INFLUENCE OF VARIOUS PHYSICAL PARAMETERS ON ANTHER CULTURE OF BARLEY

This study describes the effect of some parameters on anther culture of barley to optimize the plant regeneration condition of this species. The embryo formation and plant regeneration from anthers of three barley cultivars (‘Igri’, ‘Saida’ and ‘Libya’) were investigated. The effects of length of flag leaves, stage of microspore development, and pre-treatments (mannitol or cold pre-treatment) of anthers were investigated. Results showed significant responses. Anthers at the mid uninucleate to mid-late uninucleate stage gave the best anther culture response showing 80, 60, and 30% anther development in ‘Igri’, ‘Saida’ and ‘Libya’ barley cultivars, respectively. The use of mannitol (0.3 M) or 20 days cold pre-treatments showed the best results for embryo and green-plant production.
