Characterization of ICRISAT-bred Pearl Millet Restorer Parents uri icon

abstract

  • Pearl millet (Pennisetum glaucum (L) R. Br.), primarily grown for grainproduction on more than 26 m ha in the arid and semi-arid tropical (SAT)regions of Asia and Africa, is a highly nutritious cereal crop with wideagro- ecological adaptation. India, the largest producer of this crop at theglobal level, cultivates pearl millet on about >9 million ha contributingto more than 90% area of the crop in the Asian region. It is a highly crosspollinated crop, and single-cross hybrids generally give 20-30% moreyield than open pollinated varieties (Rai et al. 2006). With the availabilityof commercially exploitable cytoplasmic-nuclear male sterility (CMS)systems in pearl millet, the national agricultural research system (NARS)and the private seed sector in India focused their breeding programson hybrid development. This led to the development and adoption ofa diverse range and large number of hybrids (> 80 in 2011) and nowoccupying > 4.5 m ha area, which is about half the total pearl millet areabeing cultivated in India (Rai et al. 2006). ICRISAT also aligned its breedingprogram to developing promising hybrid parental lines in order to supportthe Asian pearl millet hybrid program
