Foram avaliados 17 acessos (previamente selecionados pela Embrapa Gado de Corte) em delineamento em blocos ao acaso com tr?s repeti??es. Os acessos foram avaliados por meio de cortes a 25 cm do n?vel do solo em parcelas de 4,0 m2, com espa?amento de 1 m entre linhas. A partir das an?lises dos resultados, foi poss?vel notar que apenas as caracter?sticas taxa de alongamento de colmo, taxa de alongamento de folha e comprimento final da lamina foram estatisticamente diferentes entre os acessos avaliados. Para taxa de alongamento de colmo o coeficiente de varia??o do ambiente apresentou valor elevado. O coeficiente de varia??o genot?pico da taxa de alongamento de colmo foi o maior entre as vari?veis avaliadas, indicando o potencial de ganho na sele??o para o mesmo. Para o comprimento final da l?mina, foram observados coeficiente da varia??o do ambiente e coeficiente da varia??o genot?pica inferiores ? taxa de alongamento do colmo, contudo, foram obtidos herdabilidade e raz?o CVg/CVe semelhantes. Os coeficientes de varia??o residual e genot?pico da taxa de alongamento foliar foram intermedi?rios em rela??o ?s demais caracter?sticas e assumiram valores pr?ximos, que permitiram a estimativa de uma raz?o CVg/CVe pr?xima da unidade. O alongamento de folhas apresenta maior potencial para ser inserido no processo de avalia??o e sele??o de forrageiras devido a sua alta herdabilidade e raz?o entre os coeficientes de varia??o genot?pico e residual.Submitted by Jos?

Were evaluated 17 accessions in a complete block design with three replicate. The accessions were evaluated by cutting at 25 cm from de level soil in plots of 4 m?, with 1 m intercrop. It was possible to note only the stems elongation rate, leaf elongation rate and leaf length were statistically different between the accessions. To stems elongation rate we had high environmental coefficient of variation. In spite of this the genotypic coefficient of variation was also the higher between the characteristics evaluated, indicating potential to reduce this by selection. To leaf length, were observed genotypic and environmental coefficient of variation lower than the stems elongation rate, however were observed similar heritability and genotypic/environmental coefficient of variation rate. The genotypic and environmental coefficient of variation of leaf elongation rate were intermediated between the other characteristics and had next values, so the genotypic/environmental coefficient of variation rate was the higher in the experiment and next from one (0,93). The leaf elongation rate has potential to be included in the process of evaluation and selection of forage plants duly its high heritability and favorable environmental/genotypic coefficient of variation rate.porUFVJMUniversidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM)A concess?o da licen?a deste item refere-se ao ?
