Evaluation of promising breeding material based on turgid and durum wheat

Abstract

The purpose of the research is to evaluate the selected breeding material from a complex combination of turgid hybrid with winter durum wheat of the Donchanka variety. The hybrid selected at the initial stage was further decomposed into red-grain and white-grain genotypes. As a result of the study, higher production characteristics of the selected hybrid genotypes are shown in comparison with the original Donchanka. The increase in the production characteristics of hybrids occurred due to an increase in the number of grains and their size. The highest yield was shown by white-grained hybrid forms, which were distinguished not only by a large number but also by a larger mass of grain from the ear. The red-grain hybrid forms differed by a slightly smaller number of grains in the ear, but their noticeable size, that is, a larger mass of 1000 grains. When crossing a previously obtained hybrid form of turgid wheat [(tur x tur) x Terra] with the Donchanka winter durum wheat variety, highly productive white-grain and red-grain genotypes were identified, which were almost 25% superior to the zoned initial durum wheat variety on such an important breeding trait as the weight of grain from the ear. The quality indicators of grain in these forms remained at the level of the original Donchanka, which makes them a very promising breeding material.
