The evaluation study was conducted for different potato varieties and local genotypes collected from different parts of Chhattisgarh and screened against bacterial wilt and viral diseases complex. The locally collected genotypes have been further categorized on the basis of their distinct growth, yield, quality and disease and insect pest reactions behaviour. The study was carried-out at Department of Vegetable Science, IGKV, Raipur, Chhattisgarh in consecutive years i.e. 2013-14 to 2018-19. The genotypes were screened under bacterial wilt-sick plot condition and recurrent seed tubers material were utilised to evaluate the latent infection of disease. The disease incidence was recorded among the 20 genotypes/ varieties and among them local collection showed extremely low bacterial wilt incidence ranged from 0.10-7.41%. The wilt incidence was recorded 0.1% with genotypes IGP 2012-1 and 1.50% in IGP 2012-5 followed by IGP 2012-7 (0.74%), IGP-2012-2 (1.48%), IGP-2012-6 (2.22%), IGP 2012-4 (6.30%) and IGP 2012-4 (7.41%). Among the released varieties, wilt incidence was ranged from 10.30 % (Kufri Jyoti) to 41.74% (Kufri Pukhraj). The genotype IGP 2012-2 was recorded most promising as recorded 1.48% bacterial wilt infection and 10% viral disease incidence (90% resistance against virus diseases complex).
