A greenhouse study was conducted to determine the shade tolerance (55% light reduction) of 42 bermudagrass (Cynodon spp.) cultivars collected from the 2002 National Turfgrass Evaluation Program (NTEP). Data collection includes visual turfgrass quality (TQ), chlorophyll concentration, root length, and total root biomass. Seeded cultivars include ‘Sunstar', ‘B-14', ‘SWI-1003', ‘SWI-1012', ‘SWI-1014', ‘SWI-1041', ‘SWI-1044', ‘SWI-1045', ‘SWI-1046', ‘Arizona Common', ‘Numex Sahara', ‘Princess 77', ‘Mohawk', ‘FMC-6', ‘SWI-1001', ‘Sundevil', ‘Southern Star', ‘Riviera', ‘Transcontinental', ‘CIS-CD5', ‘CIS-CD6', ‘CIS-CD7', ‘Panama', ‘SRX 9500', ‘Yukon', ‘Tift No.1', ‘Tift. No.2', and ‘PST-R68A'. Vegetative cultivars include ‘Tift No.3', ‘Tift No,4', ‘Tifway', ‘Midlawn', ‘Tifsport', ‘MS-Choice', ‘Aussie Green', ‘GN-1', ‘OR 2002', ‘Ashmore', ‘Patriot', ‘OKC 70-18', and ‘Celebration'. Preliminary results demonstrate differences among cultivars based on parameters measured.
