Colour of glumes, anthers and silk differed among varieties but there was no variation for the colour of stem, leaf or central vein. Manakamana-2 and Hill Pool White had pure white coloured cobs while Arun-4 and Narayani had white and pink/red coloured cobs. Hill Pool White had a white dent seed type and others were yellow flints. Arun-4 required less GDU to reach 50% Tasseling (589), 50% silking (625) and physiological maturity (1312) while Hill Pool White required the most GDU i.e. 798, 829 and 1704 for 50% Tasseling, 50% silking and physiological maturity, respectively. Manakamana-2 attained the largest leaf area index (LAI) 2.54 followed by Hill Pool White (2.41) and Arun-4 (2.24) at the silking stage. Narayani produced the highest harvest index (HI) 0.38 followed by Arun-4 (0.36) and Manakamana-2 (0.34). Narayani had the highest shelling per cent (82%) followed by Hill Pool White (79%) and Arun-4 (78%).Collection: CIMMYT Publications Collection
