Book Description
Twenty pearl millet genotypes representing hybrids, inbreds, popultion bulks,experimental varieties derived from populations and synthetics, along with a local check contributed by the cooperators, were tested in the IPMAT-2, 1976. Results were reported from 26 locations in 7 countries in the semi-arid tropics. The excellent support of cooperators is gratefully acknowledged. Data were received on grain yield, plant height, flowering, and disease incidence. Location summaries with statistical analyses are presented for each reporting site. Summary means over all locations are also presented for yield, plant height, days to 50% bloom and downy mildew. Results o stability analysis over 19 locations are also included. The hybrids with highest grain-yield averages over all locations were ICH 105, BK 560, ICH 13, and ICH 108. Among the populations, experimental varieties, and synthetics, Ex Bornu, WC-CX75, and Syn. 7601 gave good performances. Data from locations in West Africa and India indicate that Ex Bornu, PHB 14, WC-CX75, and NC-SX75 possess more "stable" resistance to downy mildew. The data support the view that this system of international evaluation provids an opportunity to locate areas of adaptation and identification of stable resistances to downy mildew.
