“…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.…”
