dc.description.abstractTo study the varietal behaviour of wheat with regard to different strains of Azotobacter chroococcum, as experiment was conducted in which six varieties of wheat such as C-306, PBW-343, WH-283, WH-542, WH-147 and WH-711 were treated with two mutants of A. chroococcum Mac27 and HT54 at three levels of fertilizer such as O kg N ha-1, 90 kg N ha-1, 120 kg N ha-1 in terms of agronomical parameters under pot house conditions. Response of wheat varieties was studied towards A. chroococum in plant height, seed yield, total nitrogen content and total biomass. Variety C-306 showed best response towards both the strains of A. chroococcum. Mac27 showed better response as compared to HT54. Root exudates of these wheat varieties were analyzed for chemotactic behaviour and other components such as sugars, amino acids, phytohormones and organic acids. Glutamic acid and some other unidentified amino acids were detected in both inoculated and uninoculated wheat varieties. Succinic acid was present in wheat varieties WH-711 and WH-147. Maleic acid and some unidentified organic acids were detected in inoculated and uninoculated wheat varieties C-306, PBW-343, WH-283 and WH-542.en_US
