Abstract:

The present investigation was carried out to study the magnitude of genetic variability, correlation and path coefficient among 20 traits in ten amaranthus accessions belonging to Amaranthus tricolor. Comparison of genotypic co-efficient of variation (GCV) and phenotypic co-efficient variation (PCV) for different traits indicated that the values of PCV were higher as compared to GCV due to the influence of environment. High GCV and PCV were observed for leaf length, leaf breadth, stem weight, seed yield per plant and anthocyanin content. High estimates of heritability coupled with high genetic advance were recorded for plant height, number of leaves per plant, leaf length, leaf breadth, leaf weight, stem weight, green yield per plant, seed yield per plant, anthocyanin and nitrate content where heritability ranged from 80.21 to 97.62% and genetic advance from 30.51 to 57.15%, thereby these characters need to be given more importance in selection as these are expected to be controlled by additive genes. Significant and positive correlation of green yield per plant with plant height, stem girth, number of leaves per plant, number of branches per plant, leaf length, leaf breadth, ascorbic acid and crude fibre content was observed. Path analysis revealed that the number of branches per plant exerted the highest direct effect on green yield per plant and was indirectly influenced through days to flower appearance, stem girth, number of leaves per plant, leaf length and leaf breadth. It was concluded that green yield could be increased substantially in vegetable amaranthus through the indirect selection based on characters plant height, number of leaves per plant, leaf length, leaf breadth, green yield per plant, seed yield per plant, anthocyanin and nitrate content.
