摘  要:
以7个胭脂萝卜品种为试材,采用多元回归和通径分析方法分析了主要农艺性状对肉质根色素产量的影响。结果表明,株高、叶重、根外露长对肉质根色素产量影响显著,对肉质根色素产量影响顺序为株高>根外露长>叶重。据此建议色素高产育种应在株高较矮和根外露较短的基础上,选择叶较少的品种。

摘  要:
7 rouge radish varieties were used to analyze effect of agronomic characters on pigment yield of f lesh root with multiple regression and path analyses. The results showed that plant height, leaf fresh weight and outside root length had prominent effects on pigment yield of f lesh root. The trait that contributes the most to pigment yield of f lesh root was plant height, then outside root length, then leaf fresh weight.High pigment yield breeding should select the varieties with less leaf on the basis of reducing plant height and outside root length.
