INFLUENCE OF SOURCE MATERIAL FROM TRITICUM TURGIDUM L. ON THE PRODUCTION INDICATORS OF WINTER DURUM WHEAT B.V.

Representatives of Triticum turgidum L. stand out for their high productivity. In many species, the ear is large and multi-dimensional, which has a positive effect on the potential of their productivity. In addition, the characteristics of T. turgidum L. (AuB, 2n=28) are very similar to durum Desf durum wheat. (AuB, 2n=28). On the basis of some of its varieties, winter varieties have been created, which are used, as well as representatives of durum wheat, in the production of raw materials for the pasta industry. The paper presents quite productive and contrasting in their morphological characteristics varieties of turgid wheat, available in the collection of species of the FSBSI FSRCR (Federal state agrarian research center of Rostov). Created as a result of crossing the loose-billed and multi-grained varieties of var. martensii with dense-spined coarse-grained var. salomonis new hybrid forms were characterized by a high weight of grain per ear, which characterizes the productivity of the plant as a whole. According to this indicator, they significantly exceeded the modern production varieties of winter turgid and durum wheat. Since the resulting hybrid forms were quite tall, they were crossed with a relatively low-growing known variety of turgid wheat Terra. As a result of the combination [(T. turgidum loose-leafed x T. turgidum dense- leafed) x Terra], the same short-stemmed, but more productive than modern varieties, initial genotypes of turgid wheat were created. In the second generation, among the relatively short- stemmed forms obtained, elite plants with higher production indicators were selected. As a result of the combination [(T. turgidum loose-leafed x T. turgidum dense-leafed) x Terra], the same short- stemmed, but more productive than modern varieties, initial genotypes of turgid wheat were created. In the second generation, among the relatively short-stemmed forms obtained, elite plants with higher production indicators were selected. When crossing one of these selected hybrid genotypes with varieties of zoned winter hard wheat Donchanka and Kurant, it was possible to increase the production indicators of the latter.
