Результаты селекции яровой твердой пшеницы (Triticum durum Desf.) на скороспелость в условиях северо-востока Беларуси

Abstract

In conditions of the Republic of Belarus we have created and estimated new gene complex of spring hard wheat. We have realized and examined hybridization of varieties of Triticum durum Desf. We have obtained valuable gen- otypes, which are adapted to the region conditions, have high productivity and quality of grain and meet the require- ments of food industry. We have created valuable selection material for obtaining native competitive varieties of spring hard wheat. On the basis of conducted research we have developed theoretical bases for selection of spring hard wheat for Belarus: we have established correlation dependence of productivity and grain quality on meteorological factors in certain inter-phase periods of plant development; we have established variety peculiarities of reaction to changing en- vironment, which should be taken into account when creating adaptable varieties; we have selected sources according to economically-valuable signs and given estimation of selections efficiency with spring hard wheat in Belarus.
