dc.description.abstractAmaranthus (Amaranthus tricolor L.) is a popular leafy vegetable and it is a rich source of vitamin- A, calcium, iron and vitamin-C. The investigation on “Studies on genetic variability, divergence and character association in vegetable amaranthus (Amaranthus tricolor L.)” was conducted in the field of Vegetable Science, Kittur Rani Channamma College of Horticulture, Arabhavi, Gokak (Karnataka). The experiment was laid out in RCBD design with two replications. The treatment included twenty five genotypes collected from various sources were evaluated during kharif season of 2017. The analysis of variance revealed highly significant difference among the genotypes for all the characters studied indicating the higher magnitude of variability in the germplasm. The very high estimates of heritability coupled with high values of genetic advance over per cent mean (GAM) were observed for traits such as leaf area, number of spikes and leaves per plant, iron, vitamin-C, magnesium, calcium, copper, phenols and oxalate content of leaves. This indicates predominance of additive components for these traits and hence direct selection would be more effective in improving these traits. The results of correlation and path analysis revealed that leaf yield per plant had maximum significant positive correlation with number of leaves per plant, stem girth, number of branches per plant, number of spikes per plant and spike length. Number of leaves per plant had maximum direct and indirect effect on leaf yield plant-1. Hence direct selection for these traits would be more useful in the improvement of yield plant-1. Based on Mahalonobi’s D2 analysis, 25 genotypes were grouped into 4 clusters. The intra-cluster distance was found maximum in cluster-IV followed by cluster-III. Top five genotypes viz., HUB-19, HUB-18, HUB-20, HUB-1 and Arka Samraksha were identified on the basis of their per se performance for leaf yield plant-1 these five genotypes were further assessed for their stability.en_US
