38 min temu · Here, we present a method to identify causal genes for seed dormancy QTLs in barley by a map-based cloning method using progeny test by following procedures. We grow a mapping population derived from the cross between parents with different alleles on target QTL. We collect seed and DNA samples for dormancy evaluation and genotyping.
