Summary

New productive variants (PV) with physiological and morphological characters distinctly different from their original counterparts (OR) were isolated under disruptive selection in Brassica campestris cv Brown Sarson. Two new breeding approaches were tested—mating (PV × OR) F1 lines with selected cultivars, and mating disruptive with two-directional selection lines. The resulting superior three- and two-way hybrid populations, when advanced through large-scale inter-mating, produced double the yield potential of the existing controls. The genetic principles behind these breeding approaches are discussed.
