GENETICAL STUDIES OF QUALITY TRAITS IN CARROT (DAUCUS CAROTA L.)

Published on

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.
 

Keywords: Carrot, Asiatic, European, JH:arotene, total sugars, gene action.
