The lines represent progeny from four generations of kanamycin-resistant plants derived from a cross between a steriledex1 plant and a wild-type (Wassilewskija) plant. KanR, Kanamycin resistant; KanS, kanamycin sensitive. Segregation ratios are shown in parentheses.

    • F1-a  Unselected seed, not scored for kanamycin resistance.

    • F1-b  Chi- squared test 0.05 > P > 0.01; all others P > 0.05.
