Résumé
Sorghum ( Sorghum bicolor (L.) Moench) is a staple food crop in the semi-arid tropical areas of Africa and India. It is also an important feed and forage crop in other parts of the world. In India, the development of short-duration and shortstatured sorghum hybrids resulted in a quantum jcrmp in productivity from 560 kg ha" in 1970 to 1020 kg ha" in 1996. However, yield potentials of sorghum hybrids are not fully realized as they are highly susceptible to grain moulds, which not only cause yield loss but also reduce grain quality and market value. For any effective kharif hybrid breeding programme, grain mould resistant male-sterile and restorer lines are essential prerequisites. Efficient exploitation of resistant genotypes in breeding grain mould resistant parental lines requires knowledge of the number and diversity of genes involved and of their mode of action in determining resistance...
