Direct shoot organogenesis (DSO) on  Antirrhinum majus  L. (snapdragon) was evaluated in vitro to determine the inheritance of genes conditioning this response. One-centimeter-long hypocotyls excised from 2-week-old seedlings started in vitro in the dark on Murashige and Skoog medium served as explants. Optimal conditions for DSO on explants included hypocotyl excision from 10-day-old seedlings, 2.22 μmol BA in the culture medium, and a 21-day culture duration. An adventitious shoot was counted once it developed a stem terminated by at least one leaf appearing to have originated from an apical meristem. Seven populations were evaluated for DSO: parent 1 (P 1 ) with lowest DSO (0.3 shoots); parent 2 (P 2 ) with highest DSO (13.9 shoots); F 1  (P 1  × P 2 ); F 1  (P 2  × P 1 ); F 2  (self-pollination of F 1 ); P 1  × [P 1  × P 2 ]; and P 2  × [P 1  × P 2 ]. P 1  and P 2  were chosen as parents based on DSO counts being lowest and highest, respectively, of inbreds evaluated. DSO appears to be a trait under nuclear genetic control. High DSO appears to be dominant over low DSO. The trait appears to be simply inherited through one or two genes.
