Abstract

In district Chakwal groundnut crop is under pressure due to root rot disease caused byFusarium solani (Mart) Sacc. Evaluation of five groundnut genotypes against root rot namely 02KCG020, No. 334, BARI 2000, Golden and 02KCG05 was conducted in naturally disease infested field of district Chakwal during crop season 2009. Among the tested groundnut genotype, complete resistance to root rot was not observed in any genotype. Minimum disease incidence and mortality, 13 and 8% respectively with disease rating 0-1 was recorded in breeding line 02KCG020. The groundnut variety BARI 2000 was intermediate in resistance to root rot with disease incidence and mortality, 19 and 6% respectively with disease rating 0-1. Groundnut variety No. 334 was the most susceptible variety with disease incidence and mortality, 26 and 17% respectively. In agronomic performance, groundnut genotypes 02KCG020, BARI 2000, golden and 02KCG05 were superior to groundnut variety No. 334.
