摘要

Plant morphology is widely adaptive. Phenotypic differentiation among genotypes reflects a balance between natural selection in the local environment, migration of alleles via gene flow, and, at a lower frequency, the acquisition of novel traits through mutation. Teasle gourd [Momordica subangulata Blume subsp. renigera (G. Don) de Wilde] is a rich source of antioxidant vitamins and a raw material for commercial extraction of neutraceuticals. Extensive collection and characterization for evaluation of superior genotypes are important in improvement. The aim of the study was to evaluate genetic diversity of accessions through genetic components analyses, and genetic divergence by multivariate analysis and principal component analysis (PCA). Wide variation occurred for 13 qualitative and 19 quantitative characters. Number of fruit/plant and fruit weight was identified as the most important selection indices for improvement of yield. Based on determination of divergence, the 18 genotypes could be grouped into seven clusters. Geographical diversity was not adequate as an index of genetic diversity. Based on PCA and average values, genotypes "BCTG-1," "BCTG-2," and "BCTG-4" possessed optimum combinations of all variables. Inter-mating between these female clones by inducing staminate, or hermaphrodite, flowers with application of growth substances may be an alternative breeding method for teasle gourd. Desirable characters in hybrids as new varieties can be fixed indefinitely through clonal propagation within a short period of time.

Don）De Wilde]是一种丰富的抗氧化维生素来源和用于商业提取中质化的原料。对卓越基因型评估的广泛收集和表征在改进方面是重要的。该研究的目的是通过多元分析和主要成分分析（PCA）来评估通过遗传成分分析和遗传分歧的遗传分歧。 13种定性和19个定量字符发生了宽的变化。果实/植物和果子重量被确定为最重要的选择索引，以提高产量。基于差异的测定，18个基因型可以分为七种簇。地理多样性并不充足作为遗传多样性指数。基于PCA和平均值，基因型“BCTG-1”，“BCTG-2”和“BCTG-4”具有所有变量的最佳组合。这些雌性克隆之间的相互作用通过诱导雄蕊或雌雄同体，具有生长物质的鲜花可能是Teasle Gourd的替代育种方法。混合动力中所需的特性作为新品种可以在短时间内通过克隆传播无限期地固定。
