Genomic selection
Genomic selection for improved heat stress tolerant populations and lines
Six multi-parent synthetic populations were formed for genomic selection for heat stress tolerance. Each population involved 8 to 12 CIMMYT-Asia adapted lines (heat tolerant donor lines and CIMMYT Asia elite lines) (Table 1). The S2:3 families from each of the population were genotyped with 300 to 400 polymorphic SNPs and their test crosses were evaluated at multiple heat stress environments across South Asia. The genomic selection scheme followed in the project is detailed below Table 1: Lines involved in Multi-parent synthetic formation
