The present investigation was aimed to identify the resistant germplasms against Colletotrichum capsici in vitro by artificial inoculation. Ten isolates of Colletotrichum capsici collected from different regions of Vidarbha and Marathwada (Maharashtra), Bidar district (Karnataka) and Guntur district (Andra Pradesh) showing varied type of pathogenic ability against chilli variety Jayanti and designated as strongly, moderately and weakly pathogenic on the basis of per cent leaf area covered by the disease. The varietal screening studies revealed that, remarkable diversity could not observed among the isolates. Strongly pathogenic Cc6 (Guntur) and Cc9 (Akola) recorded the highly susceptible reaction against Jayanti and susceptible reaction against Phule Jyoti, Pusa Jwala, G-4 and NCH-162-14-17 and moderately susceptible reaction against AKC-406-1. Isolate Cc6 exhibited moderately susceptible reaction to AKC-97-20-06-2 and TEJ-F5-01-2-24-14-RIII-3-1-6 and susceptible reaction against Hybrid-1, whereas isolate Cc9 exerted susceptible reaction against AKC-97-20-06-2 and TEJ-F5-01-2-24-14-RIII-3-1-6 and highly susceptible reaction against Hybrid-1. Isolate Cc8 (Washim) was exhibited moderately resistant reaction against Phule Jyoti, while isolate Cc10 (Jalna) exerted highly susceptible reaction against AKC-406-1. All other isolates of C. capsici produced varied type of reaction against host varieties, indicating existence of variability among C. capsici isolates. Initiation of symptoms, maximum incidence and acervuli production was also comparable among the isolates relates to varied type of aggressiveness.
