Abstract

Cross-pollinated breeding system of pearl millet (Pennisetum glaucum), or popularly called bajra, provides for open-pollinated varieties (OPVs) and hybrids as the two broad cultivars options. The International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) initially had a major emphasis on OPVs, leading to the development and release of several OPVs from its breeding programs in Asia and Africa. The first and the most successful among these was WC-C75 developed at ICRISAT, Patancheru from a composite introduced from Nigeria. Released in India in 1982, its average grain yield in 110 trials conducted by the All India Coordinated Pearl Millet Improvement Project (AICPMIP) in all pearl millet growing states was 99% of that of the then most popular and widely cultivated hybrid BJ 104 (Andrews et al. 1985). At the peak of its adoption during late 1980s, it was cultivated on about 1.2 million ha (Rai et al. 2006). However, a comparative study of OPVs and hybrids from several AICPMIP trials showed that hybrids, in general, give 25–30% more grain yield than OPVs (Rai et al. 2006). Thus, as more productive hybrids were produced, WC-C75 was gradually replaced.
