Table 5.
Percent of seedlings with certain morphotypes and polyembryony 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 seedlings. Symbols: ♀—female recipient; ♂—male donor.
