突变体的选择与利用,在很大程度上取决于变异的分离与稳定。研究变异在各世代的表现及其整个稳定过程,对有效地选育和利用突变体具有重要的意义。过去国内外对突变体特别是大突变体,作了较多的研究。山县弘忠(1977)研究了早熟突变体的抽穗期,在γ_2—γ_3
The selection and utilization of mutants depend to a large extent on the separation and stabilization of variation. Studying the performance of mutants in all generations and their entire stabilization process is of great significance for the effective breeding and utilization of mutants. In the past at home and abroad on mutants, especially large mutants, made more research. Hiroyaka Yamazato (1977) studied the heading date of early-maturing mutants at γ_2-γ_3
