The plant size and the spine characteristics of the first generation progeny obtained through the cross-pollination of different genotypes of Cactaceae
The main characteristics (plant diameter, number of spine/areoles and length of spines) of 16 cactus hybrids were analysed and the genetic variability and broad-sense heritability was studied. The descendants were obtained through a cyclic cross-pollination pattern, with the parental forms chosen based on aesthetic considerations. Cross-pollination among Rebutia senilis × Aylostera muscula, Rebutia tarvitaensis × Aylostera muscula, Aylostera flavistyla
