The aim of study to estimate the broad sense heritability of S1 progenies and to quantify the genetic variance through multivariate analyzes of S1 progenies from landrace maize populations grown in the southern region of Rio Grande do Sul. The experimental design utilized was the augmented blocks, with ten S1 progenies groups (Amarelão, Argentino Branco, Argentino Amarelo, Branco Vermelho Indio, Branco Oito Carreiras, Caiano Rajado, Cateto Branco, Criolão Dente de Ouro and BRS Planalto), and two commercial controls, the simple cross hybrids Pioneer 30F53 and Agroeste 1590, allocated in four repetitions. The traits grain depth and spike insertion height express the largest estimates of broad sense heritability. The S1 progeny Argentino Amarelo provides the largest estimates of broad sense heritability for the set of evaluated traits. The S1 progenies Caiano Rajado, Criolão, Branco Roxo Índio, BRS Planalto, Dente de Ouro, Amarelão and Branco Oito Carreiras have similar heritability patterns for the studied traits, allowing to employ a similar selection strategy in the next generations. The S1 progenies from landrace maize populations present genetic variability for the agronomic traits studied. [ABSTRACT FROM AUTHOR] |
