Fig. 2.

Combination types of 5A chromosomes in the F₂ progeny derived from CM39 × M1403 and CM39 × MM43. ‘P’ indicates parental plants. ‘F1’ indicates F₁ generation. ‘Ⓧ’ indicates selfing. ‘F2’ indicates F₂ generation. ‘Rec1’ and ‘Rec2’ indicate the 5AL arms formed by recombination in the 535–18 interval. ‘Rec3’ and ‘Rec4’ indicate the 5AL arms formed by recombination in the 119–535 interval. ‘DRec1’ and ‘DRec2’ indicate the 5AL arms formed by recombination in both 535–18 and 119–535 intervals. The number in parentheses indicates the number of seeds that contain the corresponding combination types of 5A chromosomes. The schematic representation of each chromosome is shown. Scale bar: 50 μm
