油菜隐性核不育系S017A的选育与应用

摘要

以G008A等为材料,应用隐性上位互作遗传原理,育成隐性核不育系S017AB、临保系M017及恢复系,并配制出系列杂交油菜新组合在生产上应用.介绍了隐性核不育系S017A的选育经过、主要特征特性及新组合的选育.%The recessive genie male sterile lines S017A/B,maintainer line M017,and its restorer lines and their hybrids for commercial production were bred with G008A and other materials as breeding germaplasm according to the principle of interaction between recessive sterile genes and recessive epistaic genes. An introduction of the development of S017A and its series of hybrid combinations were done in this paper.
