Genetics of Qualitative Traits in Pearl Millet: A Review
- K. Anand Kumar and
- David J. Adrews
Pearl millet, Pennisetum glaucum (L.) R. Br., is the principal food cereal on 25 million ha of the drought-prone semiarid regions of Africa and the Indian subcontinent. It is also used as a forage in Australia, southern Africa, South America, and the USA, and has shown regions. Recent increased levels of breeding and genetic research, now including gene mapping, have indicated a need for a current comprehensive review of accumulated genetic information on qualitative traits in this species. The present decriptive review attempts to meet this need and reports 167 studies. since 1934, on 145 characters in 12 categories: chlorophyll deficiencies, foliage striping, leaf characters, pubescence, plant form, pigmentation, earhead characters, reproductive structures and gamete formation, sterility, seed characters, earliness and maturity, and disease resistance. Gene symbols, where assigned by authors, are listed, and the nature of genetic effects are given. Known linkages and biochemical genetic markers are also reviewed. A comsistent nomenclature system should be developed and followed in the future, and a locaton designated for the deposition of genetic stocks.
