The results of anther culture of F 2 pollen issued from 23 single crosses are presented. A relation between the morphology of the panicle and the microspore stage was established. After cold-pretreatment (8 days at 4°C), the anthers were cultured on the callus-induction medium N6 supplemented with 1 mg 1-1 naphthaleneacetic acid. The calli were transferred to MS plant regeneration medium supplemented with 3mgl -~kinetin + 0.5 mg 1-' naphthaleneacetic acid. The induction frequency varied from 0.22% to 29% and the regeneration frequency from 0% to 144.4%, dependent upon the crosses used. On average, 27% of the plants obtained were albinos and 59% of the green plants underwent spontaneous chromosome doubling. Thirty- nine doubled haploid lines were evaluated and multiplied in the field. Lines with an excellent behaviour in upland culture conditions were selected from two crosses |
