本文就二棱大麦杂种F_145个组合及其10个亲本的12个农艺性状进行了遗传分析。研究表明,在本试验中,F_1杂种优势普遍存在。各亲本在不同性状上的显、隐性效应表现不一。各性状有的以加性或显性基因控制为主,有的则基本上由这二者共同控制。平均显性度(H_1/D)~(1/2)测定表明为超显性或不完全显性。控制绝大多数性状的显、隐性等位基因数目相差不大。多数性状遗传力较高。穗数和千粒重与产量关系密切。
In this paper, 12 agronomic traits of F_145 combinations of two-rowed barley and their parents were analyzed. Studies have shown that in this experiment, F 1 heterosis is ubiquitous. The parents in different traits significant, recessive effects of different performance. Some of the traits are additive or dominant gene control, while others are basically controlled by both. The average dominance (H 1 / D) ~ (1/2) determination showed super dominance or incomplete dominance. Control of most traits significant, the number of recessive alleles or less. Heritability of most traits is high. Spike number and grain weight and yield are closely related.
