  • *Mean chromosome number calculated for each generation by averaging subsampled plants within lines, and these values were averaged across all lines.

  • Percentage of aneuploid plants in generations S0:1 to S5:6 was determined using FISH mixture 1 (SI Materials and Methods), and the percentage of aneuploid plants for the S10:11 generation was determined using mixtures 1, 2, and 3.
