摘　　要：采用变异分析、偏相关分析、相关分析和通径分析等方法,对25份绿豆品种在春播条件下各主要性状与产量间的关系进行了分析。结果表明,品种间单株荚数的变异系数最大,为29.7%,单荚粒数变异系数最小,为6.9%;生育天数、株高、主茎节数、主茎分枝数、单株荚数、单荚粒数和百粒重共同影响了公顷产量93.4%的变异,产量与主茎节数和单株荚数表现出极显著相关,偏相关系数分别为-0.4526和0.4856,与单荚粒数和百粒重表现出显著相关,偏相关系数分别为0.3718和0.4232;单株荚数与产量呈极显著正相关,相关系数0.6816,单荚粒数和百粒重与产量呈显著正相关,相关系数分别为0.4160和0.3983;株高、主茎分枝数、单株荚数、单荚粒数、百粒重对产量有正直接效应,生育天数和主茎节数对产量有负直接效应。结合性状间的相互关系,在田间筛选和品种选育时,应首先考虑单株荚数、单荚粒数和百粒重,辅以株高和荚长。本研究为春播区高产绿豆品种的选育提供了参考依据。The relationship between main characters and yield of 25 mung bean varieties under spring sowing condi⁃tion was analyzed by means of variance analysis,partial correlation analysis,correlation analysis and path analysis.Pods per plant had the maximum CV(29.7%),and seeds per pod had the minimum CV(6.9%).7 agronomic traits af⁃fected 93.4%variation of yield,the correlation between yield and node number on main stem,pods per plant were extremely significantly positive.The partial correlation coefficients were-0.4526 and 0.4856,respectively.The cor⁃relation between yield and seeds per pod,100-seed weight were extremely significantly positive,the partial correla⁃tion coefficients were 0.3718 and 0.4232.There was a highly significant positive correlation between pods per plant and yield(0.6816);the correlation between branch number,100-seed weight and yield was significantly positive(0.4160,0.3983).In combination with the relationship between the characters,the number of pods per plant,the number of seeds per pod and the weight of 100 seeds should be considered first in the field screening and variety se⁃lection,supplemented by plant height and pod length.
