross is carried out in couple v groups selects best combination.
4th step：New varieties are selected between group
The optimal combination of selection u groups hybridizes to obtain preferable variety popularization application with the optimal combination of v groups.
5th step：New Testers
Using preferable kind as new Testers.
6th step：Xun Huan.
Claims (2)
1. the foundation of sorghum variety dominant population, feature comprise the following steps：
The first step：Formulate Testers
1. in the best sorghum variety that the suitable current production of conventional sorghum producing region selection is promoted；
2. the kind of collection is subjected to diallel cross；
3. carrying out field test surveys production；
4. find yield best combination u, v；
5th, u, v combination are Testers；
Second step：Divide group
1. with own focus shaft resource respectively with u and v mixing breeds；
2. filial generation carries out field test and surveys production, every yield is more than Testers u, v selected；
3. every offspring's yield with u mixing breeds is included in v groups higher than the material in test；
4. every offspring's yield with v mixing breeds is included in u groups higher than the material of Testers；
5. set up two groups of u and v；
3rd step：Hybridization material selection in group
1. diallel cross is carried out in couple u groups selects best combination；
2. diallel cross is carried out in couple v groups selects best combination；
4th step：New varieties are selected between group
The optimal combination of selection u groups hybridizes to obtain preferable kind with the optimal combination of v groups；
5th step：New Testers
Using preferable kind as new Testers；
6th step：Xun Huan.
2. according to claim 1, it is divided into u and v two using Testers method, conventional sorghum variety in conventional Sorghum Breeding
A dominant population.
