Unfortunately, no cultivated crop displays a sufficient degree of apomixis for practical application, and only a few crop plants have wild relatives that are near-obligate apomicts.
Because of its mode of reproduction and unusually large nuclear genome, it is speculated that its success as a weed could be attributed, in part, to its behaviour as an autopolyploid apomict.
Using two highly variable microsatellites (heterozygosity H = 0.615-0.616), we show that this species is an apomict with rare sexual reproduction events that account for 0.5% of seeds pollinated in the wild.
Gametophytic apomicts differ from sexually reproducing plants in that they produce unreduced embryo sacs.
Progeny tests employing molecular markers allow the identification of individuals originated by sexual means among the offspring of a facultative apomict.
