INVESTIGATION ON ADAPTATION OF TEN BERMUDAGRASS (CYNODON SP.) CULTIVARS IN ISFAHAN ENVIRONMENTAL CONDITION

To study the adaptation of ten cultivars of bermudagrass in Isfahan. a field study using a randomized complete block design with three replications was established in Khomeinishahr. Isfahan during 2002-2003. Results showed significant difference among cultivars for measured traits. `Tifwayʹ and ʹTifgreenʹ showed excellent establishment and cover rate. Tifwayʹ, ʹ3200w19-9ʹ and `ISF2ʹ, showed highest leaf area. height and dry weight compared to others. Density of ʹISF2ʹ, `Tifgreenʹ and `Tifwayʹ was increased by the end of experiment. Evaluation of monthly average color showed that the turfgrass color was the best during July and September and the least during December to February. All cultivars showed unsuitable color in December, January and February. Also evaluation of cultivars average color showed that `Tifdwarf , `Tifgreenʹ and .1SF2ʹ were the best. However, due to significant interaction between genotypes and time, color of cultivar was depended on month (temperature). Finally. `Tifwayʹ, followed by `ISF2ʹ, showed most adaptability to Isfahan climate.
