| 为了筛选籽用茶树的特异资源，以13个高结实率茶树种质资源为材料，对茶叶籽的经济性状、品质性状及脂肪酸组成进行对比分析，并采用相关性分析、聚类分析和主成分分析对茶叶籽的性状进行综合评估。结果表明：不同品种茶树的茶叶籽单株产量、直径、百粒质量、仁壳比、脂肪含量、蛋白质含量、淀粉含量等均存在差异；茶叶籽中共检测出20种脂肪酸，饱和脂肪酸含量为12.09~33.63 g/kg，单不饱和脂肪酸含量为56.70~138.08 g/kg，多不饱和脂肪酸含量为13.09~57.17 g/kg；相关性分析表明，茶叶籽性状指标之间具有一定相关性，脂肪酸含量之间存在极显著相关性；通过层次聚类分析将13个品种茶叶籽分为三类，第一类脂肪酸含量高，第二类种子颗粒大但籽中脂肪酸含量较低，第三类蛋白质含量高但脂肪含量较低；通过主成分分析筛选出综合排名前三的品种为金茶1号、金茶18和金硕茶1号。综上，13份茶树种质可分为高油、大粒、高蛋白三类，其中金茶1号、金茶18和金硕茶1号的综合品质最优，可作为籽用茶树育种的优良亲本。 |

| In order to screen for unique resources among tea trees for seed production, a comparative analysis of the economic traits, quality characteristics, and fatty acid composition of tea seeds was conducted using 13 tea germplasm accessions with high seed-setting rates. Correlation analysis, cluster analysis, and principal component analysis were employed to comprehensively evaluate the traits of the tea seeds. The results indicated that differences existed among different tea tree cultivars in terms of single-plant yield of tea seeds, seed diameter, weight per 100 seeds, kernel-to-shell ratio, fat content, protein content, and starch content. A total of 20 fatty acids were detected in tea seed, with saturated fatty acid content ranging from 1209 g/kg to 33.63 g/kg, monounsaturated fatty acid content ranging from 56.70 g/kg to 138.08 g/kg, and polyunsaturated fatty acid content ranging from 13.09 g/kg to 57.17 g/kg. Correlation analysis indicated that there was a certain degree of correlation among the tea seed traits, and a highly significant correlation among the fatty acid contents. Hierarchical cluster analysis was used to classify 13 tea seed cultivars into three groups, the first group had high fatty acid content in seeds, the second group had large seeds but lower fatty acid content in seeds, and the third group had high protein content but lower fat content. Principal component analysis identified the top three cultivars based on comprehensive rankings as Jincha No. 1, Jincha 18, and Jinshuocha No. 1. In summary, the 13 tea plant germplasm accessions can be classified into three categories: high-oil, large-seed, and high-protein. Among them, Jincha No. 1, Jincha 18, and Jinshuocha No. 1 exhibit the best overall quality and can serve as an elite parent for tea tree breeding for seed production. |
