Genetic Resources of Tropical Tuber Crops

Abstract

Cassava and sweet potato are the two major tropical tuber crops important
for industry, as well as for food. While cassava has a restricted distribution in
humid tropical areas, sweet potato is grown from humid tropics to sub-tropical/
sub-temperate regions in the lower Himalayas. Cassava cultivation has now
been successfully extended 'to sub-humid tropical areas of India. Tuber crops
and their wild species maintained at NBPGR, Trichur station are listed in Table 1.
