摘　　要：本研究以宁夏枸杞、黑果枸杞及其杂种域枸杞为材料,分析了三个物种植株个体、叶片和果实性状变异情况。结果表明:宁夏枸杞的株高、东西冠幅、叶长、叶宽、果实纵径、果柄长均最高或最大,且其株型、叶片表型和果型性状平均变异系数均最小。其次是杂交带个体,其株高、冠幅、叶宽、叶形指数、果实纵径、果形指数和果柄长均处于黑果枸杞和宁夏枸杞之间,且其株型和叶片表型性状平均变异系数均最大。This study used Lycium barbarum,Lycium ruthenicum,and their hybrids as materials to analyze the variation in individual,leaf,and fruit traits of the three planted species.The results indicated that the plant height,east-west crown width,leaf length,leaf width,fruit longitudinal diameter,and fruit stem length of L.barbarum were the highest or biggest,and their average coefficient of variation in plant type,leaf phenotype,and fruit type traits were the lowest.Secondly,there were individuals in the hybrids whose plant height,crown width,leaf width,leaf shape index,fruit longitudinal diameter,fruit shape index,and fruit stem length were all between L.ruthenicum and L.barbarum,and their average coefficient of variation for plant type and leaf phenotype traits were the highest.
