The outcome of hybrid seeds was evaluated for each combination of crosses. Reciprocal classes of F1 hybrids were compared for pollen and seed fertility and quantitative traits including seed productivity, total biomass etc. Pollination of accession VIR320 with two accessions resulted in hybrids with drastically reduced leaves and pigmentation, resembling known cases of conflict of the nucleus and plastids. Four pairs of reciprocal F1 hybrids showed strong differences in male and female fertility, supposedly a milder manifestation of cytonuclear conflict. Male and female fertility of hybrids correlated with each other, the former appearing more convenient for evaluating genetic disturbance of gametogenesis. Only two hybrid classes showed fully fertile pollen. Some of the accessions studied have been previously reported to differ in a reciprocal translocation and their hybrids were expected to have half-sterile pollen.

Generally, strong and usually asymmetric cases of incompatibility manifested in the drop of fertility were revealed and their pattern did not correlate with phylogenetic relatedness of the accessions.
