摘　　要：为杂交桑的组合选配及栽植管理提供科学依据,采用灰色系统理论关联分析方法,对贵州主要栽植的10个桑树杂交品种的产叶量与其相关的10个主要数量性状进行关联度分析。结果表明:在10个主要数量性状中,杂交桑产叶量与米条产叶量的关联度最高,为0.7992,与新梢总长的关联度其次,为0.7948,与发芽数的关联度最小,为0.5837;各性状依次为米条产叶量>新梢总长>新梢数>三眼叶重>叶长>叶宽>单叶重>单位面积叶重>节距>发芽数,其中米条产叶量、新梢总长、新梢数、三眼叶重、叶长和叶宽6个数量性状与杂交桑产叶量的关联度均>0.7103,对杂交桑产叶量的影响较大。The correlation degree between leaf yield and ten main quantitative traits related to leaf yield of ten hybrid mulberry varieties cultivated in Guizhou is analyzed by using grey systematic theoretical correlation analysis method to provide the scientific basis for combination selection and cultivation management of hybrid mulberry.Result:The correlation degree between leaf yield of hybrid mulberry and leaf yield per 1 m branch is 0.7992(the highest)among ten main quantitative traits,followed by total new shoot length(0.7948),and the correlation degree between leaf yield and germination number is 0.5837(the lowest).The correlation degree between leaf yield of mulberry and ten main quantitative traits is leaf yield per 1 m branch>total new shoot length>new shoot number>leaf weight of growth-ended shoot>leaf length>leaf width>single leaf weight>leaf weight of unit area>internode distance>germination number.The correlation degree between leaf yield of hybrid mulberry and six quantitative traits of leaf yield per 1 m branch,total new shoot length,new shoot number,leaf weight of growth-ended shoot,leaf length and leaf width is above 0.7103,which affecting leaf yield of hybrid mulberry greatly.
