| 摘 要： | 通过对4个新育成的籼型雄性不育系的生育特性与柱头活力进行系统观察，结果表明：4个新育成的不育系农艺性状优良、育性稳定，套袋无自交结实情况。其中412A柱头外露率最高达89．20％，558A、698A柱头外露率与对照II-32A相当，也都高于83％。412A的柱头活力保持时间最长且柱头活力下降较慢。通过观察研究认为，4个新不育系其各项育种指标较为完善，主要农艺性状优于II-32A，具有一定的应用价值。

| Abstract: | The characteristics of growth and development and stigma vitality of 4 new bred indica male sterile lines were observed.The results showed that 4 CMS lines all exhibited excellent agronomical characters,fertility stability and self-sterility duo to using dark envelopes.Among the 4 CMS lines,the highest stigma exsertion rate of 412A reached 89.2%,558A and 698A were the same to control II-32A and both more than 83%.The stigma vitality of 412A maintained the longest time and dropped slowly.Moreover,the ot... |
