在1981—1984年间对大麦8×8双列杂交就蛋白质(％),赖氨酸(％)等籽粒品质性状作了遗传分析.结果表明,蛋白质(％)和赖氨酸(％)为加性一显性遗传性状.其中赖氨酸(％)以加性遗传为主;而蛋白质(％)存在较大的显性效应.这两个性状的F值都为正值;H_2/4H_1都显著小于0.25.平均而言,控制这两个性状的基因座位以显性等位基因为主.W_r/V_r回归分析揭示这些显性基因存在减效的趋势.这两个性状与单株粒重以及千粒重为负相关.
Genetic analysis of grain quality traits such as protein (%) and lysine (%) were performed on 8 × 8 barley crosses from 1981 to 1984. The results showed that protein (%) and lysine Sex-dominant dominant trait, in which lysine (%) is mainly additive, while protein (%) has dominant dominance. Both F values are positive Significantly less than 0.25.Generally, dominant alleles were the loci controlling these two traits.W regression regression analysis revealed that these dominant genes had a diminished tendency.These two traits correlated with grain weight per plant And 1000-grain weight is negatively correlated.
