Divergência genética em germoplasma de aveias silvestres com base em caracteres multicategóricos e quantitativos

Abstract: Genetic divergence in wild oat germplasm based on multicategoric and quantitative traitsThe wild oats are an important source of genes for breeding programs and their characterization is essential for effective conservation and use. This study aimed to evaluate the genetic divergence among 71 subsamples of wild oats (A. abyssinica, A. barbata, A. brevis, A. fatua, A. longiglumis, A. sterilis, A. vaviloviana and A. wiestii) based on 25 multicategoric and quantitative traits. Analyzes of variance, for quantitat… Show more

“…Four assessed variables (TSW, GP, SW and SL) were responsible for 82.33% of the differentiation among the studied populations, namely, 51.54%, 15.73%, 7.84% and 7.22%, respectively (Table 2). Scheffer-Basso et al (2012) verified that base pilosity of grain and cycle are traits that contribute to a greater percentage for dissimilarity in wild oat. The GY, NB, TGW, PH, and PL contributed less than 2% for differentiation of the studied oat populations.…”

“…The UPGMA clustering method is considered the most simple for the construction of phylogenetic trees, frequently used in the study of variability of germplasms of several species (Campos et al, 2010;Scheffer-Basso et al, 2012;Sobral et al, 2012). It is sufficient for both continuous (Coimbra et al, 2010) and multi-category (Bento et al, 2007;Büttow et al, 2010) variables.…”
