Variance components analysis, estimation of heritability (h²), and distribution of analyzed infected leaf area based on greenhouse data. Analysis was performed observing different scenarios, examining the whole data set including information of all plant developmental stages (Analysis with whole data set) in contrast to single analysis of each stage. The full genotype set (n= 240) at plant stage T1 (All genotypes at plant stage T1) was examined, as well as a limited set of 40 genotypes at the plant stages of 10 days (EC 12; T1), 5 weeks (EC 19; T2), and 10 weeks (EC 25; T3). Distribution of leaf rust resistance for different sets are given by mean value and range of infected leaf area.
