丰产性是棉花品种的属性之一,它是对一定生态条件适应程度的反应。构成品种丰产性的因素主要有结铃性、铃重、衣分、衣指、籽指等。这些性状在不同的生态条件下,对构成产量的主次作用有很大差异。本文就在江苏沿海地区生态条件下,棉花结铃性、铃重等5个性状在构成丰产性中所起的作用、地位、遗传相关关系及对提高产量的效果进行分析讨论,并就建立选择的数学模型进行初步研究,为育种工作者提供参考。
High yield is one of the attributes of cotton varieties, which is a response to the adaptability of certain ecological conditions. Constitute a variety of high yield of the main factors are bell-shaped, boll weight, clothing points, fingers, fingers and so on. Under different ecological conditions, these traits greatly differ in their primary and secondary roles in yield formation. In this paper, the ecological status of coastal areas in Jiangsu, cotton boll, boll weight and other five traits in the formation of high yield in the role played, status, genetic correlation and to improve the yield of the effect of analysis and discussion, and to establish the choice The mathematical model of the preliminary study for breeding workers to provide a reference.
