The yield potential as well as quality of chilli is affected by a number of biotic and abiotic stresses. The genetic improvement of this crop, especially for characters like resistance to biotic and abiotic stresses using conventional breeding methods are laborious, time taking and also needs a large experimental area. So, an attempt was made to study callus induction in chilli genotypes by using hypocotyls as explant to complement conventional breeding and expedite capsicum improvement. The study was carried out on callogenic response of chilli species with different hormones revealed that MS medium supplemented with NAA 2.5 mg/1+ BAP 2.5 mg/1 was found most suitable for callus induction to both the genotypes viz., Capsicum annuum and Capsicum frutescens. When NAA and BAP were used in combination early initiation of the callus was observed with fragile and pale yellow colour in both the genotypes of chilli. Among the chilli genotypes evaluated, the average callus formation was (77.24%) in case of C. annuum, whereas (79.20%) in C. frutescens. Hence, callus induction was significantly better in C. frutescens as compared to C. annuum.
