ABSTRACT :

Hybrids produced by crossing Capsicum annuum cultivars Hungarian Red Long (red, long fruit and semi-determinate growth) and Spanish Lilac Round (lilac, round fruit and unrestricted growth) were investigated for differences in carotenoid composition, endogenous antioxidant content and storage stability of powdered product over 6 months' storage under refrigeration and at ambient temperatures. The cultivars and hybrids varied substantially in capsanthin/capsurobin ratio, capsanthin/violaxanthin ratio, and red carotenoid, ascorbic acid and alpha -tocopherol contents. Lilac fruits had higher capsurobin, violaxanthin and beta -carotene contents. The F1 hybrids all produced lilac, mid-length fruits. The subsequent generation had 12 combinations of fruit colour and shape. Chemical analysis revealed that both red and lilac coloured fruit of semideterminate plants had better quality attributes, red pigments and antioxidant content than those from unrestricted ones. Lilac mid-length fruits from semideterm

inate plants had the highest levels of carotenoids, ascorbic acid and tocopherol. Powder produced from such fruit had the highest colour stability during storage. Fruits from unrestricted plants had the lowest carotenoid and antioxidant contents, and their powders had the lowest retention of red pigments after 6 months in storage.
