湖北光敏感核不育水稻农垦58S是在一季晚粳农垦58大田中发现并培育而成的一种新型雄性不育材料。在一定温度范围内,它的育性受一天中的光照时间长短的调控。当日照时间长于一阈值时(13.5至14小时),它的雄性器官败育,日照时间短于这阈值时,雄性器官发育正常。这一奇妙的特性可以通过短日照下自交结实遗传给子代,也可以通过长日照下与不同类型水稻杂交配制杂种或转育出新的不育系。据遗传学家分析,这一特性是由细胞核内的一对
Hubei Photo-sensitive Genic Male Sterile Rice Nongken 58S is a new type of male sterility material discovered and cultivated in the field of late japonica Nongken 58 in one season. Within a certain temperature range, its fertility is regulated by the length of light in a day. When the sunshine time is longer than a threshold (13.5 to 14 hours), its male organ is aborted, and when the sunshine time is shorter than this threshold, the male organ is normal. This marvelous trait can be passed on to the offspring through selfing in the short sunshine or by crossing with different types of rice under long sunshine or breeding new sterile lines. According to geneticists analysis, this feature is a pair of nuclei inside
