利用水稻温敏核不育系核心单株筛选时的花粉镜检结果,分段统计水稻温敏核不育系群体染色花粉率的分布,设计了染色花粉率变幅、平均染色花粉率、染色花粉率为0的株率、株率峰值及其染色花粉率区段5个指标来分析判断不育系的育性转换特性和群体育性稳定性。结果表明,该方法可以更深入了解水稻温敏核不育系的群体育性表现。
Based on the microscopic examination of pollen collected at the core of single thermo-sensitive genic male sterile line in rice, the distribution of pollen percentage in the thermo-sensitive genic male sterile lines of rice was subdivided. The variation of pollen rate, average pollen rate, The pollen rate of 0 strains, the peak of the plant rate and the staining pollen rate of 5 indicators to analyze the fertility of the male sterile line to determine the conversion characteristics and stability of the colony. The results showed that this method can better understand the population fertility performance of thermo-sensitive genic male sterile lines in rice.
