Abstract: A collection of 75 safflower germplasm accessions was evaluated to study genetic divergence, trait association and path coefficients for quantitative traits in augmented design during rabiseasons of 2013-14 atAgricultural Research Station, Annigeri and 2014-15 at College of Agriculture, Vijayapur,University of Agricultural Sciences, Dharwad. At both locations, eight characters exhibited significant values for varieties indicating significantvariability among the accessions. The traits, plant height,days to fifty per cent flowering,capitulum diameter, number of seeds per capitulum and hull percentage were less influenced by environment at both the locations. High broad sense heritability with high genetic advance as per cent mean was noticed for number of seeds per capitulum, biological yield per plant and plant height at both the locations. These traits can be considered in selection of genotypes for crop improvement. The promising germplasm accessions PI248808, PI305534 and PI237548 had high seed yield and accessions PI305534, PI209289, PI209295 and PI291600 had high oil content than the best check. At Vijayapur, seed yield was positively correlated with plant height, number of capitula per plant, biological yield and harvest index and negatively, with rosette period and days to fifty per cent flowering. Path analysis revealed that all significantly correlated traits exhibited positive direct effect on seed yield except rosette period, capitulum diameter and hull percentage. The genetic divergence studies grouped the accessions in to 16 clusters byemploying D2statistic. Genetic divergence was mainly due to biological yield followed by plant height and harvest index. The accessions belonging to Clusters XII, X, XVI and VI could be used for crop improvement as they had high seed yield. Field screening for Alternaria disease revealed no resistance in the accessions screened.Screening of germplasm for aphid resistance revealed tolerance inChelguruki-2,Chelguruki-3,APSC-1,APSC-2,PI307055, 98-25,ASA-04, ASA-07 and ASGPM-07.
