Abstract

The objective of this study was to evaluate chromosome pairing and the degree of genetic relationship between elephantgrass (P. purpureum) and pearl millet (P. glaucum). Alonso and Kimber’s mathematical model (1981) revised by Chapman and Kimber (1992) was applied to three triploid interspecific hybrids. The genomic relative affinities were calculated based on the evaluations of chromosome pairing of 50 cells in diakinesis, in which univalent, ring and rod (open) bivalent and trivalent figures were quantified. The pairing relationships estimate showed that pearl millet M24 and elephantgrass BAG 75 accessions, progenitors of F94-60-01, presented the major genetic proximity among their chromosome complement.
