| 摘 要： | 通过对山东省70～80年代早熟夏玉米高产杂交种主要农艺性状的分析,认为高产杂交种产量潜力的增加主要是由于提高了籽粒的千粒重,增强了品种的抗病性和因株型紧凑而增加了密度,其次是增加了穗长和穗粒数,但与穗行数无关。今后,早熟玉米育种应以大粒、抗病和紧凑株型为主要目标。

| Abstract: | Acording to several main agronomic characters analysis for early ripening summer corn with high yield in Shandong from 1970 to 1980,it indicated that:the increase of the thousand-grain weight,the improve of the varities' resistance and the compact plant are the main reasons for the increase of high yield's potency,The secodary is the increase of the spica's length and it's kernel number.But has no concern with the number of rows per ear.So the big kernal,the diseade-resistance and the compact plant are the main target for the breding of the early ripening summer corn in the future. |
