Abstract

Identification of slow rusting resistance genes against leaf rust is important for gene pyramiding, gene deployment and developing slow-rusting wheat cultivars to control the disease. Nine hundred and eighty germplasm accessions were screened for their infection response against leaf rust during 2012-2013 season in the field condition and out of which 30 accessions which showed resistance response were selected for seedling resistance test (SRT) and adult plant resistance (APR) during 2013-2014 season. At seedling stage, three accessions viz. EC-635627, EC-635721 and EC-664244 showed resistance which may be the presence of seedling resistant Lr genes. At adult stage, the accessions EC-635627, EC-635705, EC-635721 and EC-664244 showed high resistance to leaf rust. Except the accession EC-635614, remaining twentynine germplasm accessions showed adult plant resistance phenotypically as shown by their lower A-values which may be the presence of effective race-specific resistance genes. The relation between the plot yield and A-value of 30 germplasm accessions was observed to be negatively correlated.
