YR_Aud yellow rust area under disease progress curve (AUDPC), SR_Aud stem rust AUDPC, TKW-thousand kernel weight, GY grain yield, SS number of spikelets spike⁻¹, DH days to 50% heading, PH plant height, SL spike length, KS number of kernels spike⁻¹, BM biomass, HI harvest index, SE standard error, Rank-performance of the checks when ranked from the best to the worst performing genotype (n = 168). DH and PH was ranked from the earliest to the latest and from the shortest to the tallest, respectively, SL, SS, KS, TKW, MKW, GY and BM were ranked from the highest to the lowest while YR_Aud and YR_Aud were ranked from the least value (most resistant) to the highest value (most susceptible).
