Abstract Kentucky bluegrass (KB) ( Poa pratensis L.) is an excellent cool‐season turfgrass sod option because of its rhizomatous growth habit. There are known growth and other characteristics differences among cultivars, but little is known about the differences in germination and establishment speed, as well as differences in rhizome and sod production for turfgrass practitioners. Therefore, the objectives were to investigate the influence of 19 KB cultivars on germination and establishment speed and sod production characteristics through replicated field and controlled‐environment experiments at Kansas State University. Faster‐germinating KB cultivars reached 50% germination and 50% establishment within <8 and <23 days, respectively, compared to slower cultivars reaching 50% germination and 50% establishment in ≥9 and ≥24 days, respectively. However, fast germination speed did not always predict fast field establishment speed. Greenhouse experiments revealed differences in the number of rhizomes and total rhizome length among cultivars. Field experiments measured sod strength (maximum tensile load to tear sod [Newtons] and required work to tear sod [N‐m]) at three harvests of 9, 10, and 13 months after planting. There were sod strength differences among KB cultivars, which ranged from ∼22 to 38 N‐m of required work to tear sod and 389 to 568 N of maximum tensile load to tear sod. While KB classification systems assist in describing other KB traits (i.e., color, density, growth, and stress tolerances), they were not consistent in predicting differences in germination or establishment speed, as well as rhizome characteristics in the greenhouse or sod production differences for sod producers.
