甘蓝型油菜隐性上位互作核不育同型临保系选育新策略
Breeding strategy of temporary maintainer with the same genetic background as two-purpose line of recessive epistatic genic male sterility system in Brassica napus L.
摘要
Abstract
New breeding strategy of temporary maintainer with the same genetic background as two-purpose line 9012AB was proposed based on the characteristics of recessive epistatic genic male sterility system in Brassica napus L.After high temperature treatment,the sterile plants with homozygous genotype was stable,and the fertility alteration was observed on the sterile plants with heterozygous genotype and the fertile alterant plants could self with certain success.Backcross was made between sterile plants from 9012AB as recurrent parent and temporary main-tainer 204TAM as donor parent.F1 ,BC1 -2 progenies were all sterile,and similar plants to 9012AB were selected and treated continuously for 15 hours at 35℃ with light.Fertile alterant plants were then backcrossed to sterile plants from 9012AB.Selfing progeny of selected fertile alterant plants was obtained from BC3.Temporary maintai-ner 9012TAM with the same genetic background as 9012AB was developed based on the offspring of selected fertile individuals from mentioned selfing progeny.关键词
