Chlorophyll Content Variation in Wheat Genotypes Planted in Semi-Arid Region

Abstract

To achieve better productivity and fill the shortage caused by population increase and decrease of current wheat genotypes productivity. As a part of many studies, this study came to distinguish 21 wheat genotypes about their chlorophyll content in comparison with 3 local varieties eventually electing the superior genotypes in chlorophyll content and associated with high yield which are suitable for arid and semi-arid areas. Functioning chlorophyll enables crops to maintain photosynthesis capacity for a longer time after anthesis under the condition of water and heat stresses and this leads to longer grain filling periods and eventually higher yield. All wheat genotypes (24 genotypes) were planted according to RCBD in a research station of the College of Agriculture/ University of Anbar, western IRAQ. The findings of this study indicated genotypes with high yield and have considerable chlorophyll content, especially after flowering including “4, 6, 7, 9, 29, 31, 39, 41” and therefore can be nominated for plant breeding programs. In addition, those genotypes can be used for production in the region of western Iraq. Further studies and investigations are required to reach considerable stability in those genotypes.
