Interspecific hybridization of diploids and octoploids in strawberry
چکیده انگلیسی

Interspecific crosses were performed among accessions of the wild strawberry species F. vesca and F. nilgerrensis and the cultivated strawberry, F. × ananassa, following reciprocal crossing. Crosses between both F. vesca species ‘Hawaii-30’ and ‘UC-01’ were successful regardless of the presence of reciprocal crossing, while crosses with ‘Whiteberry’ of the F. nilgerrensis species were not successful. In particular, intraspecific hybridization of ‘Hawaii-30’ and ‘UC-01’ in the F. vesca species produced a tetraploid plant. Although octoploid ‘Akihime’ did not cross with different species, it performed well with ‘Hawaii-30’ only through the parent seed. Progenies of interspecific hybridization between species of different ploidy, namely ‘Hawaii-30’ and ‘Akihime’, produced 12 pentaploid plants with an intermediate phenotype between the crossing parents and characterized by sterility. In addition, despite its poor hybridization, a cross-combination between ‘Akihime’ and ‘Whiteberry’ produced one pentaploid plant, which did not bloom.


► We investigated characteristics of diploid and octoploid species in strawberry.
► We performed interspecific crosses among species different polyploidy.
► We examined cross-compatibility following reciprocal crossing.
► Interspecific hybridization with different polyploidy does not perform cross-pollination well and showed many differences depending on cross-combinations.
► Pentaploid and tetraploid plants were found by interspecific and intraspecific crosses.
