Diverse European carrot genotypes were characterized by morphological, biochemical and seed production potential during 2018-19. Analysis of variance showed significant differences for quantitative traits with respect to locations, dates of sowing and genotypes. GGE Biplot model was used to produce biplot graphs which display the variability of genotypes and G×E interactions and visualized the stable performance of genotypes for all the quantitative and qualitative characters. Morphological, biochemical and seed production potential of European carrot genotypes were best in second location (KVK, Langroya). Mean values of morphological characters like root length, root weight, root girth and total root yield (kg/plot) was significantly maximum of genotypes viz., Carrot Nantes, P-35, P-41 and Carrot Early Nantes when sown in first week of November. The genotypes such as P-35, P-5, Arka Suraj and P-16 showed significantly higher values in terms of total soluble solids, carotene content and sugar content. The genotypes Carrot Nantes, PCO-4, PCO-6 have significantly higher seed quality and seed production potential when sown in first week of January.ennullThesis
