在进行小麦杂种后代的选择时,每一个育种工作者都采用自己的选择方法,即根据他的遗传学知识,采用适合于特定地区条件并被认为是正确的选择方法,这样便形成了不同的选择学派。关于组合数目多少的意见并不一致。有些人认为需要做大量复杂的组合(Borlaug,1968),另一些人则认为做少数经过认真挑选的组合更好。Hansel(1969)采用所谓的“混合杂交”法,用作花粉供体的“混合”系是通过非常认真挑选之后再给母本品
In making the choice of the progeny of the wheat hybrid, each breeder employs his own selection method, which is based on his genetic knowledge, adopts a selection method that is suitable for the particular area and is considered to be the correct one, Choose school. Opinions about the number of combinations do not agree. Some people think that a large number of complex combinations are needed (Borlaug, 1968), while others think it is better to have a handful of carefully chosen combinations. Hansel (1969) uses the so-called “hybrid hybridization” method. The “hybrid” line used as a pollen donor is obtained by very carefully selecting the parent product
