Resistance to powdery mildew (Blumeria graminis f. sp. tritici E. Marchal.) in bread wheat, durum, dicoccum and triticale genotypes

Published on

Powdery mildew resistance genes were postulated in 63
Indian genotypes belonging to Triticum aestivum L., T.
durum, T. dicoccum and triticale. Gene Pm3c in combination
with some unidentified gene(s) was postulated in genotype,
K 9441. Some unknown gene(s) alongwith Pm5 were
identified in eight genotypes, while Pm 5+Pm 8 were
detected in genotype WH 681. Resistance in 22 genotypes
was attributed to gene Pm8 while, 12 genotypes showed
additional resistance ascribed to the unknown gene(s).
Seven genotypes viz., K 9453, HD 2689, HW 3003, HD 2680,
MACS 3011, MACS 3018 and HD 2700 showing differential
behavior to the test cultures. However, infection type
matching technique, could not attribute resistance in these
gnotypes. Triticale genotypes viz., DT 95, DT 46 and DT 91,
Triticum dicoccum genotypes namely, DDK 1013, DDK 1014,
MACS 2574, MACS 2912, MACS 2919, DDK 1009 and DDK
1015 and T. aestivum genotype UP 2450 were resistant to all
the cultures and hence, no resistance gene in these
genotypes could be postulated.
