The long juvenile period (LJP) characteristic of soybean (Glycine max L. Merrill) cultivars delays flowering under short-day conditions. This trait may be important in increasing the adaptation range of soybean to low latitudes and provides greater flexibility for sowing times within the same latitude. The inheritance of the long juvenile period was studied in the MG/BR22 (Garimpo) soybean cultivar to provide knowledge to support the development of cultivars adapted to short day conditions. Four cultivars (?Paraná?, ?Bossier?, ?Bragg?, and ?Davis?) were crossed among each other and with MG/BR 22 (?Garimpo?). The study was conducted under short-day conditions (early sowing) in a greenhouse and in the field, in Londrina, Paraná, (23°22? south latitude). The parents and the F1, F2, and F3 populations were assessed daily for flowering. The genotype ratios of 15:1 (p > 0.95, c2 test) and 8:7:1 (p = 0.193) for the F2 and F3 generations, respectively, obtained for the Paraná x Bossier cross indicated a case of digenic interaction with a duplicate recessive epistatic effect for the LJP character. Segregation of the F2 population from the MG/BR 22 (Garimpo) x Paraná cross resulted in the expected ratio of 3:1 (p = 0.166, indicating that the MG/BR 22 (Garimpo) and Paraná cultivars differed at a single locus. Similarly, in the MG/BR 22 (Garimpo) x Bossier cross, a 3:1 (p = 0.065) segregation indicated that these two cultivars differed at a single locus for number of days to flowering. The Davis cultivar had the same gene for LJP as the Paraná cultivar (aa). The F2 segregation of the classic flowering Bragg with MG/BR 22 (Garimpo) cross resulted in a 15:1 (p = 0.138) ratio, indicating that these two cultivars differed at two loci for flowering. The genotypes assigned to the cultivars were aaBB for Paraná, AAbb for Bossier and aabb for MG/BR 22 (Garimpo). A single locus in recessive homozygosis does not produce LJP.
