ABSTRACT
Genetic variability, heritability and genetic advance for yield and yield attributing traits were studied by evaluating twenty seven genotypes along with two checks (Arka Suguna and Arka Arunima) of vegetable amaranth (Amaranthus tricolor L.). The estimates of PCV and GCV were high for plant height, stem diameter, number of branches per plant, leaf area index, number of leaves per plant, leaf weight per plant, leaf stem ratio at 30, 60 and 90 DAS, leaf length at 30 and 90DAS, stem weight per plant at 30 and 60DAS, total foliage yield, total chlorophyll content, carotenoids, protein content, ascorbic acid and oxalate content indicating the existence of wider genetic variability for these traits in the germplasm. High heritability coupled with high genetic advance expressed in percentage of mean was observed for plant height, stem diameter, stem weight per plant , number of branches per plant, leaf length, leaf width, leaf area index, number of leaves per plant, leaf weight per plant, leaf/stem ratio at 30, 60 and 90 DAS, foliage yield per plant, total chlorophyll content, carotenoids, protein content, ascorbic acid, oxalate content, iron content, folic acid indicating that these traits were mainly governed by additive gene action and responsive for further improvement of these traits.
