为了研究谷子光温敏不育系A2在张家口市夏天育性转换的情况，于2012年5月3日～7月3日采取分期播种（每隔15 d播种1次，共播种5次）的方式，调查了不同播期下其套袋自交结实率和农艺性状（倒一叶面积、倒二叶面积、株高、茎粗、穗长和穗粗）的变化。结果表明：在张家口市沙岭子镇，不育系A2不同播期处理的套袋自交结实率为4．21％～7．34％，变化规律不明显，处于高度不育。张家口市沙岭子镇夏天适合进行谷子杂交制种，但适宜播期有利于促进植株生长和穗部发育，从而提高谷子杂交制种的产量。

In order to study the fertility alteration of foxtail millet PTGMS Line A2 in Zhangjiakou City in summer, the materials were sowed every 15 days from May 3 to July 3 in 2012, then the changes of the self-setting rate of bagged and agronomic traits (leaf area, plant height, stem diameter, ear length and ear diameter) at different sowing date were investigated.The results showed that the self-setting rate of PTGMS Line A2 in Shalingzi Town of Zhangjiakou City was between 4.21% to 7.34% at highly sterile, the variation was not obvious.It illustrated that the summer of Shalingzi Town was suitable for millet hybrid seed production.In addition, the suitable sowing time helped to promote growth of millet plants and development of ear, thereby improving the yield of millet hybrid seed production.
