A downy mildew resistant, high yielding maize hybrid CoH2 has been released for general cultivation in Tamil Nadu. The hybrid has a duration of 95-100 days and 10-15 days earlier than Ganga.5 and Co.1. Under irrigated conditions, the hybrid yields 5472 kg of grain per hectare which is 41.9 and 66.6 per cent more yield than Ganga.5 and CoHI respectively. The plant height of the hybrid is 225-260 cm. The cobs are fully covered with husk. The grains are bold, yellow in colour and flinty in texture and are acceptable to consumers. The downy mildew incidence in CoH2 was lower (1.1 per cent) while it was 2.9 and 28.3 per cent in CoH1 and Ganga. 5 respectively
