Abstract
The investigation entitled “Evaluation and seed production potential of European genotypes
of carrot (Daucus carota L.) under different agroclimatic conditions of Punjab ” was carried
out at Research Farm (Director Seeds), Punjab Agricultural University, Ludhiana (L1) and
KVK Langroya, Shaheed Bhagat Singh Nagar (L2). 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.
