Abstract/Contents:"Zoysiagrass is a warm-season species, forming dense turf suitable for fairways, tees and greens. The objective of the study was to evaluate zoysiagrass for adaptation and performance on golf course fairways in Northern California. The study was planted in 2019 at two golf courses: Meadow Club, Fairfax and Napa Golf Course (GC), Napa. Sixteen experimental lines from Texas A&M University and four cultivars ('Innovation', 'Diamond', 'El Toro' and 'De Anza') were planted. The trial at Meadow Club was terminated in the spring of 2021 due to water restrictions, while observations at Napa GC continued until June 2022. 'Diamond' and experimental lines DALZ1802, DALZ1807 and DALZ1309 showed high quality and winter color retention at both golf courses. They formed dense, uniform turf, with dark genetic color. The texture of all three experimental entries was very fine, finer than 'Diamond'. These three experimental lines are interspecific hybrids between Z. matrella and pacifica (DALZ1802), Z. matrella, minima and pacifica (DALZ1807), and Z. matrella and minima (DALZ1309). It appears that very fine textured Z. minima and pacifica are contributing towards high shoot density, dark green genetic color and winter color retention in these hybrids. The establishment of all lines was slow, not exceeding 32% after 132 days after planting. Evaluation under drought stress at Meadow Club, two months after irrigation was restricted, showed that DALZ1702 and DALZ1812 retained the highest green cover. DALZ1702 also had good overall quality and low seedhead production. Both DALZ1702 and 1812 are Z. matrella x japonica hybrids which explains their superior turfgrass quality under water restrictions. Among the commercial cultivars, Diamond had good quality and retained high green cover. New zoysiagrass lines can provide a good surface for fairways in Northern California, with lower irrigation inputs and retaining green color in the winter, however their disadvantage is slow establishment."
