It was shown that in short - season cotton , the seven traits relating to early maturity all presented dominating additive effect while displaying dominance effects , and epistatic effects from sowing to budding , from sowing to flowering and from budding to flowering ; the early maturity traits significantly interacted with the environments 结果表明：短季棉7个早熟相关性状的遗传均以加性效应为主，同时存在着显性效应，对于播种现蕾、播种开花和现蕾开花还存在着上位性效应；短季棉各早熟性状的遗传效应与环境互作显著。
