【摘要】 以39份红籽瓜自交系为试材,对其植物学性状、品质性状、产量性状间进行典型相关分析。结果表明,产量性状与植物学性状间的相关最密切,其次是产量性状与品质性状间、品质性状与植物学性状间;对产量影响最大的因素是单瓜种子重、单瓜种子数,其次是千粒重、单瓜重、主蔓长、叶片数。以多个性状为目标的选择育种过程中,通过控制主蔓长和叶片数,从而提高单瓜种子重、单瓜重、种仁重和出仁率。更多还原

【Abstract】 The botany traits, quality traits, yield traits of 39 inbred lines for red-seed watermelon were analyzed by canonical correlation analysis.The results showed that the very significant correlation was between yield traits and botany traits, the significant correlation was between yield traits and quality traits and so was between quality traits and botany traits. The most important factors for yield were single-fruit seed weight and single-fruit seed number, less important factors were kilo-grain weight, single-fruit weight, length of main vine and leaf number. Single-fruit seed weight, single-fruit weight, kernel weight and producing-kernel ratio were improved by controlling the length of main vine and leaf number during the course of selecting breeding aiming at multi-trait.更多还原
