38 isogenic lines were studied for the presence of wheat leaf rust virulence during the years 1997-98 to 2001-2002 at Regional Agricultural Research Institute, Bahawalpur. Lr9, Lr19, Lr24, Lr25 and Lr36 were free of reaction whereas Lr3ka, Lr12, Lr13 and Lr17 exhibited resistant reaction. 18 lines (Lr1, Lr2a, Lr2c, Lr3, L3bg, Lr8, Lr10, Lr11, Lr14a, Lr14b, Lr16, Lr20, Lr21, Lr22b, Lr23, Lr26, Lr29 and Lr30) gave high population of virulence and exhibited 20S-100S reaction through out the study period. Lr18 and Lr34 gave improvement in reaction, which may be due to decline in their corresponding virulence. Lr34 is an adult plant resistant gene and can be exploited in combination with other genes. The high frequency of leaf rust virulence for Lr26 was recorded consistently during 4 year because the wheat varieties carrying Lr26 gene remained in the field covering vast area throughout the world. This gene in combination with other genes is effective against prevailing leaf rust pathogens in most of the cultivars in Pakistan. |
