Whole-genome prediction of KRN in the inbred lines. a The KRN prediction accuracy for different numbers of randomly selected tagSNPs (from 5 to 27,000) based on BLUP values by using the rrBLUP model. b KRN prediction accuracy for different training population sizes. c Comparison of prediction accuracy between the top tagSNPs and random tagSNPs. **, P < 0.01. d Comparison of the prediction accuracy of different tagSNPs identified by different models. **, P < 0.01
