摘　　要：应用灰色系统理论,对8个食用向日葵三系杂交种进行了9个主要性状与产量间的关联度分析。结果表明:主要性状对产量的关联顺序依次是:盘径>茎粗>结实率>生育期>单盘粒重>株高>粒长>百粒重>粒宽;明确了各性状因素对产量的主次关系,为选育高产食葵杂交种提供了一定的依据和选择方法。By means of grey system theory,the relationship between main characters and yield of 8 edible sunflower hybrids was analyzed.The results showed that the order of grey relational grades of main characters to yield was head diameterstem diameterbearing percentagegrowth periodgrain weight per headplant heightgrain length100-grain weightgrain width.The principal relation between the yield and main characters was defined,which provided reference for high-yielding breeding of edible sunflower hybrids.
