Abstract

The study was conducted with the objective to estimate the nutritional composition from 35 diverse genotypes of (Capsicum annuum L.) which were previously uninvestigated, for selection of highly nutritive genotypes as a parent for further hybridization program. The genotypes were divided into three groups. Group I (thin type), group II (intermediate) and group III (cherry chillies). Mineral contents calcium, iron, magnesium, manganese, zinc and copper were analysed using atomic absorption whereas potassium and sodium were estimated through flame photometer. Phosphorus was determined using a spectrophotometer. Moisture, protein, fat, ash and crude fiber contents were estimated by the AOAC method, while carbohydrate content was estimated by the difference method. In relation to macro minerals highest magnesium (287.52 mg/100), calcium (114.0 mg/100g) and potassium (286.30 mg/100g) was observed in group II, whereas phosphorus was highest in group III (29.20 mg/100g). In the case of micro minerals highest iron (109.0 mg/100g) and copper (0.21 mg/100g) content were depicted in a group III, sodium (15.90 mg/100g) in group II, while manganese (0.50 mg/100g) and zinc (0.20 mg/100g) were highest in group I. As far as concern proximate composition, fats (2.15 %), ash (8.93 %) and protein (9.09 %) was maximum in group III. Moisture (11.86) and carbohydrates (52.28 %) was highest in group II. Based on these results chilli peppers contain a high amount of magnesium, potassium, calcium and iron content, these chilli peppers could be preferably selected for the breeding purpose for the further crop improvement program.
