在紫花苜蓿上对根系性状的遗传研究是很少的,大概是因为对根系的观察需要很多劳动力之故。Mclntosh和Miller(1981)得出了结论:在紫花苜蓿上一般配合力是根系分枝遗传变异的最重要的来源。一般配合力和特殊配合力及其交互作用都是紫花苜蓿根系大小变异的重要原因(Chloupek,1982)。一般配合力大约占总遗传变异的60％。Chloupek(1982)用电子测量器
Genetic studies of root traits in alfalfa are rare, probably because observation of the root system requires a lot of workforce. Mclntosh and Miller (1981) concluded that the general combining ability in alfalfa is the most important source of root branching genetic variation. General combining ability, special combining ability and their interaction are the important reasons for root size variation of alfalfa (Chloupek, 1982). The general combining ability accounts for about 60% of the total genetic variation. Chloupek (1982) uses electronic measuring instruments
