摘要/Abstract

摘要：

【目的】研究棉花单株产量与主要农艺性状之间的关系,为丰富棉花育种的基础材料和培育优良杂交种提供依据。【方法】以陆地棉徐州142和系9的正反交组配合衍生的90和78份F_2∶3家系,采用相关性分析、主成分分析、回归分析和通径分析等方法,研究组合的株高、果枝数、有效果枝数、铃数、有效铃数、单铃重和衣分等指标和棉花单株皮棉产量的关系。【结果】F_2∶3家系具有丰富的变异,大部分性状表现出典型数量遗传特点,普遍存在超亲分离现象,各个性状的杂种优势表现明显。单株籽棉产量和单株皮棉产量与株高、果枝数、有效果枝数、铃数、有效铃数和单铃重间均呈极显著正相关。提取了两类主成分,PC₁代表棉铃生长因子;PC₂代表衣分和铃重综合选择因子。有效铃数直接通径系数最大,对棉花单株产量贡献最大。【结论】有效铃数对棉花产量贡献最大,选择有效铃数多的棉花品种是高产品种选育重要途径,但也要考虑单铃重、衣分和有效果枝数,有利于培育棉花新杂交系。

Abstract:

【Objective】 To explore the relationship between yield per plant and main agronomic characters of cotton. Which is of great significance for enriching basic materials of cotton breeding and breeding excellent hybrids. 【Methods】 90 and 78 F_2∶3 families derived from Xuzhou 142 and Line 9 were analyzed by correlation analysis,principal component analysis,regression analysis and path analysis. Then the relationship between the plant height,the number of fruit branches,the number of effective fruit branches,the number of bolls,the number of effective bolls,the weight of single boll and the coat fraction of each cotton plant was analyzed. 【Results】 Phenotypic analysis showed that F_2∶3 families had abundant variation,most of the characters showed typical quantitative genetic characteristics,and there was widespread hyperparental separation,and the heterosis of each character was obvious. There were significant positive correlations between seed cotton yield per plant and lint yield per plant and plant height,number of fruit branches,number of effective fruit branches,number of bolls,and number of effective bolls and weight of single boll. Two kinds of principal components were extracted by principal component analysis,PC₁ represented cotton boll growth factors and PC₂ represented the comprehensive selection factor of lint fraction and boll weight. The direct path coefficient of effective boll number was the largest,which contributed the most to the yield per plant. 【Conclusion】 The results showed that the effective boll number contribut the most to cotton yield,and selecting cotton with more effective boll number is an important way to breed high-yielding varieties. At the same time,the weight of single boll,the lint percentage and the number of effective fruit branches should also be considered. The finding of this study is beneficial to the breeding of new hybrid lines of cotton in different directions.
