摘　　要：Genetic variability in the base population plays an important role in crop⁃breeding program.A comprehensive assessment on the quantitative signs of white lupin genotypes was performed to be included in the selection process.Two limits of the environment were applied,i.e.,dense and sparse sowing.Positive true heterosis was established in PI533704×Zuter and PI533704×Lucky801 crosses by using the traits of the weight of nodules and fresh root mass weight at both limits of the environment.In more favorable growing conditions,the number and weight of nodules,as well as fresh aboveground mass weight had greater influence on the inheritance of epistatic gene interactions.In the case of dense sowing,the dominant gene actions for the weight of seeds were found more significant.With a high coefficient of inheritance in both environments,the hybrids of PI533704×Zuter and Lucky801×PI533704 were characterized by number and weight of nodules,Zuter×PI533704 by fresh root and aboveground mass weight,and almost all hybrids by seed weight per plant.The assessment of the initial material makes it highly likely to speed up the process of creating new varieties of white lupin.
