A study was undertaken to evaluate the growth performance and grain quality of eight modern wheat varieties grown under rainfed and irrigated conditions. Wheat varieties used in the experiment were aghrani, akbar, ananda, balaka, barkat, kanchan, pavon and sonalika. In irrigated condition, one flood irrigation was applied at 28 days of sowing to saturate the soil up to 15 cm depth. The wheat varieties differed significantly (P less than 0.05) with respect to plant height and 1000-grains weight, grain and straw yields, protein, amylose, ash and K contents in grains. The highest grain yield obtained in aghrani (2.16 t ha-1) was statistically identical to those found in kanchan (2.08 t ha-1), akbar (2.06 t ha-1) and barkat (2.02 t ha- 1. The highest protein content was found in barkat (13.75%), which was followed by ananda (12.65%), akbar (12.55%), sonalika (12.5%), aghrani (12.35%) and kanchan (12.25%). Balaka had the lowest grain protein content (11.55%). The highest amylose content were found in barkat (24.4%) and was followed by balaka (24.25%), aghrani (23.6%), akbar (23.2%), ananda (23.05%) and kanchan (21.75%). Application of irrigation improved the plant characteristics like grain and straw yields, protein, amylose, P, K and S contents in grains compared to wheat grown under rainfed conditions. Among the eight varieties of wheat barkat, aghrani, akbar and kanchan are the promising varieties than the others with respect to grain and protein yields.
