本文通过不同的光温条件对水稻两用核不育系进行处理,结果表明:光敏型两用核不育系短光照可育,长光照不育的特性,对光长的要求有局限性,并需要一定的昼夜节奏.在诱导育性转换的作用中,暗期的作用比光期的作用更大。对部分两用核不育系进行了分类.提出了光温条件对光敏型和温敏型两用核不育系育性作用的两个基本模式;同时,讨论了两系杂交稻制种与繁殖的季节问题.
In this paper, the dual-purpose nuclear sterile lines of rice were treated by different light and temperature conditions. The results showed that the light-sensitive dual-purpose nuclear sterile lines were short-light-fertile and long-photoperiod- And requires a certain rhythm of day and night, and in the role of inducing fertility transformation, the role of dark period is greater than that of light period. Two partial nuclear male sterile lines were classified, and two basic patterns of light and temperature on the fertility of photosensitive and thermo-sensitive dual-purpose genic male sterile lines were put forward. At the same time, Season of breeding.
