Genetic variability, heritability and genetic advance studies in Amaranthus (Amaranthus tricolor L.)

Abstract

The experiment was conducted during 2016-17 at Horticulture Research Farm, Department of Applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedkar University, Lucknow to study the “genetic variability, heritability and genetic advance in Amaranthus(Amaranthus tricolor L.)”.The experiment was laid out in randomized block design with three replications. The analysis of variance revealed significant difference among all the genotypes for the attributes. Higher genotype coefficient of variation (GCV) was observed for seed weight per plot, spikes per plant, leaves per plant and branches per plant. Thephenotype coefficient of variation(PCV) was also found higher in leaves per plant followed by branch, spike per plant and seed weight per plant. Maximum heritability (broad sense) was obtained for seed weight per plot followed by test weight, green leaves yield per plant and days to full maturity. The genetic advance was found maximum for length of leaves followed by test weight, days to full maturity and percent dry matter.
