摘要: 作者在玉米对青枯病抗性鉴定的基础上,选用6个抗性不同的自交系,按完全双列杂交设计,进行了玉米对肿囊腐霉菌(Pythium inflatum Matthews )青枯病的抗性遗传研究。首次证明:玉米对肿囊腐霉菌青枯病的遗传方式因自交系而异, 有的自交系具数量性状遗传特点,有的则具质量性状遗传特点。属数量性状遗传的自交系,其抗性主要是受加性基因控制。
Abstract:Based on the identification of resistance,six inbreds with defferent degrees of resistance were used in the inheritance experiment dexigned by a complete diallel cross.Genetic study on maize resistance to Pythium inflatum Matthews was carried out.The results showed for the first time that different maize inbreds may have different genetic patterns in resistance to Pythium inflatum Matthews.Some inbreds showed characteristics of quantitative inheritance,while some inbreds showed characteristics of qualitative inheritance.Resistance based on quantitative inheritance was mainly controlled by additive genes.
