摘要: 利用多性状综合杂种优势对以48-2、478和A318作父本,DB405、DB406、DB415、DB424和DB428作母本组配的15个杂交种进行了评价,选出了综合表现优于对照SAU971的两个杂交组合DB406×A318和DB424×A318。

关键词: 多性状, 综合杂种优势, 玉米

Abstract: Synthetic heterosis of 10 quantitative characters with 15 maize crosses is estimated. Two crosses, DB406×A318 and DB424×A318, are selected, and synthetic expressions of them are better than those of their contrast, SAU971.

Key words: MULTI CHARACTER, SYNTHETIC HETEROSIS, MAIZE
