摘要

本研究的目的是利用形态描述子对秘鲁乌卡亚利农业试验站保存的山药薯蓣基因型的遗传变异进行评估。对30个三叶草基因型的38个形态性状进行了10年的评价;从数据中估计了Shannon-Weaver多样性指数(H’)和变异系数,并进行了主成分分析和聚类分析。表型多样性指数较高的质量性状为:叶柄花青素(0.86)、块茎内颜色(0.86)、叶柄颜色(0.81)和茎颜色(0.80)。变异系数最高的数量性状为:单株块茎重(33.01)和块茎产量(32.99)。其中,块茎宽度、单株块茎重和块茎产量是主要的性状组成部分(29%)。五组基因型也被确定为具有统计学显著差异,其中B组因其在更短的收获天数内获得更高的产量而突出。本研究揭示了三叶草基因型的广泛形态多样性;这些结果可用于加强秘鲁亚马逊地区这一重要物种的保护、管理和遗传改良计划。

Genetic variability of yam (Dioscorea trifida) genotypes in the Ucayali region, Peru
The aim of this research was to assess genetic variability of yam Dioscorea trifida genotypes using morphological descriptors for the germplasm collection conserved in the Agricultural Experiment Station in Ucayali, Peru. Thirty-eight morphological traits were evaluated for 30 D. trifida genotypes over ten years; from the data we estimated the Shannon-Weaver diversity index (H’) and the coefficient of variation and performed principal component analysis and cluster analysis. Qualitative traits with high phenotypic diversity index were: petiole anthocyanin (0.86), internal tuber color (0.86), petiole color (0.81) and stem color (0.80). The quantitative traits with the highest coefficient of variation were: tuber weight per plant (33.01) and tuber yield (32.99). Seventy-six percent of the morphological variability is explained by four principal components, the first component is constituted by the characters tuber width, tuber weight per plant, and tuber yield (29%). Five groups of genotypes were also identified with statistically significant differences, where group B stands out for its higher yield in fewer days to harvest. This research reveals wide morphological diversity in genotypes of D. trifida; these results can be used to strengthen the conservation, management, and genetic improvement initiatives of this important species in the Peruvian Amazon.
