Deflated preconditioned conjugate gradient method for solving single-step BLUP models efficiently

Table 2 Comparison of estimates obtained with different models against estimates obtained with ssGBLUP using the PCG method

Dataset	Model^a	Pearson correlation	Intercept^b	Regression coefficient^b
Reduced dataset	ssSNPBLUP	> 0.999	0.045	0.998
Field dataset	ssSNPBLUP	0.999	− 0.001	0.997
Field dataset	ssPCBLUP	0.999	− 0.001	0.998

^assSNPBLUP was solved with the DPCG method with five SNP effects per subdomain; ssPCBLUP was solved with one PC effect per subdomain
^bResults from the regression of estimates of ssGBLUP on estimates of ssSNPBLUP or of ssPCBLUP
