Fig. 4. Validation of the breeding value and delivery of target segments.
a, Introgressed target segments of Watkins in 143 Paragon NILs based on QTL prioritization. Colours of segments represent the corresponding ancestral groups (AG1–AG7) of the donor parents. b, Inset highlighting one example for chromosome 7A, showing the composition of old breeding cultivars (top, mainly composed of AG2/5) and of NILs (bottom, also containing AG1, AG3 and AG4 representation). Details on each segment are provided in Supplementary Table 31. c, Phenotypic effects (AMMI means) of the genetic substitution derived from multi-environment screening for the 127 introgressed loci on 24 traits (marked on the perimeter; for trait abbreviations see Supplementary Table 13). Percentage increase or decrease in Watkins allele effects compared with Paragon are shown according to the vertical scale at 12 o’clock. d, Count distribution along each chromosome of the number of Watkins-unique haplotypes (represented by blue bars) that were introgressed into the modern wheat (Paragon) by backcrossing.
