| Abstract | ||||
| This study was conducted during 2009-2010 and 2010-2011 seasons at the Division of Vegetable Science, Indian Agricultural Research Institute, New Delhi, India. Fifteen parents (five cytoplasmic male sterility (CMS) lines and ten fertile lines) and 50 hybrids of carrot were used for this study. Combining ability were assessed in a randomized complete block design with three replications. Substantial genetic variability were existed among parents and their F1s for eleven characters studied. Among the 15 parents, the line IPC53 recorded the highest positive significant gca effect for four characters (reducing sugar, total carotene, ascorbic acid, and Cu) and the second highest significant gca effects for five characters (k, p, Mn, Zn and Fe). Also, the top six hybrids with high per se performance (IPC53 x IPC122, IPC126 x IPC116, IPC98 x IPC16, IPC55 x IPC16, IPC98 x IPC13 Red and IPC126 x IPC76) exhibited high sca effects for total carotene. Conclusively, both GCA and SCA effects were highly significant for all the characters. The variances due to SCA were greater than the GCA variances for most the studied characters except total carotene. Among 50 hybrids, the hybrid (IPC126 x IPC76) showed one from the five best (SCA) for most of the studied quality characters. | ||||
