WebJan 1, 2024 · The genetic gain in NLB resistance realized by the example maize breeding program after each cycle of selection can be observed by comparing the average level of NLB resistance within the selected populations with the average level of NLB resistance of base population as shown in Fig. 2. (Assume that resistance is scored such that larger … WebThe residual effect (h) was calculated using the formula (Dewey and Lu, 1959) as: Where: R2 = Σrijpij: ...

Web100 , GA=k x σ2p x H 2; GA as percent of mean=(GAM)= = 100 Where; x̅/GM= phenotypic trait population (grand mean). GA is genetic advance; is a constant = 20.06 at 5% selection intensity; Estimation of broad sense heritability (H 2) and genetic advance as percent of mean (GAM) assuming selection intensity of 5% for individual and combined ... Webwhere, EGA represents the expected genetic advance under selection; σ ph is the phenotypic standard deviation; h b 2 is heritability in broad sense and k is selection intensity The genetic advance as percent of population mean was also estimated following the procedure of Johnson et al., (1955). Genetic advance per population mean = (EGA ... WebGenetic Advance Expected genetic advance under selection (GA) was computed according to the formula given by Johnson et al. (1955). GA = (h2) Where, is selection intensity; is phenotypic standard deviation and h2 is heritability of the trait expressed in fraction. Genetic Advance as Percentage of Mean insulated dryer ducting
