Abstract
Pearl millet (Pennisetum glaucum (L) R. Br.) is a major warm-season “nutricereal” grown on ~34 million ha across the world with majority of area (>95%) in the arid and semi-arid tropical (SAT) regions of Asia (~11 million ha) and Africa (~22 million ha) (FAO, 2020). India being the largest producer with an average production of 8.61 million tonnes and productivity of 1243 kg ha-1 occupies an area of 6.93 million ha (Directorate of Millets Development, 2020). It is a highly cross-pollinated crop with an outcrossing rate of more than 85%. The protogynous flowering and wind-borne pollination favors cross-pollination, making open-pollinated varieties (OPVs) as the natural cultivar state of this crop. OPVs, however, are not amenable to achieving as much heterozygosity and the consequent heterosis as it is possible in singlecross hybrids. Furthermore, OPVs are highly heterogeneous and hence morphologically more variable than single-cross hybrids. It has been observed that single-cross hybrids generally give 20-30% more grain yield than OPVs (Rai et al. 2006). Based on these considerations, and with the availability of a commercially exploitable cytoplasmic-nuclear male sterility (CMS), the National Agricultural Research System (NARS) in India took the first significant step in the world to embark on grain hybrid development. With the rapid growth of a vibrant seed industry, pearl millet research in India, both in the private and the public sector, is now almost all directed towards hybrid breeding. In alignment with the regional priority in Asia region, ICRISAT’s pearl millet improvement research at Patancheru playing a pivotal role in developing diverse range of improved breeding lines and potential hybrid parents, leaving the development, testing and release of hybrids to the NARS and the private sector.....
