Assessment of some Indian wheat genotypes and breeding lines for adult plant resistance (APR) against stripe rust

Abstract

Stripe or yellow rust of wheat caused by Puccinia striiformis west end f. sp. tritici is devastating foliar disease and is considered of immense importance in cool and humid wheat growing parts of the world. A total of 41 wheat genotypes collected from different institutes of India were evaluated for Adult Plant Resistance to stripe rust. The field studies revealed fifteen genotypes viz: PBW 750, PBW 752, PBW 779, PBW 780, JAUW 672, WH 1184, HI 1619, 13th HTWYT 719, 25th HRWSN 2105, 47th IBWSN 1185, 32nd SAWSN 3011, HD 3086, 22nd SAWYT 316, PBW 763 and PBW 801 exhibiting resistant reaction with Average Coefficient of Infection (ACI) ranging from 0.45 to 2.
