Abstract
In this study, wheat genotypes with different characters were tested in different environments (arid, irrigated, waterlogging and KI application) and the responses of the genotypes to these conditions in terms of different parameters were determined. Altay 2000, Nacibey, Müfitbey, Gerek 79, Bezostaja-1 genotypes were used in the experiment. In the experiment, plant height, leaf area index, chlorophyll a, chlorophyll b, grain weight/spike, yield, grain yield, SOD, POD and proline measurements were made. Yield and yield components in wheat are largely under the influence of the environmental conditions. Bezostaja-1 and Altay 2000 genotypes were determined as stable and high performance cultivars best adapted to changing environmental conditions. While the most effective yield factors on grain yield were determined as plant height, chlorophyll a and b, grain weight/spike and LAI, SOD POD and proline were determined to be effective parameters in showing the effect of drought. It has been determined that KI application is a very effective method in identifying drought-resistant plants in irrigated conditions and gives very good results in imitating drought. In addition, drought and waterlogging are important inhibitory stress environments in plant growth. Besides, heritability of LAI, grain weight, chlorophyll a, chlorophyll b plant height, grain yield, SOD, POD and proline were found to be so low and under effect of environmental conditions.
