An experiment was laid out in Randomized Complete Block Design with twenty five genotypes collected from different sources were evaluated in two replications. Crops growth, yield and quality attributes under field experiment was revealed a significant difference, thus indicating the existence of variation among the genotypes. For the yield characters UHSB C-76, UHSB C-32-1, UHSB C-23-1 and Pusa Rudhira were performed better with maximum root weight (117.60, 116.70, 103.80 and 111.00 g), root yield per plot (13.35, 13.29, 13.15 and13.05 kg/plot) and root yield per hectare (22.55, 22.26, 22.05 and 21.20 t/ha), respectively. The root length, root width and core diameter were recorded highest in the genotypes UHSB C-3-1(17.75, 4.16 and 1.66 cm respectively). The highest TSS was registered in genotype UHSB C-44-3-1(9.00 0B). Whereas, maximum dry matter content was noticed in UHSB C-44-3-1 (15.60 %). The genotypes UHSB C-32-1 and UHSB C-44-3-1 were registered with maximum reducing sugar of 2.48 and 2.45 per cent, respectively. The maximum non-reducing and total sugars were indicated in the genotype UHSB C-44-3-1 that was 1.86 and 4.30 per cent respectively. Among different genotypes, the highest ß-carotene and total carotenoids were recorded in UHSB C-44-3-1 (4.95 and 8.98 mg/100g, respectively). The highest total anti-oxidant per cent recorded in Pusa Asita (12.38 %). In minimally processing, it was found that the carrot genotypes UHSB C-44-3-1, UHSB C76, UHSB C-23-1 and Arka Suraj were retained the freshness, microbially safe and acceptable after 14 days of storage. Carrot genotypes took 8 to10 hours for drying in cabinate dryer and 10 to 15 days in solar drying. However, mean sensory scores of dehydrated carrots for parameters like colour and appearance, taste and overall acceptability were maximum in the cabinate dried roots. The genotypes UHSB C-76 and UHSB C-44-3-1 were scored highest mean sensory scores in dehydrated products. In considering the performance of different genotypes with respect to growth, yield, quality and processing traits the genotypes UHSB C-76, UHSB C-44-3-1, Arka Suraj, UHSB C32-1 and UHSB C-23-1 were found to be best suited for cultivation in Bengaluru rural district comes under Eastern Dry Zone of Karnataka.EnglishThesis
