Hence an approach has been made to increase the economic potential of traditional cultivars of millet as a strategic crop, which enhances agrobiodiversity of the region through mixed cropping and mixed farming systems. This paper attempts to explain a value added marketing chain approach adopted by M.S.Swaminathan Research Foundation in conserving the agrobiodiversity in Kolli Hills region in Tamil Nadu.
