Resumo: | The research aims to estimate the coefficient of genotypic determination (hm2) and index "b" for quantitative traits in camucamuzeiros able to germplasm bank of Embrapa Eastern Amazon. Evaluated the Solimões accesses; 1002; 1004; 1005; 1007; 1010; 1011; 1012; 1013; 1014 and 1015 The experimental design was a randomized block with dugs repetitions. The variables evaluated were: plant height (PH), the main diameter of 60 cm of soil (DC), number of stems (NC), leaf length (LL), leaf width (LF) stem and leaf area (AF ). Were effected-analysis of variance, estimated the genetic, phenotypic and environmental variance, the coefficients of genotypic determination of genetic and environmental variation, and index "b" for the characters The results showed that, except for plant height (0,26c hm2 = b = 0.24), the other characters were effective as descriptors for evaluation of genetic variability among the accessions. Estimates of genetic variability, the coefficient of genotypic determination (0.67 to 0.90) and the index "b" (1.01 to 2.18) reached high values, indicating the existence of genetic variability among accessions, and the possibility of making simple phenotypic selection for the traits number of stems, length and leaf width and leaf area. |

Avaliaram-se os acessos Solimões; 1002; 1004; 1005; 1007; 1010; 1011; 1012; 1013; 1014 e 1015. O delineamento experimental foi em blocos ao acaso com dugs repetições. As variáveis avaliadas foram: altura da planta (AP), diâmetro do caule principal a 60 cm do solo (DC), número de caules (NC), comprimento da folha (CF), largura da folha (LF) e área foliar (AF). Efetuaram-se analise de variância, estimaram-se a variância genética, fenotípica e ambiental, os coeficientes de determinação genotípico, de variação genética e ambiental, e índice "b" para os caracteres Os resultados mostraram que, a exceção de altura da planta (hm2= 0,26c b = 0,24), os demais caracteres mostraram-se eficientes como descritores para avaliação da variabilidade genética entre os acessos. As estimativas da variabilidade genética, do coeficiente de determinação genotípico (0,67 a 0,90) e do índice "b" (1,01 a 2,18) atingiram valores elevados, evidenciando a existência de variabilidade genética entre os acessos, e a possibilidade de efetuar seleção fenotípica simples para os caracteres número de caules, comprimento e largura da folha e área foliar.Universidade Federal Rural da Amazônia/UFRA2011-05-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/259Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 46 No 1 (2006): RCA; 81 - 88Revista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 46 n. 1 (2006): RCA; 81 - 882177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
