The detection, rate and manifestation of residual sexuality in apomictic populations of Pilosella (Asteraceae, Lactuceae)
Original language description
The effect of maternal, facultatively apomictic plants on population diversity was evaluated in seven hybridizing polypoid populations, where apomictic (P. aurantiaca or P. bauhini) and sexual (P. officinarum) biotypes coexist. Due to residual sexuality,the progeny different from their maternal parents (0.6-92.3% of embryos and 0-100% of seedlings) originated either sexually or via haploid parthenogenesis. The facultatively apomictic mothers generated the progeny more variable in ploidy level than wasthe progeny derived from sexual mothers. Residual sexuality in apomicts was also effective in experimental crosses. The 2n+n hybrids produced from an apomictic and a sexual parent (both in the field and in experiments), displayed similar reproductive behaviour, producing polyhaploid, sexual and apomictic progeny in variable ratios. The variation recorded in these populations suggests introgressive hybridization towards the sexual species.
