| 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... |
