Abstract :
Three hundred and ninety eight chickpea germplasm accessions were evaluated for blight resistance under greenhouse as well as in field conditions during the winter season of 2003-04. The results revealed that 18 genotypes with disease score 1 to 3 were resistant at seedling stage while 69 were at flowering stage. Fifty three genotypes with disease rating of 4-5 were moderately resistant at seedling stage and 125 at flowering stage, whereas the rests were susceptible. It is proposed that initial screening of chickpea germplasm should be undertaken at seedling stage under greenhouse condition to save time and labour. The genotypes showing resistance at this stage may subsequently be tested against aggressive isolates under field as well as greenhouse conditions at flowering stage. Ultimately, the genotypes with different sources of resistance may be utilized to build pyramid resistance into a single genotype.
