Retransformation of a male sterile barnase line with the barstar gene as an efficient alternative method to identify male sterile-restorer combinations for heterosis breeding

We report in this study, an improved method for identifying male sterile-restorer combinations using the barnase-barstar system of pollination control for heterosis breeding in crop plants, as an alternative to the conventional line x tester cross method. In this strategy, a transgenic male sterile...
