HONG Yifeng, CAI Gengyuan, WU Zhenfang. Effects of genealogical errors on the reliability of ssGBLUP to estimate breeding values[J]. Journal of South China Agricultural University, 2019, 40(S1): 85-88.

This study was aimed to study the influence of genealogical errors on the reliability of estimated breeding values (EBV) obtained by ssGBLUP. Under the condition of different heritabilities, reference groups and genealogical errors, effects of ssGBLUP, GBLUP and BLUP on the reliability of EBV were evaluated. Data were simulated using QMSim software and analyzed by BLUPf90 software. The results showed that the heritability degree and genealogical error rate had nothing to do with reliability of EBV. The tolerance of ssGBLUP to genealogical errors decreased gradually with the gradual increase of reference group. The reliability of EBV obtained by ssGBLUP decreased linearly with the increase of genealogical error rate.
