IDENTIFICATION OF PLOIDY LEVEL OF THE REGENERATED PLANTS BY ANTHER CULTURE IN RICE

In the regenerated plants by the anther culture of rice, panicle lengt h, plant height and glume length were measured. Only the glume length was able to separate regenerated plants into three distinct classes. T he cytological analysis of these plants revealed that the three classe s based on the glume length consisted of haploids, diploids and triplo ids, respectively. Similar results were obtained in the regenerated pl ants derived from irradiated callus. With irradiation as a physiologic al disorder, the glume length was a stable index of the ploidy level o f rice plants.
