genus onobrychis is an important forage crop consisting of approximately 130 annual and perennial species. the present research focused on the cytological studies of embryogenic (e) and non-embryogenic (ne) callus as well as root meristem cells of in vitro and in vivo grown plants. on the contrary to the previous studies, a diploid viciifolia variety with 2n= 2x= 16 chromosomes was observed for...

The present study reports the chromosome number and meiotic behaviour of 14 populationsbelonging to four taxa of Anchusa subgenus Buglossum Gusul. from Iran. All populationsshowed the chromosome number 2n= 4x= 32. It is the first meiotic study for A. subg.Buglossum. We discuss some habit form and evolutionary aspect in the light of cytogeneticdata. The origin of polyploidy (auto-allopolyploidy)...
