Abstract

Global food security is at high risk due to climate change. Wheat being the leading cereal of Pakistan finds a pivotal position in food security. Adaptation strategies to combat the adverse effects of climate change must focus on identification and use of genotypes that are efficient in the use of available nitrogen. In a sand culture study, fifteen wheat genotypes were compared under non-stressed (irrigated) conditions to identify nitrogen efficient genotypes having deep root system. Significant (P ? 0.05) differences were observed amongst genotypes for all the traits being studied. The results revealed that Farkhr-e-Sarhad took up maximum nitrogen (47 mg plant-1) and minimum nitrogen was taken up by accession 11172 (31 mg plant-1). Maximum rooting depth of 76 cm was attained by accession 11277 and minimum of 43 cm was attained by NRL-0517. The study generated information on nitrogen uptake potential and rooting depth of Pakistani wheat genotypes. It provided baseline data for the exploitation of deep rooting and high nitrogen uptake capability towards the development of wheat varieties.
