摘要
为提高桑树材料创新、新品种选育的预见性和准确性,应用灰色系统理论分析方法,对贵州主要栽培的15个桑树品种的春季产叶量与10个主要数量性状的相互关系进行了分析。结果表明,各个性状对桑树春季产叶量的关联度大小顺序依次为生长芽率>新梢总长>米条长产叶量>新梢数>发芽率>叶长>叶宽>新梢叶重比>公斤叶片数>节距。说明,生长芽率、新梢总长、米条长产叶量、新梢数和发芽率等对桑树春季的产叶量影响较大。
The relationship between 10 main quantitative characters and leaf yield of 15 mulberry varieties in spring was studied by grey relation analysis to improve materials innovation foreseeability and accuracy of mulberry breeding.The results showed that the relationship of different quantitative characters related to leaf yield was growing bud rate〉total new shoot length〉leaf yield per meter length of shoot〉 new shoot number〉germination rate〉leaf length〉leaf width〉Ratio of shoot weight to leaf weight〉leaf number per kilogram〉nodal distance,which indicates that growing bud rate,total new shoot length,leaf yield per meter length of shoot,new shoot number and germination rate are main factors affecting mulberry leaf yield in spring.
