Abstract
The invention relates to a method for the production of a set of seeds which are genetically identical to the male gametes from which they arise, which may comprise placing a limited number of paternal gametes that have the form of tetrads or dyads on the stigma of a flower to fertilize maternal egg cells to obtain a number of zygotes; and inducing the loss of maternal chromosomes from the zygotes to obtain a seed set containing a limited number of seeds in which the maternal chromosomes are absent. In a preferred embodiment the father plant exhibits suppression of chromosome recombination or second division restitution (SDR) during meiosis.
