Abstract

The International Crops Research Institute for the Semi- Arid Tropics (ICRISAT) conducts inter-disciplinary and partnership-based research for the genetic improvement of its mandate crops. During the 1970s and 1980s, the pearl millet improvement at ICRISAT, Patancheru, emphasized on: (i) developing a diverse range of traitspecific composites, based on the germplasm largely from the Western and Central Africa; (ii) improving them by the process of recurrent selection, principally for grain yield and downy mildew (Sclerospora graminicola (Sacc.) Schroet ) resistance; and (iii) developing open-pollinated varieties (OPVs) (Rai and Anand Kumar 1994). The improved composites, OPVs, and breeding lines derived from them, were disseminated for worldwide utilization. These germplasm, improved populations, and breeding lines were also utilized at ICRISAT, Patancheru, mostly for pedigree breeding which was aimed at developing a wide and diverse range of improved trait-specific breeding lines and hybrid parents employing higher grain yield potential and downy mildew (DM) resistance, as the main selection criteria. Limited efforts were also made to develop composites, OPVs, and breeding lines with additional resistance to smut (Tolyposporium penicillariae Bref.) and ergot (Claviceps fusiformis Loveless).
