“普通小麦性状遗传力估测”的研究,是对小麦24个杂交组合的七个经济性状的遗传力作的估测,数据材料比较丰富,测算的性状比较可靠。虽然国内外曾有过研究与应用,但对如此之多数量杂交组合的主要性状遗传力作出较深入的研究与分析,并提出有价值的观点,这是空前的。遗传力估测虽是数量性状遗传的理论值,但它是通过大量的调查研究,指示数量性状遗传的内在规律性的。同时,也反映了在多变的环境条件下,双亲性状在传递给杂种后代的过程中与环境条件的关系。因此,本研究为小麦杂交育种的亲本选配和杂交后代选择提供了理论依据,对指导育种实践有一定的现实意义,不仅验证了遗传与育种学理论,更丰富了遗传与育种学内容,也为今后农业院校遗传与育种学教学提供了资料。
The study of heritability estimation of common wheat is based on the estimation of hereditary power of seven economic traits of 24 cross combinations in wheat. The data are abundant and the measured characters are more reliable. Although there have been researches and applications both at home and abroad, it is unprecedented to study and analyze the heritability of the major traits of so many combinations and put forward some valuable ideas. Although the heritability estimation is the theoretical value of quantitative trait inheritance, it indicates the inherent regularity of quantitative trait inheritance through a lot of investigation and research. At the same time, it also reflects the relationship between environmental conditions and parental traits in the process of transferring to offspring. Therefore, this study provides a theoretical basis for the selection of parents and crossing offspring of crossbreeding in wheat, which has certain practical significance for guiding the practice of breeding. It not only validates the theory of heredity and breeding, but also enriches the content of genetics and breeding. For the future of agricultural institutions of genetics and breeding teaching has provided information.
