Genotype‐Environment Interactions of Bermudagrass Forage Yields

(...) The forage yields of three cultivars and 21 experimental stains (genotypes) of bermudagrass, Cynodon dactylon (L.) Pers., were determined for 3 yr (1981-1983) at five sites. These data were used to estimate and compare methods of analysis of GE interactions and yield stability in this perennial crop. First harvest (second and third years only), regrowth, and seasonal total dry matter forage yield data were analyzed. (...)
