【Objective】The characteristics of photo-thermo reaction of Peiai64S lines collected from different sources and different years were analyzed.The change reasons of critical temperature of fertility transformation were discussed.【Method】 The self-fertility and pollen fertility of five Peiai64S lines were analyzed by different photo-thermo treatments in phytotrons.【Result】 Five lines were almost completely sterile under long day light and high temperature(14.5h/28℃),however,under the condition of 14.5h/24℃,except for two lines which kept sterile,the rests were partly fertile,especially the line 4 whose self-fertility rate and pollen fertility was as high as 9.05% and 27.83%,respectively,that was very significant different from the others.The self-fertility of Peiai64S lines collected from the same source but different years were compared and the difference was also found.【Conclusion】 The results indicated that there was a significant difference among Peiai64S lines collected from different regions and different years.The critical temperature of fertility transformation in the line 4 raised and was out of the identification standard of photoperiod and thermoperiod genic sensitive sterile line.

目的研究不同来源的5份培矮64S的育性转换光温反应特性。方法利用人工气候箱对5份培矮64S的自交结实率和花粉可育度进行研究,并分析育性转换发生变化的原因。结果在长日高温条件(14.5h/28℃)下,5份材料几乎完全不育,但在14.5h/24℃,除2份材料仍然保持较好的不育性外,其它材料都有一定的结实,其中4号材料的结实率达到9.05%,花粉可育度达到27.83%,与其它4份材料的差异达到极显著水平。另外,对历年培矮64S在气候箱内鉴定的自交结实率的结果进行分析比较,发现不同年度间繁育的培矮64S光温反应特性也存在差异。结论培矮64S表现出明显的地区间和年度间的差异。4号材料的不育起点温度发生变化,不符合不育系的光温反应鉴定标准。
