Abstract Crop breeders are frequently confronted with a challenge of shortlisting a few most likely to be productive early segregating generations in terms of high frequency of superior recombinant inbred lines from among a large number of segregating generations which are normally being developed to save substantial resources. The breeding potential of five F2 populations derived from parents differing for fruiting habit traits was assessed based on first- and seconddegree statistics and frequency of transgressive segregants for number of fruits plant-1, average fruit weight and fruit yield plant-1 using 2016 and 2017 rainy season data. Based on higher mean, wider absolute range and standardized range, and higher phenotypic coefficient of variation and frequency of transgressive segregants, F2 population derived from JL 9 8B was identified as the one with better breeding potential than that derived from other crosses.

Introduction The human diet is incomplete without chilli (Capsicum annuum L.), as it is being used as spice, condiment, and vegetable for its appealing color, flavor, and pungency. It is one of the most important economic spice-cum-vegetable crops worldwide (Poulos 1992) and is ranked second among solanaceous vegetables after tomato in terms of production (Bosland 1995). Fruits are also a rich source of calcium, magnesium, iron and potassium (Pawar et al. 2011). Red fruits contain carotenoid pigments such as lycopene and zeaxanthin which are known to possess anticancer properties (Kim et al. 2014; Ghasemnezhad et al. 2011; Bosland and Votava 2000). Fruit extract has antimicrobial properties that are important for human health (Perucka and Materska 2007). The multipurpose use of chilli fruits has created huge demand in the world spice trade. The annual trade of chilli is approximately 17 per cent of world spice trade owing to its high cash values and consumption (Ahmed et al., 2000). India is the foremost producer and exporter of chilli followed by China, accounting for 26 per cent of global pepper production. Chillies
