چکیده
|
Seventy six bread wheat (triticum aestivum l.) candidate lines and commercial cultivars from pakistan were postulated for their leaf rust genes resistance. since limited information available on the genes,the main objective of the study was to postulate the known lr genes conferring low seedling reactions to 14 pathotypes of puccinia triticina in 76 pakistani wheats. eleven leaf rust resistance genes were present either singly or in combination: lr1 (in 12 lines),lr3 (4),lr9 (2),lr10 (28),lr13 (27),lr14a (2),lr16 (9),lr17 (8),lr23 (18),lr26 (36),lr27+31 (5) in the tested material among which lr26 was the most frequent while lr9 was the least frequent.
