Characterization of ICRISAT-bred restorer parents of pearl millet uri icon


  • Pearl millet (Pennisetum glaucum), primarily grown forgrain production on more than 26 million ha in the aridand semi-arid tropical (SAT) regions of Asia and Africa,is a highly nutritious cereal crop with wideagroecological adaptation. India, the largest producer ofthis crop at global level, cultivates pearl millet on about>9 million ha contributing to more than 90% area of thecrop in the Asian region. It is a highly cross pollinatedcrop, and single-cross hybrids generally give 20?30%more yield than open pollinated varieties (Rai et al.2006). With the availability of commercially exploitablecytoplasmic-nuclear male sterility (CMS) systems inpearl millet, the national agricultural research system(NARS) and the private seed sector in India focused theirbreeding programs on hybrid development. This led tothe development and adoption of a diverse range andlarge number of hybrids (>80 in 2011) and now occuping>4.5 million ha area, which is about half of the total pearlmillet area being cultivated in India (Rai et al. 2006). TheInternational Crops Research Institute for the Semi-AridTropics (ICRISAT) also aligned its breeding program todevelop promising hybrid parental lines for supportingAsian pearl millet hybrid program
