Diversity and Utilization of Pearl Millet Germplasm uri icon

abstract

  • The greatest number of cultivated, wild, and weedy forms of pearl millet occur in tropical Africa where the crop was domesticated. ICRISAT collection is over 17000 accessions, of which over 10000 are authentic landrace accessions from 42 countries. With better screening methods available to identify desirable traits from such a large germplasm collection, use of genetic resources should expand1862and contribute to broadening the genetic base of the crop. Geographic variability occurs for all characters of interest to breeders. Preliminary studies have helped to identify regions of maximum diversity, and to provide guidelines to group accessions for their effective utilization. Intercrossing, selfing, and pooling are techniques to maintain accessions and increase seed. The merits of each are discussed and formation of trait-specific gene pools is advocated as a convenient system. Conditions for seed storage are described. General guidelines for the choice and use of accessions for breeding are outlined, and examples are included
