摘要: 1990~1991年在保定地区自然条件下,利用6个中熟的陆地棉现代品种(系)进行了吐絮进程与产量及纤维品质性状关系的研究。结果表明,吐絮进程是一个稳定的性状;它与产量性状相关不显著;与纤维比强度、马克隆值和纤维长度存在着显著或极显著的负相关关系,相关系数分别为-0.9641、-0.9053和-0.9421;与纤维伸长率和整齐度相关不显著;在产量因素中,单株结铃数对皮棉产量的直接贡献最大。这一结果提示出,通过田间直接选择单株结铃数高且吐絮进程稳定的类型,可使皮棉产量和纤维品质得到同步选择和提高,这为培育高产优质陆地棉新品种(系)提供了一种有效的选择途径。

Abstract: Six current upland cotton cultivars were used to study the relationship between speedof boll opening and yield characters,and fiber traits.The results indicated thatthe speed of boll opening was a stable trait there was not statistical significance of correlation coefficient between speed of boll opening and any yield character the negative correlation coefficient wasstatistically significant or highly significant between speed of boll opening and HVI strength,andfiber length,and micronaireand bolls per plant played the most important role in lint yield.It's benefit to breed cotton varieties with both higher Lint yield and better fiber quality based onsynchronous selection of both more boils per plant and stable speed of boll opening.

Key words: Upland cotton, Speed of boll opening, Lint yield, Fiber quality, Synchronous selection
