Abstract

This study was conducted to study the genetic diversity among thirty pearl millet (Pennisetum glaucum L.) genotypes collected from various agro climatic regions of the Sudan using both agro morphological traits and RAPD markers. A field experiment was conducted at Sudan University of Science and Technology, College of Agricultural Studies, Shambat, during the summer season 2013. A randomized complete block design (RCBD) with three replications was used in this study. Five agro-morphological traits among thirty pearl millet genotypes included leaf area (cm²), number of tillers, plant height (cm), stem diameter/main head (cm) and to days to 50% flowering were measured. The phenotypic correlation between these traits was determined. The results showed that there were significant differences among all agromorphlogical traits. Leaf area was highly significant and positively correlated with plant height. This variation could be of a great value in any pearl millet breeding program. Based on DNA molecular markers analysis (RAPD), high level of polymorphism among genotypes was detected, indicating that the technique was efficient in determining the genetic diversity among millet genotypes, and thus could be exploited further to establish consistent heterotic group between pearl millet genotypes.
