本文在田间试验的基础上对夏大豆6种不同去雄授粉时间的杂交成活率进行统计分析,各方法及杂交成活率依次为:(1)下午去雄授粉62.5%,(2)下午去雄授粉次晨再授粉55.8%,(3)下午去雄次晨授粉48.3%,(4)下午去雄次日下午授粉45.8%,(5)下午去雄第三日晨授粉32.5%,(6)晨去雄授粉21.7%.方法间差异达显著水平. Based on the field experiments, we conducted statistical analysis on the crosses survival rate of 6 different summer male pollination dates of summer soybean. The methods and crossover survival rates were as follows: (1) 62.5% pollination in the afternoon, (2) Pollination 55.8% of pollination in the morning and then (3) pollination 48.3% in the afternoon to Xiongchen (4) 45.8% pollination in the afternoon on the next day, pollination 32.5% in the afternoon on the third day of morning (6) Male pollination 21.7% .There was a significant difference between the methods.
