本文分析小麦阶段变化与熟期的遗传关系表明:春化阶段和光照阶段短的品种,比春化阶段和光照阶段长的品种抽穗早。抽穗开花后,熟期的早晚与灌浆速度和脱水快慢差异明显可见。抽穗早不一定成熟早。熟期的遗传表现,F_1代抽穗和开花介于中间偏晚,而成熟则以同晚和超晚居多;F_2代抽穗,开花和成熟为连续变异,属数量性状遗传。从倾早到倾晚,舞穗,开花近似常态分布,而成熟期则呈负偏斜为高狭峰。小麦的早熟性为隐性遗传。控制冬春性小麦熟期性状的基因数目有两种类型:一种是一对基因的熟期遗传;另一种是多对基因的熟期遗传,已测定估算为2—3对基因。同时,也研究了抽穗期和开花期与成熟期的相关。其抽穗与开花的相关系数,6个组合中有3个组合表现极显著,γ=0.7978-0.9291;而抽穗与成熟的相关,6个组合的相关系数,γ=0.1584-0.5956,表现不显著。
The analysis of the genetic relationship between the wheat stage and the mature stage showed that the vernalization stage and the light stage were shorter than the vernalization stage and the light stage. After flowering, the difference between morning and evening ripening and filling speed and dehydration speed is obvious. Heading early may not be mature early. The genetic performance of maturity, F_1 generation between heading and flowering in the middle late, and maturity at the same night and late; F_2 generation of heading, flowering and maturation as a continuous variation, is a quantitative trait inheritance. From early to late, dance spike, flowering approximately normal distribution, while the maturity was negative skewed high peak. The precocity of wheat is recessive. There are two types of genes that control the maturity traits of winter and spring wheat: one is the maturity inheritance of one pair of genes; the other is the maturity inheritance of multiple pairs of genes, which has been estimated as 2-3 pairs of genes. At the same time, the correlation between heading date and flowering and maturity was also studied. The correlation coefficient between heading and flowering showed that the combination of three of the six combinations showed extremely significant, γ = 0.7978-0.9291. The correlation between heading and maturity, the correlation coefficient of six combinations, γ = 0.1584-0.5956, showed no significant difference.
