Description
Hybridisations among Atyloslaalbicans (twining shrub),A.scarabaeoides species (herbaceous creeper) and A. cajanlfolia (erect shrub) were carried out. The interspecific cross A. albicans x A. scarabaeoides and trispecific cross (F1 of A. albicans x A. Scarabaeoides) x A. Cajanifolia manifest forage potentially through their various morphogenetic types, erect with profuse branching and high leafiness, semi-erect coupled with profuse branching, semi-erect bushy, and spreading with broadleaves. These hybrids possess desirable gene combinations for tolerance, persistence, vigour and productivity which constitute important attributes for their adaptive fitness in tropical grasslands. Although the 3 Atylosia species were morphogenetically divergent from one another, cytomorphogentic invegtications of their hybrids revealed a high degree of chromosomal homology among them. Some of the hybrids, even though less fertile, are important for forage legumes because of their perennial nature and high vegetative vigour.
