Differentiation of haploid and dihaploid rape plants at the cytological and morphological levels

Some cytological and morphological features of haploid and dihaploid winter rapó plants obtained via the anther cultivation approach have been studied. It was shown that in haploid plants the number of chloroplasts in stomatal guard cells, the size of the stomatal guard cells themselves were much smaller, and the number of stomata per square unit was greater than in doubled haploids and diploids. Haploids were also characterized by smaller sizes of petals and anthers and, in general, a smaller flower as compared to dihapliods and diploids.
