18WCPP is the first trial to fully embrace the utilization of the CPF methodology. This new and novel approach to turf evaluation allows TWCA to report both the minimum threshold for qualification and the performance of all cultivars that did not meet or exceed that threshold consistently.
Reported in the public data tables available on tgwca.org is the CPF threshold for qualification (reported as a consistent default 1.10 score for all qualified cultivars) and the actual Cultivar Plant Factors for cultivars that did not qualify.
Some cultivars are reported as redacted for their values due to a lapse in membership. If the trialing fees or membership dues are renewed the trial data for those cultivars is available for review and release.
With a growing list of qualified cultivars available for non-exclusive production; seed producers can ramp production immediately and possibly even share production with other TWCA members through a new non-exclusive licensing program withing the TWCA. This program, available to non-members through a licensing agreement utilizing a flat fee and 1%/grower price royalty makes puts these and similar qualified products within reach of every seed producing company regardless the capacity to carry membership or sponsor cultivars into trialing.
While 18WCPP concludes the largest trial TWCA trial yet other trials continue at full pace. Current TWCA trial activity includes 20WCFA currently running in ten locations across North America. Upcoming trialing includes 24WCLP.
