关于植物雄性不育的遗传机理问题,国内外已有很多人研究,但尚无统一的理论性解释。本研究以高粱为对象探讨雄性不育性状的遗传规律。一、材料和方法供试材料是高粱杂交种“8475”、“W821A”、“B877”和“8311”的F_1代。将杂交种的一代植株严密套袋自交留种。次年种成F_2代。于花前套袋自交。秋后调查区内每株
There are many studies on the genetic mechanism of plant male sterility, but there is no unified theoretical explanation. In this study, sorghum as the object to explore the genetic rules of male sterility traits. MATERIALS AND METHODS Materials tested were F1 generation of sorghum hybrids “8475”, “W821A”, “B877” and “8311”. A generation of hybrids will be bagged by selfing seedlings. The following year into F_2 generations. Bagging self-inflorescence before. Autumn after investigation of each plant area
