摘要
根据光(温)敏雄性核不育系水稻的育性模型导出的育性转换临界温度和临界日长指标,用15个代表站1951~1988年逐日平均气温和理论日长分析了7001s、N5088s和安农s-1三不育系的育性转换日期及不育期和可育期长度的气候学特征,为二系法杂交水稻的育性转换提供一种实用分析方法,并为生产提供依据。
Using the critical temperature and daylength as indices derived from the fertility alteration model of photoperital-sensitive genic male sterile rice(PGMSR)and 1951~1988 data of daily mean temperature and theoretical daylength from 15 representative weather stations on a national basis,analysis is performed of climatological characte-istics of the fertility alteration data and the duration of the fertile and sterile periods of three male sterile lines(7001s,5088s and Annong s一1).This provides a new approach to the ananlysis of climatic basis for fertility alteration of two-lined hybrid rice and a theoretical basis for further application of sterile line crop to planting.
