Abstract
PHYTOHORMONAL REGULATION OF IN VITRO FORMATION OF WHEAT ANDROGENIC STRUCTURES
Highlights
The biotechnological method of anther culture in vitro is widely used in breeding wheat programs
The ELISA data on endogenous auxin indole-3-acetic acid (IAA) content in anthers just before inoculating them on the induction medium Potato II are shown in table
The results showed significant differences of anthers of studied cultivars on the content of this hormone
Summary
The biotechnological method of anther culture in vitro is widely used in breeding wheat programs This method is based on the phenomenon of androgenesis in vitro – the formation of haploid plants from microspores, which development switches from normal gametophytic pathway to a fundamentally different one – sporophytic [3, 8, 9, 18, 23]. Materials and methods The objects were for the first time introduced in biotechnological practice spring wheat cultivars Salavat Yulaev, Zhnitsa, Duet, Skala, Bashkirskaya 26 and Omskaya 35 These cultivars demonstrate a high response in the culture in vitro and are promising for the climatic zone of the Southern Ural. Donor plants were grown in the field conditions (Ufa region)
