Genetics of micronutrients and their relationships with grain yield and other traits have a direct bearing on devising effective strategies for breeding biofortified crop cultivars. A line × tester study of 196 hybrids and their 28 parental lines of pearl millet (Pennisetum glaucum (L.) R.Br.) showed large genetic variability for Fe and Zn densities with predominantly additive gene action and no better-parent heterosis. Hybrids with high levels of Fe and Zn densities, involved both parental lines having significant positive general combining ability (GCA), and there were highly significant and high positive correlations between performance per se of parental lines and …

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)
