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

Some cytological and morphological characteristics of haploid and dihaploid plants of winter rape obtained via anther culture were studied. It was shown that in haploid plants the number of chloroplasts in stomata guard cells and the size of the stomata guard cells themselves were much smaller, and the number of stomata per unit area was greater than in doubled haploids and diploids. Haploids were also characterized by a smaller size of petals and anthers, and in general, a smaller flower compared to dihaploids and diploids.
