Arabidopsis hybrids and allotetraploids. (a) Seedlings of the F1 hybrid produced by crossing Arabidopsis thaliana Columbia × A. thaliana C24. (b) A stable allotetraploid (in F8 generation) was maintained by self-pollination. (a) and (b) were reproduced from [101] with permission. The F1 interspecific hybrid or allotetraploid was produced by pollinating A. thaliana Ler autotetraploid with pollen from the outcrossing A. arenosa tetraploid [48, 132]. (c) Typical flowers of the allotetraploid and its progenitors, A. thaliana tetraploid (inset, diploid) and A. aresona. (d) Seeds of the allotetraploid and its progenitors, A. thaliana Ler tetraploid and Arabidopsis arenosa. Seeds of A. thaliana Ler diploid are also shown.
