Abstract: Chilli or hot pepper (Capsicum annuum L.; 2n=24) is one of the most valuable commercial spice-cum-vegetable crops grown in India and belongs to the family Solanaceae. In India, area under chilli is 0.956 m. ha with an annual production of 0.945 m. t. and its productivity is 0.9 t dry chilli/ ha. Main reasons for low chilli productivity in India are; i) majority of the area is under rainfed cultivation, ii) area under chilli hybrid varieties is very low (2.5–3.0 %), & iii) susceptibility to major pests & diseases. Hybrid seed is the seed of an F1 generation sold for commercial production of the crop. Despite of high seed cost, there is increasing demand for hybrids because of high yield, adaptability, uniformity and resistance to biotic and abiotic stresses. Moreover, hybrid/ heterosis breeding is comparatively easy to vegetable breeders as it is easy to incorporate resistant genes for biotic and abiotic stresses and also horticultural traits in F1 hybrid and also the right of the bred variety is protected in terms of parental lines. Chilli peppers express considerable amount of heterosis (20-50%) for yield, hence are amenable for exploitation of hybrid vigour as F1 hybrids.
