摘　　要： 在对雷州半岛菠萝蜜种质资源进行连续2a的调查、收集基础上,对其果实性状进行简单相关分析和典型相关分析,结果表明:在简单相关分析中,果实的纵径和横径对果实内果包数量、重量具有较大的影响,而包刺密度与果实可固具有极显著正相关;在对果实外观性状和内在性状的典型相关分析中,获得了3个达极显著水平的典型相关系数,其结果表明不同的果实外观性状对不同的果实内部性状产生影响的作用不同。 Canonical correlations among fruit characteristics of Jackfruit germplasm collected from Leizhou Peninsula, South China were analyzed using SAS program. Results showed that fruit length and fruit diameter had a significant correlation with bulb number and weight, and that the density of bulb spike is highly significantly correlated with total soluble contents. Canonical correlation analysis between the fruit appearance characteristic and the internal characteristic resulted in three highly significant coefficients, showing difference in effects of various fruit appearance characteristics on various fruit internal characteristics. These results would contribute significantly to the selection and breeding of jackfruit in the future.
