Abstract:
The present investigation was carried out to study different selection parameters for herbage yield and its important yield attributing traits in 52 genotypes of vegetable amaranth (Amaranthus spp. L). Genotypic coefficient of variation values ranged from 8.52% (days to 50% flowering) to 66.08% (total herbage yield ha^-1) during Kharif 2019-20. The PCV values showed similar trends as GCV and ranged from 8.74% (days to 50% flowering) to 67.46% (total herbage yield ha^-1). The values of heritability estimates were high for all the traits and ranged from 78.10% (leaf: stem ratio) to 95.95% (total herbage yield ha^-1). The expected genetic advance as percent of mean varied from 16.16% (Days to first harvest) to 133.35% (Total herbage yield ha^-1). High genetic advance as percentage of mean (GAM) which coincide with high heritability were observed for total herbage yield ha^-1, leaf area, fresh leaf weight plant^-1, fresh stem weight plant^-1, fresh green yield plant^-1, plant height, stem diameter, leaf width, leaf length, petiole length and number of leaves plant^-1.These characters may be used as early indicators in selection programmers of vegetable amaranth. Based on the performance, promising genotypes Arka Suguna, CO-1, KVA-18, Nisco Red, KVA-34, Pusa Kiran, KVA-28, KVA-32, Pusa Lal Chauli and KVA-1 have been found superior among the genotypes which can be used in breeding programmers for crop improvement.
