摘要
以农垦 5 8S为母本、培矮 64为父本 ,通过杂交和回交选育成的培矮 64S ,于 1991年 9月通过湖南省鉴定。培矮 64S具有导致不育临界温度低的特点 ,在长日条件下为 2 3 .8℃ ,短日条件下为 2 3 .3℃。它育性稳定、亲和性强、配合力好、适应性广 。
Pei'ai 64S was developed by crossing Nong Ken 58S as female parent to Pei'ai 64S as male parent and backcrossing. In september, 1991, it was approved in the provincal appraisial in Hunan. Pei'ai 64S is characterized by that its sterility, is induced by low critical temperature, namely, 23.8℃ under long day condition and 23.3℃ under short day condition. Having stable featility, strong compatibility, good combining ability and wide adaptability, Pei'ai 64S is a promising dual purpose sterile line.
