摘要
对昆明地区９个栽培养麦品种，１０个农艺性状遗传相关和通径分析的结果表明，在荞麦育种中，选择生育期长，其中营养生长期较长，千粒重较高，而分枝数、株粒数和单株叶面积适当的材料，容易获得高产品种，选择株粒数和生育期时要注意环境条件的影响。
Ten agronomic characters of nine buckwheat cultivars were studied by geneticcorrelation analysis and path analysis in Kunming district.Results suggested that hightyield variety be bred easily through selecting breeding materials with longer growth peri-od, especially longer vegetative period,higher thousand kernel weight,proper amount ofbranch,kernel and leaf area per plant,when amount of kernel and growth period are se-lected, environmental influence be pain attention.
