Response of groundnut genotypes against root rot disease in district Mianwali

摘要

Root rot caused by Fusarium solani (Mart) Sacc. in groundnut is a serious disease in district Mianwali. Five groundnut genotypes (02KCG 020, No.334, BARI 2000, Golden and 02KCG05) were evaluated against root rot in field under natural inoculum in farmer's field of Mianwali during crop season 2009. No groundnut genotype was completely resistant to root rot. In groundnut genotypes 02KCG020, disease incidence was minimum (10%) with 100% plant survival. The groundnut variety BARI 2000 and golden was intermediate in resistance to root rot with disease incidence 19% each and plant mortality 11% and 8% respectively with disease rating 0-2.Groundnut variety No.334 was the most susceptible variety with disease incidence and mortality 23% and 14% respectively.
