Fig. 3From: Genetic basis of the very short life cycle of ‘Apogee’ wheatInteractive effects of flowering genes. a Interactions between vrn-A1 and VRN-B1. Plants are classified into four genotypic classes and compared for flowering time, dominant vrn-A1a and dominant Vrn-B1, dominant vrn-A1a but recessive vrn-B1, recessive vrn-A1b but dominant Vrn-B1, and recessive vrn-A1b and recessive vrn-B1. b Interactions between vrn-A1 and vrn-D3. All plants are classified into four genotypic classes regardless of allele status of VRN-B1 or PPD-D1. c Interactions between vrn-A1 and vrn-D3 in the presence of recessive vrn-B1 allele. All plants that have dominant Vrn-B1 allele are classified into four genotypic classes and compared for flowering time, dominant vrn-A1a and dominant vrn-D3a, dominant vrn-A1a but recessive vrn-D3b, recessive vrn-A1b but dominant vrn-D3a, and recessive vrn-A1b and recessive vrn-D3b. d Effects of PPD-D1 under different genetic backgrounds. Spring indicates the dominant allele for vrn-A1a and Vrn-B1, and winter indicates the recessive allele for vrn-A1b and vrn-B1 Back to article page
