Abstract:
Wheat (Triticum aestivum) is an important food crop of India ranks next to rice contributing about 27 percent of total food production. Karnal bunt of wheat caused by Neovossia indica, has become a potential threat to wheat production in our country. Hence, for minimizing the losses caused by Karnal Bunt need inexpensive and environmentally safe management practices. It was, therefore considered desirable to identify resistant to Karnal bunt for the new bread wheat strains. Colony characters of different isolates from diseased wheat plants were collected from different localities of Kanpur as well as adjoint areas and were observed that the isolates obtained from CRF Nawabganj, CRF Araul, CRF Deegh Chaubepur and Mandhana were fast growing in nature as their colony size ranged from 8.6 to 8.2 cm. with partially fluffy mycelium while isolates from NDF Kalyanpur, CRF Saini, Vegetable farm, Kalyanpur and CRF Manimau were slightly slow in nature, colony size 7.2 to 7.4 with fluffy dark brown mycelium. Mycelium septate, profusely branched, septa are more abundant in older mycelium than younger ones. The teliospore is darkening brown, spore measure 22 to 49 micron. The spores germination from a start, stout mycelium primary sporidia had mean length and with ranging from 64.4 to 78.8 µm and the secondary sporidia had mean length and width ranging from 11.9 to 1.30 µm and 2.00 to 2.03 µm Forty wheat genotype planted at Nawabganj Research From C.S.A. University of Agriculture & Technology Kanpur in which none of the genotype showed immune reaction or 0% disease under artificial condition, 22genotype below 10% disease intensity, 11genotype below 15% disease intensity, 4 genotype below 20% disease intensity namely HD 3043, C306, HD 3133 and K 1213 and only HD 3090 below 40% disease intensity.
