ABSTRACT
Wheat cultivars Pirsabak-91 (P-91), Khyber-87 (K-87) and Tarnab-78 (T-78) were irradiated with 10kR, 20kR, 30kR and 40kR doses of gamma irradiation. The cultivars showed significant reduction in plant height, survival percentage & 1000-grain weight under the influence of high gamma rays doses (30kR & 40kR) excepting days to germination. Germination of all the cultivars was significantly delayed in response to all the gamma rays doses and low dose (10kR) increased the plant height in case of Pirsabak-91. Higher gamma rays doses (30 & 40kR) also created abnormalities in plant height. All the cultivars responded differently to different gamma rays doses with respect to some of the characters.
