In last year's News Letter, we presented the first observations on nonparental phenotypes in selfed progeny of regenerated plants. In particular we reported the isolation of a viviparous mutant with white seedling. This mutant proved to be allelic to vp5 on chromosome 1. Evidence of allelism was obtained by crossing the selfed progeny with the progeny of plants segregating for vp5. Out of 7 such crosses 2 ears were in fact segregating for the viviparous phenotype thus confirming the allelism of this mutant with vp5.
