Heritability estimate formula
WitrynaEstimation of heritability in broad sense Broad sense heritability (h2) of the all traits were calculated according to the formula as described by Allard (1960) as follow: h 2 bs = [(σ G) / (σ2 P)] × 100, where: h 2 bs = heritability in broad sense; σ G = Genotypic vari-ance; σ2 P = Phenotypic variance. Estimation of genetic advance WitrynaI calculated BLUPS for days to flowering in rice.
