The genetic diversity among nineteen mandarin genotypes was assessed at Punjab Agricultural University Ludhiana based on fruit chromicity scores. Colour parameters of fruit epicarp, pulp and juice were determined with the help of Hunter Lab colorimetric system as per IPGRI descriptors. The mean value of epicarp CCI was significantly higher (11.91) in W. Murcott followed by Fremont (9.32) and Kinnow (8.54). However, the mean value of pulp CCI of different mandarin genotypes ranged from 4.28 to 11.30 with average value of 6.66. The pulp CCI was maximum (11.30) in Daisy which was statistically at par with Darjeeling (10.51). The data revealed that mean value of juice CCI was maximum (9.78) in Daisy which was statistically at par with W. Murcott (9.68), CRS-4 (9.14), Clone-11(9.03) and Kinnow (8.86). The clustering analysis showed that genotypes were grouped across the sub-groups based on their quantitative colorimetric values without clear evidence of their geographical distribution. The study concluded that W. Murcott, Fremont, Kinnow and Daisy are distinct genotypes having higher chromicity scores. Thus, this study will help citrus breeder to select distinct mandarin genotypes for targeting better fruit colour parameters in citrus improvement programme.
