2、031，2中國(guó)農(nóng)業(yè)科學(xué)院作物科學(xué)研究所，北京100081摘要：以19個(gè)綠豆品種(系)為親本，采用非完全雙列雜交試驗(yàn)設(shè)計(jì)及混合線性模型，研究綠豆主要農(nóng)藝性狀的遺傳規(guī)律及其性狀間的相互關(guān)系。結(jié)果表明，綠豆全生育日數(shù)、株高、主莖節(jié)數(shù)和百粒重均以加性效應(yīng)為主，狹義遺傳率較高且達(dá)極顯著水平；單株莢數(shù)、單株產(chǎn)量和總產(chǎn)量的加性效應(yīng)和顯性效應(yīng)均顯著或極顯著，狹義遺傳率相對(duì)較低；單莢粒數(shù)主要受顯性效應(yīng)影響，廣義遺傳率較高；播種至開(kāi)花天數(shù)與株高間存在顯著或極顯著遺傳和表型正相關(guān)；單株莢數(shù)、單莢粒數(shù)與百粒重顯著或極顯著負(fù)相關(guān)；單株莢
3、數(shù)與單株產(chǎn)量、總產(chǎn)量顯著或極顯著正相關(guān)；百粒重與單株產(chǎn)量、總產(chǎn)量相關(guān)性不大；針對(duì)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(jìn)行，而對(duì)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(jìn)行。關(guān)鍵詞：綠豆；農(nóng)藝性狀；遺傳分析；相關(guān)分析；混合線性模型InheritanceandCorrelationAnalysisofMainAgronomicTraitsinMungbean(VignaradiataL．)byMixedLinearModelsLIUChang—Youl，F(xiàn)ANBao—Jiel，CAOZhi，M
