Estimating the genetic value of F1 apple progenies for irregular bearing during first years of production
Keywords: alternation indices, biennial bearing, cultivar breeding, linear mixed model, Malus x domestica, QTL detection
AbstractFlowering regularity in apple trees during the beginning of their mature phase was assessed using new descriptors based on annual yields. To allow genotype evaluation at reasonable sampling costs, they were approximated using subsamples of annual shoot sequences at axis scale. The approximation provided a good discrimination between regular and alternate bearing genotypes. QTLs were detected for some descriptors.
