利用Ｓｃ２０５３化学杂交剂对矮秆小麦品系宁矮３５的杀雄效果研究表明，在０．５～０．７ｋｇ／ｈｍ２的用量下，以穗分化进程处于雌、雄蕊原基分化至药隔形成期施药的效果最好，杀雄率为１００％。在田间每亩用Ｓｃ２０５３纯品３０ｇ，对水４０ｋｇ均匀喷雾，母本异交结实率为８２．４％，千粒重３８．２ｇ，亩产杂交种子１２７．１ｋｇ，田间套袋检查种子纯度为９５％以上。１９９４、１９９６两年度制种田平均亩产杂交种子１４４．８ｋｇ，父本１８８．８ｋｇ；扬麦１５８种子繁殖田亩产４２９ｋｇ。杂交制种比种子繁殖田每亩可增收３７．７９元，比生产商品粮增收２８８．０４元 The study on the killing effect of dwarfing wheat variety Ning-dai 35 using Sc2053 chemical hybridization agent showed that under the condition of 0.5-0.7 kg / hm2, the process of spike differentiation was at the stage of estrogen and stamen primordia differentiation to the formation of septum The best effect of pesticides, kill male rate was 100%. In the field with Sc2053 per mu pure product 30g, spray evenly on the water 40kg, female parent diploma seed set rate of 82.4%, 38.1g grain weight, yield per acre hybrid seed 127.1kg, field bagging check seed purity of 95% the above. In 1994 and 1996, the average annual output of mu produce hybrid seeds of 144.8kg, 188.8kg of male parent; Yangmai 158 seed multiplication of mu produce 429kg. Hybrid seed production per acre than seed multiplication can be increased by 37.79 yuan, an increase of 288.04 yuan more than the production of commercial grain
