采用p=6的p(p+1)/2双列设计,研究大麦籽粒的蛋白质含量(PC)和麦胶含量(GC)的遗传,并发展了检测遗传效应和变异的统计方法。结果表明,PC和GC的遗传表达均主要由三倍体胚乳的核基因控制,没有显著的细胞质效应。PC和GC的遗传则均符合加世-显性模型,加性、显性和环境(测定)的方差估计效 和,在PC 依次为6.4608,1.2741和0.0277.在GC依次为71.5020,11.0551和2.6754。显性的方向和程度随亲本和组合而有不同,平均而言,PC是增效基因为显性,GC是增效基因为隐性。文中还分析了三倍体和二倍体模型参数的对应关系,提出改良PC和GC的育种策略。
The p (p + 1) / 2 double-row design with p = 6 was used to study the inheritance of protein content (PC) and gluten content (GC) in barley grains and the development of statistical methods to detect genetic effects and variations. The results showed that both the genetic expression of PC and GC were mainly controlled by the nuclear gene of triploid endosperm, with no significant cytoplasmic effect. The inheritance of PC and GC were in line with the Garmis-dominance model, additive, dominance and environmental (determination) of the variance estimation efficiency and in the PC followed by 6.4608,1.2741 and 0.0277. The GC followed by 71.5020, 11.0551 and 2.6754. The dominant direction and degree vary with the parent and the combination. On average, PC is a synergistic gene dominant and GC is a potentiating gene that is recessive. The correspondence between the triploid and diploid model parameters was also analyzed, and the breeding strategies for improving PC and GC were proposed.
