Abstract
An experiment was laid out in 1979 at the Department of Agricultural
Botany, College of Agriculture, Vellayani to study the heterosis in Capsicum
annum L. Nine parents and 36 F1 hybrids were compared. Eighteen economic
attributes including vitamin A, vitamin C, capsaicin and oleoresin content were
studied. All the characters under investigation manifested heterosis over midparental
values though there was wide variation for different traits in different
cross combinations. Maximum heterosis was noticed for number of primary
bradches and vitamin C content. A comparison of average heterosis for various
characters revealed that number of secondary branches topped the list followed
by vitamin C, capsaicin content and number of primary branches. The studies
identified two promising hybrids with desirable attributes namely Purple Round x
Vellanotchi and Pant C1 x Purple Cluster. Negative heterosis was noticed for
two important economic attributes namely number of days taken for blooming
and number of seeds per fruit. For nutritive and quality characters very little
expression of hybrid vigour in vitamin A content was noticed. However, there
was considerable manifestation of hybrid vigour in vitamin C and oleoresin
content.
