玉米自交系不同穗行杂交种与正反交杂交种产量差异研究

摘要

10 maize combinations were configurated with 4 maize inbred lines.The yields of maize comparisons were compared.The results indicated that there was no obvious difference among different ear of maize orthogonal F1,different ear of good orthogonal F1 output and back-cross hybrid yield had no significant difference.%用玉米4个自交系进行组合配制成10个组合,对各组合进行产量比较,结果表明：玉米不同穗行正交F1的产量之间没有显著差异,不同穗行正交F1的产量与反交杂交种产量也没有显著差异。
