为更好的对野生余甘子种质资源进行评价研究,建立数量化、规范化的余甘子种质资源描述系统,于2011—2012年,在云南省农业科学院热区生态农业研究所种质资源圃对80份余甘子种质资源果实的单果质量、果实纵径、果实横径、果形指数、外果皮质量、外果皮厚、可食率、果核质量、果核长、果核宽等10项数量性状指标进行测定。结果表明,以上10个性状存在5.13%以上的变异系数,各性状均存在不同程度的偏正态分布;根据分析结果,提出性状分级标准为1~5个等级,每个等级提出2份异地种质作为参照。该研究为我国余甘子种质资源描述系统数量化、规范化的建立提供了参考依据。
In order to better evaluate the germplasm resources of wild Phyllanthus emblica, establish a quantitative and standardized description system of germplasm resources of Phyllanthus emblica L. from 2011 to 2012 in Yunnan Provincial Academy of Agricultural Sciences, Fruit quality, fruit length, fruit diameter, fruit shape index, exocarp thickness, exocarp thickness, edible rate, fruit quality, fruit length and fruit core width of 80 indica germplasm resources Item quantitative trait determination. The results showed that the above 10 traits had a variation coefficient of 5.13% or more, and all the traits were in different degrees of normal distribution. According to the analysis results, the trait classification criteria were 1 ~ 5 grades and 2 grades Quality as a reference. This study provided a reference for the establishment of quantitative and standardized establishment of the germplasm resources description system in China.
