Abstract: The estimation of genetic parameters, especially in early generations, is very useful for directing the selection process in breeding programs. The present research was undertaken to estimate heritabilities in the broad sense, narrow sense and using parent-offspring regression in F3 soybean populations from six two-way crosses, originated from the Soybean Breeding Program of Faculdade de Ciências Agrárias e Veterinárias (UNESP), Jaboticabal campus. It was used the family design with common checks located ten p… Show more

“…This means that there is an opportunity to improve the maturity of Dering 1 by utilizing those early maturing genotypes. Days to maturity in soybean is reported to have a high heritability indicates that these trait can be inherited to the offspring (Costa et al 2008;Osekita and Olorunfemi 2014). In term of water scarcity, adaptation of plants to drought stress can be through drought escape, dehydration postponement, and dehydration tolerance (Turner et al 2001).…”

“…Martin and Wilcox (1973) evaluated three F2 populations for FPH and estimates of heritability were 63% (Beeson × L66-1085-1-270), 74% (Amsoy71 × L66-1085-1-239) and 50% (Wayne × L66-1085-1-251). Costa et al (2008) also evaluated 57 F2 and F3 families derived from six populations, in which the estimates of broad sense heritability were 82% (BRSMG Renascença × BR-16), 48% (MGBR95-20937 × IAC Foscarin31), 45% (MGBR95-20937 × BR-16), 66% (BRSMG Liderança × Embrapa-48), 43% (BRSMG Liderança × IAC Foscarin31), and 95% (BRSMG Renascença × Embrapa-48) for the respective crosses. When heritability is higher than 50%, it means that phenotypic variation is more affected by genetic factors than environmental factors (Stansfield 2005).…”

“…This result show that 66% of the overall variation could be explained by genotypic differences among individuals in F2 population. Therefore, selection for FPH in early generation like as F2 population is possible and efficient for maintaining phenotype to the following generation (Costa et al 2008).…”

“…A seleção em gerações precoce de soja, F 2 ou F 3 , pode ser utilizada em programas de melhoramento para descartar progênies não promissoras (Carvalho et al, 2009). Ademais, as estimativas de parâmetros genéticos em gerações iniciais possibilitam dirigir o processo de seleção dos genótipos mais promissores (Costa et al, 2008), além de definir genitores com maior probabilidade de gerar recombinantes livres de interações indesejáveis (St Martin et al, 2009).…”
