Interpretive Summary:

Technical Abstract: As a high polyploidy, apomictic, self-incompatible, perennial grass, Kentucky bluegrass has such complex genetic architecture that conducting standard Mendelian genetic selection is currently impossible. One large hurdle is the inability to differentiate true hybrids from other apomictic progenies. In this report, we show hidden molecular variation in putatively apomictic cultivars, and then the use of DNA markers to identify true hybrids.
