摘要
为给中熟菜心的良种选育提供理论指导,研究采用灰色关联分析法,对10份中熟菜心品种的薹重与相关农艺性状进行分析。结果表明,中熟菜心的薹重与6个主要农艺性状的关联顺序为薹粗>叶片数>最大叶长>最大叶宽>叶柄长>薹高,得出薹粗、叶片数和最大叶长是影响中熟菜心薹重的重要因素。因此,在中熟菜心高产品种的选育过程中,应优先考虑薹粗、叶片数、最大叶长等指标。
In order to provide theoretical guidance for the selection and breeding of mid-mature Chinese flowering cabbage,grey correlation analysis was used to analyze stalk weight and related agronomic traits of 10 mid-mature Chinese flowering cabbage cultivars.The results showed that six major agronomic traits related to stalk weight were in following order:stalk diameter>leaf number>maximum leaf length>maximum leaf width>petiole length>stalk weight.It was concluded that the stalk diameter,leaf number and maximum leaf length are the important factors for stalk weight of mid-mature Chinese flowering cabbage.Therefore,the stalk diameter,leaf number and maximum leaf length for mid-mature Chinese flowering cabbage breeding should be prioritized.
