Fig. 10. Segregation of size Characters. At left Nicotiana rustica brazilia. This plant was crossed with N. rustica scabra shown at left in Fig. 11. At right is a segregate of the second hybrid generation which is exactly like its parent. Unfortunately it has branched at the base or the similarity would be more striking.

Fig. 11. Segregation in size Characters. At left Nicotiana rustica scabra. This plant was crossed with N. rustica brazilia shown at left in Fig. 10. At right is a segregate of the second hybrid generation exactly like its parent in size of plant, leaf and flower and in habit of growth.
