选取3种熟期类型杂交组合(早熟×晚熟、相近熟期×相近熟期、晚熟×早熟)各10个,对杂交期间的日平均温度、日平均湿度、日降雨量及不同类型杂交组合成活率进行统计,并进行了通径分析。结果表明:气象因子对杂交成活率影响较大,不同气象因子对不同杂交类型影响效应不同,早熟×晚熟组合在较低温度、较小湿度、无降雨的天气下成活率较高;类似熟期亲本组合对天气要求宽泛,在常温、低湿天气下杂交成活率更高;晚熟×早熟组合在温度较高、空气湿度小、无降雨的天气具有较高的杂交成活率。
Ten hybrid combinations (early maturing × late maturing, similar maturity × similar ripening, late maturing × early maturing) were selected to study the effects of daily maturity, daily average rainfall, daily rainfall and hybrid combinations on the hybridization Rate statistics, and conducted a path analysis. The results showed that the meteorological factors had a great influence on the survival rate of hybrids, and the effects of different meteorological factors on different hybrid types were different. The precocious and late-maturing combinations had a higher survival rate under lower temperature, less humidity and no rainfall; The combination of the parents required a wide range of weather conditions and had higher survival rates under normal temperature and low humidity. Late-maturing and early-maturing combinations had higher hybridization survival rates under high temperature, low humidity and no rainfall.
