Abstract

The pearl millet (Pennisetum glaucum) parental line ICM423 (PI572306), released in 1988, is a downy mildew (Sclerospora graminicola) resistant restorer line of a single-cross hybrid cultivar, ICMH423. ICMP423 was derived from the first cycle of the ICRISAT Early Composite which was constituted by random mating of 194 geographically diverse lines, mostly of India origin, that flowered in <45 days from sowing at Patancheru during the 1973 rainy season. Selfed plants were advanced by bulking and a number of cycles of selection for phenotypic similarity and resistance to downy mildew were conducted. Some 1570 progenies with resistance to downy mildew were allowed to random mate. Seeds from the random mating were bulked to form ICMP143. ICMP143 is an elite restorer line with mean grain yield of 1750 kg/ha, medium height (147 cm) and a flowering time of 49 to 57 days from sowing. It produces 3-7 tillers/plant and has a 1000-grain weight of 7.5 g. In 11 disease nurseries in India and western Africa, it had higher levels of resistance to downy mildew than the resistant standard P7-4 (mean and ranges of 4% and 0 to 23% in ICMP423 and 7% and 0 to 49% in P7-4).
