大豆杂交期间气象因子对杂交成活率影响的通径分析
Effect of Meteorological Factors on Hybrid Survival Rate during Soybean Hybriding
摘要
Abstract
Three kinds of soybean hybrid combinations with different maturity including early-mature x late-mature, similar maturity X similar maturity and late-mature X early-mature, were used in this study,each group had 10 combinations. Daily average temperature, daily average humidity, the daily precipitation, and survival rate of different cross during hybrid season were recorded and path analysis between meteorological factors and hybrid survival rate were investigated. Meteorological factors had strong effect to the success of hybrid survival rate,and this effect varied with soybean hybrid combinations. Early-mature x late-mature combinations had higher success rate under the condition of lower temperature, lower humidity and no rainfall. Similar maturity X similar maturity combinations tended to get higher success rate under a broad condition of normal daily temperature and lower humidity. However, under the condition of higher daily temperature, lower humidity and no rainfall, the combinations of late-mature x early-mature had higher success rate.关键词
