用核不育系（ｍｓ２／ｍｓ２）配制的４ 个杂交种与相应常规杂交种进行产量和农艺性状比较，研究ｍｓ２ 基因对杂交种产量和农艺性状的影响－ 结果表明，核不育基因ｍｓ２ 对杂交种产量无显著影响，对株高、穗位高、生育时期等农艺性状也无明显不良反应，ｍｓ２ 基因对杂交种的株高、穗位高、吐丝时期和抽雄至吐丝间隔的效应因品种不同而有差异－ The effects of ms2 gene on the yield and agronomic characters of hybrids were studied by comparing the yield and agronomic traits of 4 hybrids (ms2 / ms2) and their corresponding conventional hybrids. The results showed that ms2 There was no significant adverse effect on the yield of hybrids and the plant height, ear height, growth period and other agronomic traits. The effect of ms2 gene on the plant height, ear height, silking stage and tasselling interval Differences due to different varieties -
