dc.description.abstractRadish (Raphanus sativus L.) is a popular root vegetable and it is a rich source of Vitamin- C. The investigation on “Characterization of different genotypes of radish (Raphanus sativus L.) in northern dry zone of Karnataka” was conducted in the field of Vegetable Science, Kittur Rani Channamma College of Horticulture, Arabhavi, Gokak (Karnataka). The experiment was laid out in RCBD design with two replications. The treatment included thirty genotypes collected from various sources were evaluated during kharif and rabi seasons of 2017. The analysis of variance revealed highly significant difference among the genotypes for all the characters studied indicating the higher magnitude of variability in the germplasm in kharif, rabi and also in pooled average of both the seasons. The very high estimates of heritability coupled with high values of genetic advance over per cent mean (GAM) were observed for traits such as leaf area, root diameter, root length, root to leaf ratio, root weight, root yield plot-1, root yield ha-1, ascorbic acid, calcium content, fibre content, isothiocynates, potassium, protein, sodium, total phenols and total sugars in both the seasons. This indicates predominance of additive components for these traits and hence direct selection would be more effective in improving these traits. The results of correlation and path analysis revealed that root yield per hectare had maximum significant positive correlation with leaf area, root to leaf ratio and rot weight. Root weight had maximum direct and indirect effect on root yield hectare-1. Hence direct selection for these traits would be more useful in the improvement of yield hectare-1. Based on Mahalonobi’s D2 analysis, 30 genotypes were grouped into 5 clusters in kharif, 8 clusters in rabi and 9 clusters in pooled average of seasons. The intra-cluster distance was found maximum in cluster-I in kharif, cluster-IV in rabi and cluster-II in pooled average of seasons. Top five genotypes viz., HRESB-8, HRESB-7, HRESB-10, HRESB-16 and HRESB-9 were identified on the basis of their per se performance for root yield and top five viz., VRRAD-202, HUB-2, HUB-1, HRESB-24 and HRESB-6 for quality and these ten genotypes were further assessed for their stability.en_US
