摘　　要：通过对河南省2006年春棉品种区试10个品种的产量、植株及纤维品质性状组的典型相关分析得出:选择生育期短、植株中等偏高、果枝始节低、果枝台数多的性状,不仅有利于增加株铃,提高铃重和衣分,由于棉铃的增加又能间接提高主要纤维品质,确为选育高产优质棉花新品种的有效途径。通径分析表明:对产量性状的直接选择,在选取结铃性强、株铃多的植株性状时,应防止降低铃重。The results from analyzing the typical correlation between yield, fiber quality and plant characters of 10 spring cotton varieties in the regional test in Henan province in 2006, showed that the plant characters with short growth period, middle plant height, lower first branch and more branches should be selected as the ideal breeding material for breeding new cotton varieties with high yield and quality because the plant characters with short growth period, middle plant height, lower first branch and more branches not only raises cotton bolls per plant, cotton boll weight and lint percentage, but also improves the quality of main fibers. The path analysis indicates the direct selection of yield character should pay more attention to the plant characters of strong boll-bearing, higher bolls per plant and boll weight.
