Two hundred and ninety-six F3 families, including two
parents in three replicates, were inoculated with pathotype,
P7.2. The score of five plants from each F3 families was
averaged, and the mean scores in replicates were used in
analysis. The results of blast disease evaluation of F3
families are shown in Tables 2 and 3. Chi-square tests of
data obtained from segregation of resistance of different
gene models, i.e. two-independent-gene model and/or two
locus interactions, showed that the expected number of
resistant and susceptible plants in the segregation ratio for a
single dominant gene model was not significantly different
from the number of observed resistance and susceptible
plants and fitted the 3:1 segregation ratio at the p≤0.05
significance level.
