Twenty six accessions of Capsicum annum with varied
ripening color were screened for total carotenoids (0.004-
0.47%), red carotenoids (0-0.27%) and yellow carotenoids
(0.004-0.2%) and also to obtain some new or useful alleles
associated with ripening color in chilli, using gene-specific
marker. Considerable genetic variability for carotenoids
was observed along with the allelic variations of candidate
gene Capsanthin capsorubin synthase (Ccs). The results
revealed that Ccs gene coding region was present in yellow
pepper line LCA 1068 (Aparna) suggesting Ccs gene
deletion is not a prerequisite for change in color from red
to yellow. Ccs coding region contained no introns but did
exhibit polymorphism among chilli lines studied resulting
in amino acid changes. Novel allelic variants were found
in Byadagi Dabbi (dark red) and LCA1068 (yellow) in the
study, which could provide candidate/allele specific
molecular markers for selection of lines that may be used
in chilli quality breeding for varied colors
