final disease score of each line. These values were used for analysis of variance and
F tests using the general linear models (GLM) procedure, using SAS software v.8.2
(SAS Institute, Cary, NC, USA). Broad sense heritability (h2) was
estimated according to
(1996)
genotypes, separate analyses were performed for the parents and recombinant inbred
lines. Effects of different sources of variation were considered significant by F
test when P ≤ 0.05. Skewness, kurtosis (
1970
normality tests were applied to verify normal distribution of variance analysis
residuals.
