Abstract
The 1988 International Pearl Millet Downy Mildew Nursery (IPMDMN) containing 30 test entries (5 resistant germplasm accessions and 25 breeding lines and varieties) and 3 checks (1 resistant and 2 susceptible) was sent to 12 locations, 6 in India and 6 in West Africa. Data were received from all locations. Highest levels of downy mildew (DM) were registered at Bengou, Niger (47% mean DM severity for test entries), followed by other West African locations and then Indian locations. All test entries had higher mean DM severities (generally more than two fold) across West African locations than across Indian locations, except ICMR 87018 which had 51% in India and 37% in West Africa. Highest across location DM resistance was found in P 1449-3 (3% DM), P 310-17 (4%), and ICMP 423 (7%). The 1988 results suggest several possible virulence differences among pathogen populations at the various test locations.
