The efficiency of selection lines summer wheat in conditions of the Republic of Tuva

The results of the researches which have been carried out in 2012-2014 were submitted in Tuva research institute of agriculture according to the technique of realization of field experiences. The urgency of researches is caused by the necessity of creation new highly productive of early grades summer wheat, adaptive to the natural-climatic factors of Republic of Tuva, capable of more effective using bioclimatic resources of region. The purpose of scientific research was to study varietal distinctions in the formation of productivity of new selection lines summer wheat and establishment of their adaptive ability to conditions of a sharp-continental climate of Republic of Tuva. The research included revealing the distinctions in height of plants, formation of elements of stmcture of a crop and their efficiency. The authentic direct correlation communication (r=0,99) between a level moisture and efficiency of selection lines in conditions of Republic Tuva was established. As a result of 32 selection lines study are were selected lines (Vera*SkPG) * (SK*New67x), Rock BR x Kantegirskaya 89; Chagytai x Irtyshanka 10; Chagytai x 38/1; GK- 276 X Novosibirsk 29, 1374- E -02self 7201x-02, 1309- E -02 x H29, having a number of economically-valuable attributes most adapted to natural-climatic conditions of the region and representing the special interest for their further inclusion in selection process as a source of high productivity and stability to biotic and abiotic stresses.
