Abstract: | Interspecific hybrids from the crossing Brassica campestris x B. hirta are reported in our study for the first time. F1 plants were obtained by using ovary culture. The phenotype of hybrids was similar to B. napus; the plants were self-fertile. Investigation of meiotic division and nuclear DNA content measurements showed the amphidiploid origin of these hybrids. The relationship between genome A and D, as well as the spontaneous amphidiploidization of the hybrids, are discussed. |
