The regenerative potential of the system was low. B. campestris has trichomes, but fails to regenerate under the conditions employed. B. oleraceae lacks trichomes, but occasionally regenerates. Out of 1,089 calli transplanted to regeneration media, one had trichomes. Nuclear analysis demonstrated the hybrid nature of the plant.
Atrazine resistance is a ct encoded trait.
The plant was atrazine resistant. When differences between the campestris and oleraceae ct. The chloroplast genome was non-recombinant. A high frequency of plants regenerated from premature pollen grains from wheat, barley and other grasses are albino. These die prior to reproduction.
