  • Publication number: 20210315143
    Abstract: ‘FAES1307’ is a new and distinct zoysiagrass (Zoysia japonica Steud.) variety distinguished at least by its medium leaf texture, high turfgrass quality, good drought tolerance, improved winter turfgrass color retention, and low incidence of large patch disease caused by Rhizoctonia solani anastomosis group 2-2 LP. Compared to its parents and commercial checks, ‘FAES1307’ has a shorter canopy height and is a more prolific producer of stolons. It tends to have shorter leave lengths and moderate leaf widths. Its flag leaf height is similar to its female parent, ‘FAES 5309-12’ while its flag leaf width is similar to its male parent, ‘BA 123’. The seed head heights of ‘FAES 1307’ are shorter and consistent with the height of its female parent, ‘TAES 5309-12’. ‘FAES1307’ and its parents have narrower raceme widths; and shorter raceme lengths compared to to ‘Meyer’ and ‘SS-500’.
