Increasing the grain yield and its stability in dry lands of the tropics of Asia and Africa, as the horne to a vast impoverished humanity,'contipues to be a major challenge for agricultural research and development Development of genetically enhanced cultivars with high yield potential, appropriate maturity, an'd resistance to biotic and abiotic stress factors is an effective approach to increasing and stabilizing the production in these regions. Advances possible through this approach are illustrated with the impacts made in pearl millet (Pelllliselul11 glaucum), a warm~season cereal; and chickpea (Cicer arielillum), a cool-season legume, which are amongst the five mandate crops of the International Crops Research Institute for the Semi-arid Tropics (ICRISAn. The research in this paper is largely the work done by ICRISAT in partnership with the national agricultural research systems and advanced research institutes. The convention,!l approach of enhancement both in pearl millet ang chickpea has been highly successful. Progress has also been made in the areas of molecular marker-assisted selection in both crops, and in wide hybridization and transgenic technology in chickpea to improve those traits that are less amenable to genetic manipulation through conventional methods of genetic enhancement.
