We have shown how monodii (primary gene pool), a weedy Pennisetum americanum subspecies, is a valuable source of genes for resistance to the major diseases of pearl millet, a stable cytoplasmic male sterile system, restorer genes, and yield. The gene for rust resistance can significantly increase both dry matter yield and quality of forage. The secondary gene pool of P. purpureum has genes for male fertility restoration and grain yield, better fertility restoration than most genes previously reported. The interspecific hybrids between pearl millet x P. purpureum have immediate forage potential and produce high quality forage from September to December when there is a critical need for high quality forage. Male-fertile, apomictic backcrosses and bridging hybrids continue to be produced for transferring gene(s) controlling apomixis from P. squamulatum to pearl millet. The principles and techniques developed in this study have significant implications for transferring genes controlling apomixis and other characteristics from the tertiary gene pools to cultivated crops.
