<b>Estimation of genetic parameters and repeatability coefficients of forage characters in elephant-grass (<em>Pennisetun purpureum</em> Schum.) clones</b> - DOI: 10.4025/actasciagron.v26i4.1823
Abstract
Seventeen clones of elephant-grass were evaluated in a randomized block experimental design using split-plots, with 4 replications, from February/95 to December/97, resulting in 12 cuts (as environments), in the municipality of Campos dos Goytacazes, Rio de Janeiro, Brazil. The aim of this study was to obtain estimates of genetic parameters and repeatability coefficients of the following variables: dry matter production (DMP), height (H), stem diameter (SD) and number of tillers per meter (TN). The genotypic determination coefficient (H2) values varied from 33,49% (DMP) to 84,34% (H). Nine, five, three and two measures for the traits DMP, H, SD and TN, respectively, were enough to predict the real value of genotypes, for a coefficient of determination of 80%Downloads
