Table 3.

Response to selection (R) for total yield per plant and yield components using whole marker dataset for a Bayesian ridge regression model. The top 20 selection candidates (genotypes) with the highest phenotypic value (PV) and genomic estimated breeding values (GEBV), corresponding to a selection intensity of 10%, were selected for phenotypic selection (PS) and genomic selection (GS), respectively. The top 10% selection candidates with the highest PV and GEBV from PS and GS were selected in PS + GS.
