Abstract
Relevance. The current paper has presented the study results of the effect of arid growing conditions on water deficit and foliage pigment (chlorophyll) of winter wheat varieties with various productivity.
Methods. The study was conducted in 2017–2019. The objects of study were the winter durum wheat varieties ‘Eyrena’, ‘Yubilyarka’, ‘Yakhont’, ‘Yantarina’, ‘Oniks’, ‘Lazurit’ developed in the FSBSI “Agricultural Research Center “Donskoy”. There have been used such methods in the current study as the testing of varieties on drought tolerance in conditions of simulated drought (“zasushnik”) proposed by V.V. Maimistov (1988); the method of identification of chlorophyll content in winter wheat leaves proposed by I.G. Shmatko (1976); the method of identification of residual water deficit proposed by L.S. Litvinov (1988).
Results. According to the study results there have been identified the most stable, productive winter wheat varieties ‘Yantarina’ and ‘Lazurit’, which possess mechanisms of adaptation to the water stress conditions. The varieties ‘Yantarina’ and ‘Lazurit’ also possess large productivity and chlorophyll content, as well as the smallest rise of residual water deficit in the increasing aridity with 169.7 and 159.5 g/m2, 1.4 and 1.9 mg/100 g of raw weight, 24.6 and 25.7%, respectively.
