摘要

本研究的目的是研究雀稗(Paspalum urvillei Steud)表型变异。与12个动物技术性状相关，以更好地了解来自7个国家的41个美国农业部GRIN平台的多样性。首先，我们根据表型数据进行了结构推断，确定了两个结构组，大多数巴西材料属于第一组。然后进行主成分分析和主坐标分析，为每个结构组内的每个特征绘制小提琴图。其次，我们对数据进行空间聚类，并利用非加权对组方法与算术平均聚类。简而言之，通过从第二表型结构群中引进美国农业部的种质资源，巴西野田鼠的育种计划可能会取得成功。

Understanding the extent of phenotypic variability in accessions of Paspalum urvillei Steud. from the USDA NPGS

The objective of this study was to investigate the phenotypic variability in Paspalum urvillei Steud. related to twelve zootechnical traits to better understand the diversity of 41 accessions from the USDA GRIN platform from seven countries. First, we performed a structure inference based on the phenotypic data, identifying two structure groups, and the majority of Brazilian accessions belonged to the first group. Then, we performed principal component analysis and principal coordinate analysis, making Violin plots for each trait within each structure group. Next, we performed spatial clustering of the accessions and utilized an unweighted pair group method with arithmetic mean clustering. In brief, the Brazilian P. urvillei breeding programs may be successful by importing USDA germplasm resources from the second phenotypic structure group.

期刊介绍： The Iheringia, Série Botânica is a publication edited by the Museu de Ciências Naturais, Fundação Zoobotânica do Rio Grande do Sul, since 1958. The name Iheringia is actually a tribute to Hermann von Ihering (a German researcher who became a Brazilian citizen) and his important studies in the Natural Sciences.The journal has the mission of publishing articles, reviews and original scientific notes that cover diverse areas in Botany, and may be written in Portuguese, Spanish and English. The journal is widely available in both international and national scientific community. The issues are published and distributed twice a year to 118 national institutions and 152 international institutions. The distribution is either free of charge or by exchange.
