3、與單株產(chǎn)量、總產(chǎn)量相關性不大；針對全生育日數(shù)、株高、主莖節(jié)數(shù)和百粒重的選擇可在早期世代進行，而對產(chǎn)量的選擇可以根據(jù)單株莢數(shù)和單株產(chǎn)量在晚期世代進行。關鍵詞：綠豆；農(nóng)藝性狀；遺傳分析；相關分析；}昆合線性模型InheritanceandCorrelationAnalysisofMainAgronomicTraitsinMungbean(VignaradiataL．)byMixedLinearModelsLIUChangYou，F(xiàn)ANBao．Jie，CAOZhi．Min，WANGYan，ZHANGZhi—Xiao，SUQiu
