Table 1.
Crosses | Generation | Resistant | Susceptible | Expected ratio (R:S) | Chi-square | Pa |
---|---|---|---|---|---|---|
HS | P1 | 20 | 0 | |||
XH | P2 | 0 | 20 | |||
XH×HS | F1 | 23 | 0 | |||
XH×HS | F2 | 165 | 54 | 3:1 | 0.013 | 0.91 |
HS×XH | F2 | 81 | 32 | 3:1 | 0.663 | 0.42 |
(XH×HS)×XH | BC1 | 47 | 73 | 1:1 | 5.663 | 0.017 |
Phenotypic observations for the whole plant 21 days post-inoculation were used to determine resistance/susceptible to Gsb.
Observed segregation ratios are statistically consistent with the expected ratios (χ2 test, P < 0.05).
