Effect of Drought Stress on Bread Wheat (Triticum aestivum L.) Genotypes
Journal Title: Journal of Agronomy, Technology and Engineering Management - Year 2023, Vol 6, Issue 1
Abstract
Drought is one of the environmental stress factors and the most important factor limiting crop production, especially in rain-based agricultural areas. This research aimed to determine the effects of drought stress on some bread wheat genotypes and to determine drought tolerant genotypes among genotypes. In the research, 20 bread wheat genotypes were used as material. The experiment was carried out in fully controlled greenhouses belonging to the Faculty of Agriculture of Dicle University in 2022 according to the randomized blocks trial design with 4 replications. An artificial drought stress environment was constituted by irrigating the pots up to 40% of the field capacity. As a result of the research, as the plants belonging to five genotypes lost their vitality as a consequence of the drought effect, observations could not be taken and they were not subjected to statistical analysis. Among the investigated characteristics, the chlorophyll content (SPAD) value in the spiking stage, the chlorophyll content (SPAD) value in the flowering stage, the number of days spike, and the plant height were affected by the drought application at the level of 1%, while the spike height and the number of grains per spike were affected at the 5% level. It is noteworthy that line 6, which is the prominent genotype among the genotypes in terms of spike yield, is also the earliest, has the longest plant height, and is the genotype with the highest number of grains per spike.
