Repeated pollinations of sorghum lines with pre-germinated pollen from inbred maize lines resulted in large de novo variation in F2. Though the phenotypes of all the plants were biased towards sorghum, traits of maize such as leaf anatomy and morphology were observed in some of the crosses. RAPD marker analy-sis of the derivatives in advanced stages of generation showed maize-specific bands. It was interesting to note that diverse types of sorghum emanated from a single cross. We present the stable inheritance of vari-ation, thus introducing agronomically superior, novel, pre-breeding lines for sorghum crop improvement through incompatible pollinations.
