Abstract
Forty six AVT wheat genotypes received from the Indian Institute of Wheat and Barly Research, Karnal (Haryana) during Rabi 2017-18 were screened for testing their resistance against selective and virulent pathotypes of stem and leaf rusts under glass house condition. These genotypes were tested at seedling stage against thirteen pathotypes of stem rust viz. 11, 21-1,34-1, 40A, 42, 42-B, 117, 117A, 117-2, 117-3, 117-6, 122 and 184 and fourteen pathotypes of leaf rust viz. 77, 77A1, 77-4, 77-5, 77-9, 104A, 104-1, 104-2, 12A, 12-2, 12-3, 12-5, 162A and 108. Among them, seventeen wheat genotypes viz,. HI 1544 (C), GW 495, DBW 110 (C), DDW 47(d), MP 3288 (C), GW 491, GW 493, DBW 235, HI 1624, MACS 6222 (C), DBW 168 (I) (C), GW 495, HI 1625, PBW 770, GW 492, MPO 1336 (d) and MACS 6695 were found resistant to stem rust disease of wheat. While, thirteen wheat genotypes viz,. HI 1544 (C), GW 495, MP 3288 (C), AKAW 4924, GW 491, GW 493, HI 1624, MACS 6222 (C), HI 1625, UAS 428 (d) (C), GW 492, GW 1346 (d) and DBW 93 (c) were found to be resistant to leaf rust disease of wheat. Whereas nine genotypes viz,. HI 1544 (C), GW 495, MP 3288 (C), GW 491, GW 493, HI 1624, MACS 6222 (C), HI 1625 and GW 492 were resistant to both rusts under glasshouse condition. These AVT genotypes resistant to both rust pathotypes are recommended for further breeding programme.
