Abstract
Relevance and methods. The study included 32 local (materials from the “Grain and Grain and Bean Crops” department of the Institute of Genetic Resources of ANAS) and 25 CIMMYT (International Center for Corn and Wheat Improvement).In total, 57 (Triticum aestivum L.) soft wheat varieties which belong to autumn were irrigated under field conditions and the amount of chlorophyll in leaves under drought conditions was based on the Inada method (Inada, 1965. Minolta, 1989).The effects of stress factors on physiological processes, especially drought on chlorophyll a and chlorophyll b depression, were investigated using SPAD 502 Plus (Spectrum Technologies, USA) in the condition laborotory.At the same time, the amount and a / b ratio of chlorophyll (a + b) were calculated and diagnostic methods were evaluated for the drought tolerance stress of the samples.
Results. As a result of the study, 21 wheat samples from 57 wheat samples in the field condition (16 local, 5 introduced), and 25 samples in laboratory conditions (13 indigenous, 12 introduced)were shown drought tolerance. Generally,there have been observed an increase in the amount of chlorophyll while study amount of chlorophyll on the sail leaves of the wheat plant with SPAD meter in laboratory conditions13 genotypes showing drought tolerance. These examples are Birlik (AZE), Durdane (AZE), Mirbashir 128 (AZE), Taraqqi (AZE), Akinchi 84 (AZE), Giymetli 2/17 (AZE), Sheki 1 (AZE), Murov 2 (AZE), Gobustan. (AZE), MV06-02 (HU-MV), TX96V2847 (US-TX), Sonmez (TR-ESK), SG-S1915 (CZ) selected for their resistance to drought stress and from these samples in the selection work on the continuity and they are also recommended to use as a starting material.
