Popis:	The inheritance of anther orientation of 154 individuals from two B1 populations of Brassica rapa (syn. Brassica campestris) was evaluated under controlled conditions in a greenhouse. The anther orientation was evaluated visually at the time of fully open flowers. The observed extrorse:introrse ratios were 1 : 1 in R-o-18 × (R-o-18 × RM29) population and 3 : 1 in R-o-18 × (R-o-18 × R c-50) population. It was concluded that this trait is controlled by two duplicated pairs of genes (A1, A2) for extrorse anthers, either of which can produce extrorse anthers when a single dominant allele is present. Introrse anthers result when all alleles at both loci are recessive.
