| 摘 要： | 分析籼稻两用核不育系 W6154S 和 W6184S 的生育特性.在3月30～6月10日期间,播期的迟早与播始天数呈线性关系,6月10日以后播种,播始天数基本稳定;这两个不育系在播始期间的活动积温与播始天数亦呈线性关系.建立了反映上述两种线性变化的回归方程.讨论了这些回归方程在确定亲本播种期时的利用.

| Abstract: | The growth-development characteristics of indica rice two-way genic malesterile(MS) line W6154S and W6184S was analysised.When the MS line was sowed in theperiod of Mar.30th-June 10th,the linear relation between sowing date and the days toheading was found;When sowed after June 10th,the days to heading was relatively stable.The relation ship between the days to heading and the actively cumulative temperature forsowing-heading duration was linear.The equations were formed to describe the linear rela-tions above and the use of these equations for indetermining the sowing date of the MS lines in seed production was discussed. |
