In 2010-2015, in Absheron SEB of the Institute of Genetic Resources and in Gobustan and Terter ZES of the Az. RIA have been studied more than 2,000 samples of di-, tetra- and hexaploid wheats, original intraspecific and interspecific hybrids. As a result of 4 expeditions in 2012-2013, from the territory of Nakhchyvan Autonomous Republic were collected 148 samples of durum wheat, compactum, interspecific hybrids and 830 genotypes of bread wheat. In addition, there was collected a sterile hybrid between wheat and Aegilops and also 2 fertile stable wheat-rye hybrids (x Triticosecale Wittm.), as well as unknown in the existing classification forms and varieties. It was revealed a wide intraspecific polymorphism on morphological, physiological and economic features in T.dicoccum, T.durum, T.polonicum, T.compactum, T.aestivum. There are of interest founded dwarf and semi-dwarf forms of T.polonicum, T.vavilovii v.rubromraviani var.nova, «vaviloid» short mutant of T.vavilovii, the original complex interspecific hybrid. The selected genotypes of tetra- and hexaploid wheats are recommended to create a trait collections and at breeding as genetic sources of wintering and frost, drought, disease and lodging resistance, high yield, grain quality.
