Abstract

Stripe rust of wheat serious biotic stress to wheat aiming in the reduction of yield losses with biotrophic nature of the pathogen attacks mainly the foliage parts and makes it render for photosynthetic ability of the host. Host manipulation with genetic advancement one of the major steps in the breeding programme. The durability of the cultivar can be achieved with stacking of minor gene and their combinations with major R-gene The postulated gene identified diversified resistance patterns with various combination of APR and ASR gene under field conditions and the frequencies of the postulated genes as Yr16 (22.9%), Yr18 (59.0%), Yr29 (44.2%), Yr9 (47.5) and Yr2 (73.7%) respectively, Yr16 postulated germplasm shows strong field resistance at adult plant stage with disease response of R to RMR for Pst Pathotypes such as 78S84, 46S119, 110S119 and 238S119.
