Abstract

Paspalum scrobiculatum is widely distributed in damp habitats across the Old World tropics. It is harvested as a wild cereal in west Africa and in India.The species was domesticated in India some 3,000 yr ago. It is grown in India from Kerala and Tamil Nadu in the south, to Rajasthan, Uttar Pradesh and West Bengal in the north. Kodo millet is variable but lacks racial differentiation. The species was apparently domesticated across its range of present-day cultivation. HybridizationwithwildP. scrobiculatum , which commonly invades fields of kodo millet, obscures racial differentiation. Weedy kodo is harvested with the crop, making it difficult to distinguish wild and cultivated complexes ofP. scrobiculatum. Wild, weed and cultivated kinds merge in all characters studied.
