Table 2 Response to selection, R for grain yield in the training population across different selection strategies

From: Accuracy of genomic selection for grain yield and agronomic traits in soft red winter wheat

Selection strategy Grain yield (t ha −1) ± SD Variance (σ2) Selection differential, S a Response to selection, R b % change relative to PS
GS 3.61 ± 0.34 0.12 0.44 0.21 −32.3
MS 3.34 ± 0.36 0.13 0.17 0.08 − 74.2
PS 3.82 ± 0.16 0.03 0.65 0.31
RS 3.19 ± 0.36 0.13 0.02 0.01 −96.8
PS + GS 3.88 ± 0.18 0.03 0.71 0.34 9.70
  1. GS genomic selection, MS marker-based selection, PS phenotypic selection, PS + GS phenotypic + genomic selection, RS random selection
  2. a S = μsel - μpop; μpop = 3.17 t ha−1
  3. b Calculated as R = H2S where H2 is heritability for grain yield based on published value in Lozada et al. [26]; equal to 0.48
