Thirteen germplasm lines of Chenopodium album (from CA-I to CA-XIII) were evaluated in a randomized block design with three replications to estimate the foliage yield and its seven contributing quality traits for three successive cuttings. The variability and interactions operating at various levels were also studied. The mean foliage yield was maximum for CA-II (3.03+/-0.39 kg/plot), followed by CA-VII (2.94+/-0.27 kg/plot) and CA-VI (2.41+/-0.20 kg/plot). Moisture content showed a constant decrease in all germplasm lines with successive cuttings except for CA-IX in the 3rd cutting. Protein concentrations exhibited a strong trend of increase with each successive cutting with the maximum in the 3rd cutting. Protein conc. showed the highest heritability in the 1st cutting (96.35%), whereas for ascorbic acid it was in the 2nd and 3rd cuttings. Carotenoid and ascorbic acid conc. exhibited consistently high genetic gain in all the three cuttings.
