Kales and Collards: Superfoods for health and wealth

Abstract

Kale is a collective term used for various kales and collards that have originated basically from wild cabbage (Brassica oleracea) and are the result of evolutionary changes brought about by either natural selections or hybridisations. Kale, in general, demonstrates superior nutritional composition compared to conventional leafy vegetables positioning it as a comprehensive essential source of nutrients. Phytochemical analysis shows that it contains higher total antioxidant activity than other leafy green vegetables, primarily due to the presence of carotenoids, flavonols and glucosinolate-derived isothiocyanates conferring significant protection against various diseases. ICAR-Central Institute of Temperate Horticulture, Srinagar conserves more than 65 genotypes of kale including
Kashmiri landraces (Khanyari, Hanz Haak, GM Dari, Kawdari) and exotic varieties (Lacinato, Siberian and Russian kales) that acts as an invaluable reservoir for targeted breeding. Furthermore, kale based value-added products developed by the institute offer functional food availability contributing to regional nutritional security and public heath goals extendable to national level.
