ScABI3 segregation analysis and parental germination testing was performed on intact seeds after-ripened for 6 weeks and treated with 2 µM ABA. ScABI4 segregation analysis and parental germination testing was performed on half seeds after-ripened for 3 weeks and treated with 5 µM ABA. Germination percentages after 112 h of imbibition are shown for ScABI3, and germination percentages after 48 h of imbibition are shown for ScABI4
Chi-square values calculated based on a hypothesis of incomplete dominance. Calculations were based on parental percentages using the midparent value to estimate germination of the heterozygous state
