Case study of adoption of a pearl millet variety in a non-target region uri icon

abstract

  • Cross-pollinated breeding system of pearl millet(Pennisetum glaucum), or popularly called bajra, providesfor open-pollinated varieties (OPVs) and hybrids as thetwo broad cultivars options. The International CropsResearch Institute for the Semi-Arid Tropics (ICRISAT)initially had a major emphasis on OPVs, leading to thedevelopment and release of several OPVs from itsbreeding programs in Asia and Africa. The first and themost successful among these was WC-C75 developed atICRISAT, Patancheru from a composite introduced fromNigeria. Released in India in 1982, its average grain yieldin 110 trials conducted by the All India CoordinatedPearl Millet Improvement Project (AICPMIP) in all pearlmillet growing states was 99% of that of the then mostpopular and widely cultivated hybrid BJ 104 (Andrews etal. 1985). At the peak of its adoption during late 1980s, itwas cultivated on about 1.2 million ha (Rai et al. 2006).However, a comparative study of OPVs and hybrids fromseveral 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
