Abstract:

The field and laboratory screening of 31 accessions were carried out against fruit rot of chilli caused by Colletotrichum capsici under natural pressure condition. Out of 31 accessions eight were found resistant, remaining twenty three accessions found moderately resistant at 90 days after transplanting. The reaction during harvest stages varied from that of 90 days after harvest which recorded, 2 resistant accessions, eight moderately resistant accessions, twenty moderately susceptible accessions and Byadagi Dabbi as susceptible. During in vitro screening18 accessions were found resistant, 8 were moderately resistant, 3 were moderately susceptible and 2 were susceptible to the pathogen during green stage of the fruit. The reaction of chilli fruits during turning red stage recorded, 18 accessions as moderately resistant, 8 as moderately susceptible and one (DCA-298) was susceptible. The reaction varied in red stage of fruit development wherein, 5 accessions were resistant, 18 accessions were moderately resistant, 6 were moderately susceptible and 2 were susceptible to the pathogen. The accessions DCA-67, 69, 189, 302 and 305 were reacted resistant to the C. capsici in field and artificial screening. Hence, these accessions having the resistant genes which can be used for resistant breeding programme.
