摘要
在武汉气候条件下,对陕2A细胞质雄性不育系的不育稳定性进行了观察研究,结果表明用陕2B保持的陕ZA不育系的不育性受环境条件——温度的影响。用国内外单、双低品种(系)广泛测交,筛选到3份较好的单、双低保持材料,2份较好的单、双低恢复材料。1989年实现双低三系配套,选育出双低杂交组合7208。
The sterile stability of Shan 2A CMS was studied in Wuhan. The result showed that it was influenced by climate environment-temperature. Three better single or double low maintenance lines and two better single or double low restoring lines have be bred out by a lot of testcross for screen. In 1989 a line '7208' in double low had be bred out.
