Abstract

Malabar tamarind (Garcinia gummi-gutta (L.) N. Robson) is an important horticultural genetic resource having multifaceted uses and is being used as a flavouring agent besides being source of gamboge, seed fat and medicine in the humid tropics. Considering the increasing demand, reducing dependance on wild/ semi-wild population and promotion of cultivation is the need of the hour. Seedling progenies are known to have considerable variability of commercial significance. To identify the superior germplasm with desirable traits, systematic efforts are required. Though such screening from natural population could help in identifying superior genotypes, the data on various yield related traits could be misleading due to differences in the growing conditions of the natural stands. In the present study, the conserved germplasm was evaluated to understand the variations for leaf, fruit and seed morphological parameters apart from their harvesting patterns, yield traits, drying recovery etc. Results revealed that collections showed significant variations for these parameters and unique types viz. GG-05 with early harvesting season (late April onwards), thin peel (5.55 mm), longer pedicel (6.05 mm), and GG-04 with higher yield traits were identified. Further, collections UUF-01 and UUF-03 exhibited irregularity in bearing.

印度湿热带经济作物 Garcinia gummi-gutta (L.) N. Robson 园艺特征的变化

马拉巴尔罗望子（Garcinia gummi-gutta（L.）N. Robson）是一种重要的园艺遗传资源，具有多方面的用途，在潮湿的热带地区，除了是甘宝、种子脂肪和药物的来源外，还被用作调味剂。考虑到日益增长的需求，当务之急是减少对野生/半野生种群的依赖，推广种植。众所周知，种苗后代具有相当大的商业价值变异性。要识别具有理想性状的优良种质，需要系统的努力。虽然从自然种群中进行筛选有助于确定优良基因型，但由于自然种群的生长条件不同，各种产量相关性状的数据可能会产生误导。在本研究中，对保存的种质进行了评估，以了解叶片、果实和种子形态参数的变化，以及它们的收获模式、产量性状、干燥恢复等。结果表明，这些种质资源在这些参数上表现出明显的差异，并确定了独特的类型，即采收季节早（4 月下旬开始）、果皮薄（5.55 毫米）、花梗长（6.05 毫米）的 GG-05 和产量性状较高的 GG-04。此外，UUF-01 和 UUF-03 系列在结实方面表现出不规则性。

期刊介绍： Genetic Resources and Crop Evolution is devoted to all aspects of plant genetic resources research. It publishes original articles in the fields of taxonomical, morphological, physiological, biochemical, genetical, cytological or ethnobotanical research of genetic resources and includes contributions to gene-bank management in a broad sense, that means to collecting, maintenance, evaluation, storage and documentation. Areas of particular interest include: -crop evolution -domestication -crop-weed relationships -related wild species -history of cultivated plants including palaeoethnobotany. Genetic Resources and Crop Evolution also publishes short communications, e.g. newly described crop taxa, nomenclatural notes, reports of collecting missions, evaluation results of gene-bank material etc. as well as book reviews of important publications in the field of genetic resources. Every volume will contain some review articles on actual problems. The journal is the internationalized continuation of the German periodical Die Kulturpflanze, published formerly by the Institute of Plant Genetics and Crop Plant Research at Gatersleben, Germany. All contributions are in the English language and are subject to peer reviewing.
