Development of crop cultivars for increased and stable production in dry lands of the semi-arid tropics uri icon

abstract

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