- 摘要:
- 利用两年实验数据对166个河南大豆栽培品种的7个花器性状和3个产量性状进行典型相关性和逐步回归分析,旨在揭示花器性状对产量性状的影响,为大豆育种产量水平突破提供深层理论依据。结果显示:花器性状间相关性显著,部分花器性状与产量性状相关性显著。其中,萼片、沟槽、花瓣外露对百粒重和单株总粒重的影响较大。逐步回归表明,萼片长度、花瓣外露和花柱长度对柱头的影响很大。
- Abstract:
- The correlation and stepwise regression,using the average of two year experiment data, of seven floral characters and three yield component in one hundred and sixty-six Henan soybean cultivated variety were studied to analysis the correlation between floral characters and yield component,in order to provide the theory basis for the soybean breeding with a yield breakthrough. The results revealed that :floral characters had significant correlation at the level of 5% or 1% with each other,and so were the partial floral characters with the yield component. From that,the flower sepal,the curved sepal length and the length of the petal coming out the sepal had relatively greater influence on 100-seed weight and seed weight per plant than other floral characters.The stepwise regression analysis of other floral characters to stigma showed that the curved sepal length、the length of the petal coming out the sepal and the style length had great correlation to stigma.
