Estimation of duration of cultivation of regenerating callus tissues of millet in vitro

The author investigated the determinants of regenerating callus tissues of millet during long-term cultivation in vitro.The way of optimization of callus tissues transfer on fresh media with adaptation of scion-rooted plants-regenerants to nonsterile conditions was developed. The formalization of dynamic characteristics in long-term cultivated in vitro regenerating callus tissues was shown, that permit to develop on this basis the quantitative models for cloning of millet plants. The formula was proposed for determination of essential number of planting to nonsterile conditions in connection with established number of plants-regenerants.
