Description Pearl millet (Pennisetum glaucum (L.) R. Br.) is an important cereal crop, grown on 26 million ha
in the arid and semi-arid tropical regions of Africa and Asia, with India having the largest area of
10 m ha. It is a highly cross-pollinated crop with high degree of heterosis for grain yield, which
can be exploited through hybrids and open-pollinated varieties (OPVs) as the two broad cultivar
options. A commercially viable cytoplasmic-nuclear male sterility (CMS) system discovered in
the USA and made available to pearl millet improvement programs in India laid the foundation
for hybrid development in India in 1960s, which is the only significant pearl millet hybrid
growing country in the world. Since then, extensive use of this CMS source in hybrid
development, and search for new CMS sources was made at ICRISAT and elsewhere, mostly in
India. Research during this period showed that single-cross hybrids have 25-30% grain yield
advantage over OPVs. Also, during this period, there has been a gradual change in emphasis in
Indian public sector towards.................
