本文是应用多元回归分析方法,研究两个棉花有限总体的三个产量结构模式。分析结果表明,这三个模式是符合棉花本身实际情况的;在构成产量的诸因素中,以铃数所起的作用最大,其次为单铃重和衣份率;在高产育种工作中,应把选择重点放在铃数上,但由于铃数、铃重和衣份率之间存在着明显的负相关关系,故对铃数的选择必须有适当尺度,至于对铃数进行有效选择的直接或间接指标,尚需研究。
This article uses multiple regression analysis method to study the three yield structure patterns of two cotton limited population. The results showed that the three patterns were in line with the actual situation of cotton itself. Among the factors that constitute the yield, the boll number played the most important role, followed by the boll weight and the percentage of the clothes. In the high-yielding breeding work, The choice focuses on the number of bells, but because of the number of bells, bell weight and clothing, there is a clear negative correlation between the rate, so the choice of the number of bells must have an appropriate standard, as the effective selection of the number of bells directly Or indirect indicators, yet to be studied.
