萝卜肉质根产量与主要性状相关及通径分析

试验运用相关及通径分析,对萝卜杂交组合的株高、展开度、外露长、叶重、叶片长、叶片宽、叶片数、根长、根粗9个相关农艺性状与肉质根产量进行了分析。结果表明,萝卜杂交组合单根重与其相关性状的直接通径系数是：株高-0.3176、展开度0.3338、外露长0.7369、叶重-0.1175、叶片数0.0626、叶片宽-0.1773、叶片长0.0267、根长0.4839、根粗0.4420。外露长〉根长〉叶重〉株高〉展开度〉根粗〉叶片长〉叶柄长〉叶片数〉叶片宽〉叶柄宽。

Genetic Correlation and Path Analysis of Major Agronomic Characters of Radish

By means of Genetic Correlation and Path Analysis, the association analysis was made between the root weight and 9 relevant agronomic characters (plant height, angular divergence, leaf number, leaf weight, leaf length, leaf width, root length, root diameter and outside root length) in radish crosses. The results showed that the association grade between the fleshy root yield and main characters was as follows: plant height 0.7360, angular divergence 0.7041, leaf number 0.7259, leaf weight 0.6875, leaf lengt...
