Analysis on S Alleles of Self-incompatible Lines in Eruca sativa Mill
摘要
Abstract
[Objective] In the process of operating breeding research by ways of self-incompatible lines in E. Saliva Mill. , seed setting percentage from the cross of two parents was high in bud stage, but the number of seeds was low in flowering stage owing to the natural segregation. This paper aimed to avoid this problem occurring in obtaining good combination by artificial trial after trial. [ Method] By using methods of complete diallel crossing, the purity of 5 alleles in 11 self-incompatible lines of Yunjie was studied. [ Result] Results showed that the self-compatible index of 9 materials 7-5-1-1,7-5-1-2,Yunjie SI-1.Hetian YunjieI,87-86I,Dingxi Yunjiel,Weiyun-7I,87-85I,9421I after selfing and crossing among different plants from the same lines was below 1, and belonged to self-compatibility, which suggested that S alleles of 9 materials were homozygous and the self-incompatibility were stable There were 6 S allele genotypes among 9 materials. The self-incompatibility both 06 Wuyun 3 and Machang Yunjie were not stable. [Conclusion] Thus, while creating F, hybrids using self-incompatible lines, it was necessary for us to determinate further purity of S alleles and genotype of self-incompatible lines besides basic stability agronomic traits and self-incompatibility, which could be used effectively in breeding practice.关键词
