关于小麦矮生性的遗传研究,近几年已有较多的报道。一般认为株高的遗传比较简单,矮生性既受1—3对主要基因的控制,又可能存在数目不等的修饰基因,因而大都呈连续变异。一些研究还表明,和株高有关的染色体约在10条左右,而以B组染色体影响较大。一般说,高秆还是显性,F_1的表现一般为中间偏高亲,与双亲株高平均数存在着正相关关系,说明在株高的遗传中,基因
On the dwarfism of wheat genetic research, in recent years have been more reported. Generally believed that the genetic height of the plant is relatively simple, dwarfism is controlled by 1-3 pairs of major genes, there may be a number ranging from the modified gene, which showed a continuous variation. Some studies have also shown that about 10 chromosomes are related to plant height, while chromosomes in group B have a greater impact. In general, tall stalks or dominant, F_1 performance is generally high in the middle of the progeny, and parental high average there is a positive correlation, indicating that in the genetic height of the gene
