Abstract: Coriander is a crop of significant nutritional as well as medicinal value, due to its wide adoptability it could be cultivated under a wide range of environmental conditions. The existence of wide range of genetic variability in a coriander population for economically important characters enables the improvement of crop in the desirable direction. Correlation coefficient studies reveals the relationship between various characters and also provides the way to know the association prevailing between highly heritable characters with most economic characters. In this line the present study was undertaken in coriander to understand the relationship between the herbage yield and it component characters. A field experimentation was laid out at Horticulture Research Station, Devihosur, Haveri District, Karnataka, in Randomized Complete Block Design (RCBD) for sixty one Devihosuru Coriander Collections (DCC) -1 to DCC-61 including DWR-1 and Ajjampura in two replication. Observation on herbage yield and its associated parameters were studied viz Plant height (cm), Number of primary branches, Number of secondary branches, Number of leaves, Fresh weight of the plant (g) Dry weight of the plant (g), Herbage yield (g), Days to 50% flowering, Number of umbels per plant, Number of umbellets per umbel, Number of seeds per umbellet, 1000 seed weight (g), Seed yield per plant (g), Days to maturity, Harvest index (%). were recorded. The analysis of variance revealed highly significant difference among genotypes for twenty eight characters. Genotypic correlations were higher than phenotypic correlations indicating highly heritable nature of the character like seed yield per plant showed highly significant and positive correlation with number of leaves at 60 DAS, fresh weight of the plant at 60 DAS, number of umbels per plant at 60 DAS, number of seeds per umbellet at 60 DAS, thousand seed weight and crop duration both at genotypic and phenotypic level whereas, number of primary branches at 60 DAS, showed significant and positive correlation at genotypic level only, Since, these association characters are in the desirable direction, selection for these traits may improve the yield per plant.
