Table 4.
Number of seeds and rates of seed germination from open cross-pollination experiment of plants originated in homoploid (diploid × diploid) and heteroploid (tetraploid × diploid) crosses. The data on species and on experimental crosses were derived from [4]. The species marked with an asterisk (*) reproduce by apomixis [4]. The number given in parentheses (#) represents the number of germinated seeds. Symbols: ♀—female recipient; ♂—male donor.
