一般配合力是指某一亲本品种与其他若干品种杂交后,杂种后代在某个性状上表现的平均值。用一般配合力好的品种作亲本,往往会得到好的后代,容易选出好的品种。一般配合力的好坏与品种本身性状的好坏有一定关系,即一个优良品种常常是好的亲本(配合力好),在其后代中能分离出优良类型。但也并非所有品种都是好 General combining ability refers to the average value of hybrid progeny in a trait after crossing with some other breeds. With the general good mix of varieties as parents, often get good offspring, easy to choose a good variety. The quality of the general combining ability has something to do with the traits of the cultivars themselves, that is, a good cultivar is often a good parent (good combining ability), and an excellent type can be separated from its offspring. But not all varieties are good
