Italic cells were zeroed for the tested hypothesis. (A) CT population: unviable gametes when homozygous for the Ryadg resistant gene resulting in segregation (1N:5S:4D). (B) TL population: unviable gametes when homozygous for the Ryadg resistant gene resulting in segregation (1N:4S)
1The Chi value is 3.8. The p value is 0.15. The result is not significant at p ≤ 0.05
2The Chi value is 2.012. The p value is 0.156. The result is not significant at p ≤ 0.05
