Seed source level parameter estimates
Pleiku	CF		0.04 (0.03)		0.03 (0.04)		0.04 (0.03)		0.02 (0.02)
Bau Bang			0.97 (0.04)	0.05 (0.03)	0.10 (0.61)	0.11 (0.08)	0.78 (0.21)	0.11 (0.07)	0.60 (0.23)	0.16 (0.04)

Narrow-sense heritability estimates or the proportion of variance between seed sources are given on the diagonals (bold). Type B (among trials) additive genetic and seed sources correlations are given below the diagonal. Approximate standard errors of each estimate are given in the parentheses
Notes: CF = convergence failed
