RL 111-3P2, RL 113-1P2, RL 116P3, RL 124-2P2, RL 136P RL 136-1P1, RL 137P1, RL 138P2, RL 140P1 and RL 141P2, were resistant to leaf rust (Puccima recondata J sp tritict race 77.1) and 13, namely RL 105-1P2, RL 107P1, RL 110P1, RL 112P1, RL 117-2P2, RL 124-2P2, RL 28-2P2 RL 133-1P1, RL 136P2, RL 139-1P1, RL 141-1P2, RL 142P2, and RL 143P2 were resistant and 4 moderately tesistant to powdery mildew (Erystphe graminis f sp tritict). However, three derivatives viz., RL 124-2P2, RL 136P1 and RL 140P1 showed resistance to both the diseases at seedling stage. Rest of genotypes were moderate to highly susceptible.
