Title : Generation mean analysis of yield and quality traits in carrot (Daucus carota L.)

Abstract :

Carrot is important root vegetable being used as raw and cooked form (gajar halwa). The root is main edible part, breeding should be focus on traits that can increase root production. The productivity of carrot depends upon the cultivar and its yield contributing characters. Information of the genetics analysis of yield traits is essential for developing new breeding lines which can contribute to improvement of specific traits. The production should be based on yield contributing traits like plant height, number of leaves, leaf length, root length, root diameter, core diameter, root weight, TSS, yield per plant, root fresh weight and root dry weight. As a result, the findings aid in the production of carrot hybrids or cultivars. Genetic analysis of yield traits of carrot was estimated through three cross combinations, and the results revealed the existence of additive [d], dominance [h], additive x additive [i], additive x dominance [j] and dominance x dominance [l] gene actions. In most cases, duplicate epistasis was seen for traits such as plant height, number of leaves, leaf length, core diameter, TSS, root fresh weight, and root dry weight. The presence of additive, dominance, additive, and dominance interaction effects was indicated by similar signs of (h) and (l) for the expression of root length, root diameter, root weight, and yield per plant, indicating the presence of additive, dominance, additive, and dominance interaction effects. The complementary type showed that these traits might have a significant degree of heterosis, and that recurrent selection could be employed to improve these traits in future generations.
