Investigations were carried out on dry matter, total nitrogen, total chlorophyll, carotenoid contents and nitrate reductase activity (NRA) in the leaves of three genotypes of wheat viz, HUW-206, HP-1102 and HUW-234 in order to find their relationship with the yield potential in these varieties. Results indicated that dry matter in leaves, total chlorophyll in the first leaves and carotenoid in the first and second leaves were highest in the variety HUW-206. The NRA was significantly correlated with the nitrogen content of leaves and yield potential.
