摘　　要：从亲本自身增产潜力、父母本种植比例以及玉米制种田间管理等方面,论述了提高玉米单交制种产量的各项技术措施.结果表明:培育高产、高配合力、杭性强的玉米自交系,关键是利用姊妹系,改进亲本种值比例,增加制种田母本密度.; The techniques of improving yield of single cross hybrid maize have been presented considering the parental yield potential, the proportion of paternal plants and maternal plants, and the maize field management. The conclusion is that to breed high yield ,high crossability and high resistance maize selfbred line,the key is sib line, appropriate paternal proportion and high maternal density.
