Seed selection method of peanut in population and variety

Abstract

The invention relates to agricultural breeding field, in particular to a peanut population variety selection method. Peanut population is obtained by female parent group hybridization with male parent group, in which female parent group is obtained through peanut parent hybridization of different aim character, male parents is chosen from homozygous strain or variety, or segregating generation of heterozygote, and F1 generation hybridize, individual plant with segregation character is produced, or after each individual plant selfing. The method includes five steps of hybridization, selfing, determination, classification and population improvement. The population variety has characters of coherence, stability, specificity, high adaptability, disease resistance and high yield.

Description

【Technical field】 [0001] The invention relates to the field of crop selection and breeding, in particular to a method for breeding peanut populations and varieties. 【Background technique】 [0002] Peanut is an important economic crop. Germplasm provides rich parental materials for peanut breeding, but the research on peanut variety resources has always been carried out independently (separated from variety selection) before 1995, and the research efforts are not strong, intermittent, There is a lack of due research on the synergy of resources, genetic laws, and application value, which has caused the contradiction between abundant resources and lagging utilization. In the selection of hybrid breeding parents, we often only pay attention to the utilization of existing excellent varieties, while ignoring the excavation of excellent traits of resources, resulting in the failure of full play of the advantages of variety resources. Second, the breeding methods are backward. So...

Germplasm provides abundant parental materials for peanut breeding, but the research on peanut variety resources has always been carried out independently (separated from variety selection) before 1995, and the research is not strong and intermittent. There is a lack of due research on the synergy of resources, genetic laws, and application value, which has resulted in the contradiction between abundant resources and lagging utilization

In the selection of hybrid breeding parents, we often only focus on the utilization of existing excellent varieties, while ignoring the excavation of the excellent traits of resources, resulting in the failure of the full use of the advantages of variety resources

Second, the breeding methods are backward

Otherwise, if you want to make a highly specialized variety, simple mixing will not be able to meet the consistency requirements of the variety

And mixed breeds may have "infringement issues" for each breed

Therefore, there are no polygenic varieties in the general sense on peanuts, and wheat has not really formed a multigenic variety for large-scale production.
