r g, cross-validated standardized accuracies of prediction. Cross-validation was based on data from POP-A and POP-B tested across 15 environments for grain yield (GY) and thousand kernel weight (TKW), 16 environments for test weight (TW), 11 environments for falling number (FN), and 10 environments for protein content (PC) and soluble pentosan content (SPC). Devln, natural logarithmic transformation of deviation variance; QTL, number of stable QTLs detected; Chr., chromosome; Pos., chromosomal position of the QTL detected; R 2, percentage of phenotypic variance explained by the detected QTL.
