Abstract
The objective of the present study was to evaluate the relative tolerance of five wheat genotypes viz., K-8434, K-307, NW-1014, K-88 and HUW-468 in a pot experiment during Rabi 2008-09 and 2009-10 at five levels of irrigation water salinity viz. 3, 6, 9 and 12 dSm-1 with normal water in the department of crop physiology, C.S. Azad University of agriculture and technology, Kanpur. Grain yield of all varieties were significantly reduced along with increase in the irrigation water salinity, but the magnitude of reduction was found minimum of 40.57% in K-8434 and maximum of 67.52% in HUW-468 from normal to 12 dSm-1 salinity of irrigation water. Similarly, the reduction in germination percentage of sown seeds from control to 12 dSm-1 EC salinity was also recorded with minimum of 20% in K-8434 and maximum of 38% in variety HUW-468.
