haploidy

The article is a brief overview of the scientifi c heritage of professor V. S. Tyrnov (1941–2015). He was a one of the leading scientists in the fi eld of biology and genetics of plant reproduction. His research has made a signifi cant contribution to the understanding of reasons for and mechanisms of haploidy. V. S. Tyrnov was an author of original haploid production technologies in vivo and in vitro. He created a unique corn lines with heritable and non-heritable (induced) forms of parthenogenesis.

Saratov Scientific School by Biology and Genetics of Plant Reproduction Systems was formed under the leadership of Doctors of Biology S. S. Khokhlov and V. S. Tyrnov. Most of the unique research was performed in the Laboratory of Radiation and Experimental Genetics, established in 1958. Later it was transformed into the Department of genetics and reproductive biology of the Saratov State University Botanical Garden. Over the past 60 years, Saratov scientists have made a significant contribution to the development of fundamental and applied science.
