Apospory appears to accelerate onset of meiosis and sexual embryo sac formation in sorghum ovules
Background Genetically unreduced (2n) embryo sacs (ES) form in ovules of gametophytic apomicts, the 2n eggs of which develop into embryos parthenogenetically. In many apomicts, 2n ES form precociously during ovule development.

Heterosis and Expressivity of Apospory in Tetraploid Bahiagrass Hybrids
ABSTRACTBreeding procedures developed for apomictic species are based on the idea of fixing superior hybrids by apomixis. However, scarce information is available about the occurrence of heterosis in apomictic hybrids. The objective was to generate a group of apomixis‐segregating tetraploid bahiagrass (Paspalum notatum Flüggé) families, evaluate the ...

Genetic Control of Apospory in Apomictic Paspalum Species.
The genetic control of aposporous apomixis in Paspalum was investigated by determination of the reproductive mode of the progeny from a cross of the sexual, self-incompatible tetraploid, P. ionanthum by the facultative apomict, P. cromyorrhizon. One hundred and sixty-nine progeny were assessed using embryological analysis, of these, 127 were shown to ...
