摘 要 ：两套粳稻雄性不育系(A)及其保持系(B)分别与宁恢3-2(R)杂交、回交、自交、获得两个组合的 F_1(A/R)、B_2(A//A/R)、B_2′(A//B/R)、F_2和 F_3,以花粉育性和种子育性作为恢复度指标,研究宁恢3-2育性恢复力的遗传。 结果表明,BT 六千辛 A 和 L 平壤3号 A的花粉以染败为主,在光学显微镜下不易区分分离世代植株中可育和不育花粉,
Abstract:The inheritance of fertility restoration ability of Ninghui 3-2,a restorer line for CMSin sinica rice,was studied using pollen fertility and spikelet fertility as indicators ofrestoring degree.Two sets of male sterile lines(A)and their maintainer lines(B)were crossed with Ninghui 3-2(R)respectively.
