Abstract

A study was conducted during 1990-98 to identify new sources of powdery mildew (Erysiphe graminis DC f sp
tritici E. Marchel) resistance among 4 wild and 1 related species of wheat (Triticum aestivum L. emend. Fiori & Paol.).
Testing at adult plant stage under natural conditions as well as at seedling stage using single spore isolates identified 26
sources of resistance among Triticum araraticum (9), T boeoticum (1), Aegilops speltoides (14), A. squarrosa (1) and T
dicoccum (I). This resistance of two accessions of T araraticum (Accessions 4697 & 4698) has been transferred into T
durum Desf and 'NP 200' T dicoccum into 'HD 2329' T aestivum through interspecific hybridization. One backcross
derivative carrying resistance from T araraticum (Accession 4698) showed multiple resistance to powdery mildew, leaf
rust, stripe rust and stem rust under natural conditions at Wellington (Tamil Nadu).
