[目的]对杂交棉主要农艺性状与产量品质进行相关分析。[方法]对13个杂交抗虫棉的生育期、主要农艺性状、产量构成因素及产量品质的差异进行比较以及主要农艺性状、产量构成因素与产量品质进行相关性分析。[结果]各参试品种的生育期在123d左右,在整个生育期生长势较强;皮棉产量与第一果枝节位、株高、株果枝数、株铃数、总铃数和籽棉产量都呈极显著正相关,第一果枝节位与马克隆值呈显著正相关;科杂1号和春杂棉1号马克隆值最优,均为4.5;各品种的比强度在27～30cN/tex之间,差异较大;品种间皮棉产量间的差异达极显著水平。[结论]该研究为杂交棉的优质高产栽培提供了理论参考。
[Objective] The research aimed to analyze the main agronomic characters and yield and quality of hybrid cotton. [Method] The differences of growth period, main agronomic traits, yield components and yield and quality of 13 hybrid cotton cultivars were compared, and the main agronomic traits, yield components and yield and quality were compared. [Result] The growth period of each tested variety was around 123 days, and grew vigorously throughout the growth period. The lint yield and the first fruit branch, plant height, fruit branch number, boll number, boll number and seed cotton yield all showed The results showed that there was a significant positive correlation between the first fruit branch and micronaire value, the best value for Ke-Qiu-1 and Chun-qianmian-1 was 4.5, and the specific intensity was 27-30cN / tex Between the differences between the varieties of lint yield reached a significant level. [Conclusion] The study provided a theoretical reference for the high yield and high quality cultivation of hybrid cotton.
