Abstract

Genetical studies were conducted in carrot (DallclIs carota L.) in. triple test-cross design involving European and Asiatic cultivars to determine the role of additive, dominance and epistatic genetic components in five selected quality traits. Epistasis was observed for all the traits. The additive x dominance ( f) and dominance x dominance d,) gene interactions were important for dry matter and total sugar content. Both additive and nonadditive genetic variances were significant for total soluble solids and p-earotene contents. The additive (D) genetic components of variation were more pronounced for ascorbic acid content. Dominance in the range of overdominance was recorded for total soluble solids, while itwas partial in the expression of other traits.
