ABSTRACT

Garcinia gummi-gutta is valued for its dried fruit rind used as a souring agent in traditional cuisine and for the extraction of natural hydroxy citric acid (HCA) in the formulation of anti-obesity nutraceuticals. The species is widely distributed in Kerala State but is not yet an economically profitable crop in the region. Promising germplasm screening based on the fruit mass traits of 180 trees was performed leading to the selection of 35 candidates plus trees (CPTs) characterized by the fewest fruits to weigh 1 kg (i.e., the largest fruits) with two fruit bearing seasons. Fruit mass data of 35 CPTs showed significant (P < .001) variations and highest fresh fruit mass (1091.27 kg), and dry rind mass (48.18 kg) recorded in CPT 6 and is 40-fold higher mass than mean fruit mass (25.4 kg) of 180 trees. Multivariate analysis and web diagram-based ranking supported selection of CPT 6 as a promising candidate tree. In the tree improvement programs through nutraceutical enrichment, the superior germplasm selected (CPT 6) in the present study can use effectively.

摘要

藤黄果胶因其干果皮在传统美食中用作酸味剂以及在抗肥胖保健品配方中提取天然羟基柠檬酸 (HCA) 而受到重视。该物种在喀拉拉邦广泛分布，但在该地区还不是一种经济上有利可图的作物。基于 180 棵树的果实质量性状进行了有前景的种质筛选，最终选择了 35 棵候选树（CPTs），这些候选树的特点是在两个结果季的果实重量最少为 1 公斤（即最大的果实）。35 个 CPT 的果实质量数据显示出显着的 (P < .001) 变化和最高的新鲜果实质量 (1091.27 kg)，CPT 6 记录的干果皮质量 (48.18 kg) 是平均果实质量 (25.4) 的 40 倍kg) 的 180 棵树。多变量分析和基于网络图表的排名支持选择 CPT 6 作为有前途的候选树。在通过营养丰富的树木改良计划中，本研究中选择的优良种质（CPT 6）可以有效利用。
