在利用太谷核不育小麦进行轮回选择的过程中,一些单位发现,早熟集团经过几轮“互交—选择”以后,其早熟性并不比最早熟的亲本早,丰产集团的产量性状有变劣趋势等等。这些问题不是由于轮回选择方法本身造成的,而是由于选择不当所致。本文仅就小麦轮选育种的选择问题谈一点不成熟的看法。一、轮回选择参与的亲本数量多,加上多次互交,后代类型极为繁多,要做到正确选择,首先必须熟悉组群的每一个亲本。不
In the process of using Taigu nuclear sterile wheat for reincarnation, some units found that after several rounds of “reciprocal selection - selection”, the early maturing group did not have earlier maturity than the earliest mature parent, and the yield traits of Fengchen Group changed Poor trend and so on. These problems are not caused by the method of choice of reincarnation itself, but because of improper choice. This article talks about the immaturity of wheat rotation selection. First, the number of reincarnation parents involved in the selection, coupled with multiple cross-fertilization, very diverse types of offspring, to be the right choice, we must first be familiar with each of the parents of the group.
