摘要：

对大豆质核互作雄性不育系W931A和可育对照品种9240-25的柱头活力测定结果表明:W931A的雌蕊育性正常,其柱头活力与正常品种相仿.在延迟授知情况下,柱头活力可保持22.5天,以盛花末花期中上部的花柱头活力最强,在同一节位上授粉花数控制在12个范围内,成荚率可高达50%60%.

Abstract:

Stigma vitality of the nucleo-cytoplasmic male sterile soybean line W931A and the normal fertility soybean variety 92-40-25 were examined. The stigma fertility of W931A was found to be normal similar to that of 92-40-25. When pollination was postponed, stigma vitality was retained for 2d-2. 5 d. The stigma vitality of flowers at middle-upper position during R2-R3 was most powerful. The percentage of pod setting reached 50%-60% when no more then two pollinated flowers could be controlled at the same node.

Key words: Soybean Nucleo-cytoplasmic male sterile line Stigma vitality
