Summary
The present paper deals with the chromosome numbers of nine species of wild and cultivated Yams. Five species, namely,D. pubera, D. deltoidea, D. hispida, D. belophylla andD. esculenta, have been worked out for the first time. InD. alata andD. bulbifera different chromosome races for the Indian forms have been recorded besides the ones reported by previous workers. It is interesting to observe that the Japanese races ofD. oppositifolia andD. pentaphylla are higher polyploids than the Indian forms reported here.
