Abstract
With a view to develop nutritious ridge gourd
variety, a field as well as a laboratory study was conducted to quantify and
enumerate the genetic control for antioxidant properties and mineral content in
fruits. The hybrids were found to be superior over their parents for various
nutritional traits such as ascorbic acid, total carotenoids and total phenolics
content; in vitro antioxidant activity in the form of DPPH-RSA, ABTS-RSA and
CUPRAC; and P, K, Ca, Na, S, Fe, Zn and Mn content in the fruits. All the nutritional
parameters exhibited higher values of dominance variance over the additive genetic
variance, more than unity value of average degree of dominance and low
narrow-sense heritability (\50 %). The antioxidants and mineral content in the
fresh fruits are predominantly attributed by the non-additive genetic
component.
Hence, the various tools of hybrid breeding
would be useful to breed antioxidants- and minerals-rich genotypes of ridge gourd
(Luffa acutangula Roxb.).
