以培矮64S作母本,配制两系杂交稻制种,常常因低温影响造成母本育性转换,产生自交结实,对F1种子埋下不可估量的质量隐患。笔者通过镜检花粉、盆栽试验、套袋测试等综合因素分析,可及早测得杂交稻种子的质量结果,为后代种子利用价值评估、减少不必要的经济损失,提供参考依据。 Pei’ai 64S was used as the female parent to prepare two-line hybrid rice seed production, which often resulted in the fertility transformation of female parent due to the influence of low temperature, resulting in selfing and fruiting, laying an immeasurable quality risk on F1 seed. Through the microscopic examination of pollen, pot test, bagging test and other comprehensive factor analysis, the quality of hybrid rice seeds can be measured as early as possible to provide reference for the evaluation of future generations seed utilization value and reduce unnecessary economic losses.
