Breeding way to create intensive varieties of Jerusalem artichoke (Topinambour) and Topinsa sunfl ower

Abstract

The work substantiates the necessity for accelerated breeding of new intensive Topinambour (Jerusalem artichoke) and Topinsa sunfl ower cultivars endowed with permanent heterosis, suited to modern agriculture at continuous aridization of the European climate. Corresponding to the genetic algorithms of their creation and results of practical selection are adduced. Wild Helianthus spp. from the North American Gene Centre and topinsa sunfl ower can become genes’ donors for tuber ‘optimal cork layer’ synthesis.
