小麦化学杀雄剂不同配方效果评价

对7种小麦化学杀雄剂配方进行综合评价。结果表明，HS4配方药害轻，杀雄效果好，小麦雄性不育率达95．5％，天然异交结实率53．9％，且品种间反应不太敏感，杀雄作用广谱。使用时期比津奥啉（SC2053）晚，可以作为小麦备用化学杀雄剂，在津奥啉错过杀雄适期时使用

A Comprehensive Evaluation on Effects of Recipes of Chemical Male Sterilaot in Wheat

7 recipes of chemical male sterilant were conducted in this experiment. The results indicated that HS4 recipe was the best one, which produced 95.5% male sterility and 53. 9% cross fertilizing rate, and whose suitable period of application is later than SC2053 - So, HS4 can be used as spare chemical male sterilan when SC2053 staggers its suitable period of application.
