Today pearl millet is grown on over 260,000 km
2 of land worldwide. It accounts for about 50% of the total world production of millets. Pearl millet is the most widely grown millet and is a very important crop in India and parts of Africa.
World production of millets has been stable during the 1980s. According to FAO, 39.4 million hectares of millet were planted in 1987 with an average production of only 704kg/ha.
Structure and physical properties
pearl millet varieties from the world collection probably have more variation in physical characteristics than any other millet. Kernel shape has different classifications: obovate, hexagonal, lanceolate, globular and elliptical. In Africa, pearl millet is classified as either globular or lanceolate and hexagonal. Most of the millets are very similar to each other in basic structures, although there are some very specific differences.
Composition
The mean value in proximate composition of variety Changara of pearl millet are presented in the table below. The proximate composition can be affected by both environment and genetics. Pearl millet usually has higher protein content and fat contents than sorghum or other millets because the kernel is a naked caryopsis.

A reference genotype of pearl millet (Tift 23D2B1-P1-P5) has been fully sequenced, which holds around 38,579 genes. Some of these genes are for wax biosynthesis, which is known to be involved in tolerance to abiotic stresses in pearl millet.
