2006～2010年在河北省石家庄地区自然条件下，对小麦温敏不育系BNS进行分期播种试验，研究了其在石家庄自然生态条件下的开花习性和育性转换规律。结果表明：播期对BNS育性影响较大，随着播种期的推迟，BNS雄性育性表现为完全败育或高度不育→半不育→完全可育的育性转换规律。BNS在石家庄地区10月9日以前播种，具有稳定的不育期，在此时期制种安全可靠；在11月10日以后播种，具有稳定的可育期，并且自交结实率高，繁殖系数高。

From 2006 to 2010, flowering characteristics and fertility alteration of wheat male sterile line BNS were studied by sowing date test under the natural ecological conditions in Shijiazhuang of Hebei Province. The results indicated that the fertility alteration of BNS was affected by the sowing date. With the delay of sowing date, line BNS showed the characteristics from complete or high sterility, to semi-sterility, then normal fertility. In Shijiazhuang, when BNS was sowed before September 9th, it would be complete male sterile and could be used to produce hybrid. When it was sowed after November lOth, it would have complete normal fertility and could be used to produce seeds of male sterile line,
