摘要
甘蓝型油菜自交系“3529”的种子经快中子及化学诱变剂硫酸二乙酯(DES)等联合处理后,其后代中出现了幼苗黄化突变体,自交纯化得到幼苗黄化突变株系T_1。遗传研究表明,这种幼苗黄化性状受一对隐性核基因控制。该性状易于转育,可作为指示性状用于油莱杂交种种子的纯度鉴定。
A yellow seedling mutant Tt was derived from the progenyof the inbred 3529(B. napus L. ) which seeds were jointly treated withfast neutro exposure and chemical inducer of DES. Genetics investigationshowed that the yellow seedling character is controlled by one pair of re-cesslve nuclear genes. The mutation character is easily to be introducedinto the other rapeseed lines and could be used as a marker character toidentify the authenticity of hybrid seeds.
