Abstract

Tramp-tolerance characters of C299 of Cynodon dactylon (L.) Pers. and two hybrids ‘Tifdwarf’ and ‘Tifgreen’ of C. dactylon×C. transvaalensis Burtt-Davy were evaluated under the light-tramp, medium-tramp and serious-tramp with a 75 kg tramper. The results indicated that tramp caused leaf blades of C299 narrower, color lighter and turf quality lower; but the turf height and internode length of C299 with different rolling intensity were not obviously different from that of ‘Tifgreen’. The turf quality of C299 under serious tramp is higher than that of ‘Tifgreen’ and ‘Tifdwarf’. C299 had stronger ability to recover in vertical direction than that of ‘Tifgreen’ and ‘Tifdwarf’ under the tramp. The results show that C299 has the high turf quality and tramp tolerance charater.
