Wide Hybridization Between Oat and Pearl Millet.

Wide hybridization is a one of the important techniques in plant breeding. Oat (Avena sativa L.) and pearl millet (Pennisetum glaucum L.) belong to different subfamilies of Poaceae. In generally, such distant relative species show uniparental chromosome elimination after successful fertilization. However, all seven pearl millet chromosomes are retained beside the genome of oat during embryogenesis. Hybrid seedlings develop, but show necrosis after light irradiation. Here, a detailed protocol for wide hybridization between oat and pearl millet is described.
