北疆优质杂交棉农艺性状与产量品质相关性研究

为了选育高产、纤维品质优良和适宜新疆北疆早熟棉区种植的杂交棉新品种，并为杂交组合的亲本选配提供理论指导，选用了10个北疆优质杂交棉新品种（系），对其生育期、农艺性状、产量结构性状及纤维品质性状进行了试验研究，对若干农艺性状与产量、品质性状进行了相关性分析。结果表明：对产量影响较大的性状有果枝数、株高、单株铃数，其中果枝数与产量的正相关性达到显著程度；农艺性状与品质的相关性以负相关居多；株高与产量和品质均呈正相关，可以在一定范围内通过提高株高来同时调控产量与品质。要提高杂交棉产量，除了培育适宜的株型之外，增加果枝数、单株铃数和铃重是非常重要的途径。

Correlation Analysis on Agronomic Characters of High Quality Hybrid Cotton, Fiber Yield and Quality Characters in Northern Xinjiang

In order to breed high yield,good quality new varieties in early-mature cotton area in Beijiang,and provide theoretical guidance for selecting the parents of cross combinations,the experiments were conducted to investigate growth period,and agronomic traits,yield structure character and fiber qualities on 10 high quality varieties(strains) in northern Xinjiang.And correlations were analyzed between economical characters and other traits.The results indicated that the flowering plant,plant height and the bol...
