Abstract

The genetic variability in plant populations can be estimated through multivariate analysis, which allows to analyze the genotypes based on a set of traits to identify the traits with the greatest influence for the divergence and the correlation between them. In this sense, the objective of the present work was to estimate the genetic divergence between golden flax lines using multivariate analysis for initial plant selections. For this purpose, 73 lines, in addition to the control, were tested in a randomized complete block design, with three replications, and traits of cycle, stature, and yield were measured. Twelve groups were obtained based on the Mahalanobis distance estimate and Tocher cluster, and the technical length was the most important trait for the dissimilarity. The line of group XI was promising, with early maturation and satisfactory seed productivity. The graphic of dispersion of the canonical variables showed the most divergent lines, and the greatest divergence was observed between groups III and IV. Multivariate analysis was an important tool for the initial choice of superior golden flax.

多变量分析在金亚麻初选中的应用

植物群体的遗传变异性可以通过多变量分析来估计，可以根据一组性状来分析基因型，从而确定对差异和它们之间的相关性影响最大的性状。在这个意义上，本工作的目的是利用多变量分析来估计金亚麻株系之间的遗传分化。为此，在对照的基础上，采用3个重复的完全随机区组设计，对73个品系进行了周期、株高和产量等性状的测定。基于马氏距离估计和Tocher聚类得到12个类群，技术长度是差异的最重要特征。11组品系成熟早，种子产量满意，前景看好。典型变量的离散曲线呈现出最发散的曲线，其中ⅲ组和ⅳ组差异最大。多变量分析是初步选择优质金亚麻的重要工具。
