The PERPETUAL FLOWERING locus: Necessary but insufficient for genomic prediction of runnerless and other asexual reproduction phenotypes in strawberry.

ABSTRACT: Strawberry (Fragaria ×$\times$ ananassa) reproduces sexually through seeds and asexually through stolons. The ability to cost-effectively clonally propagate hybrid individuals on a large scale has shaped strawberry breeding and production practices. Despite the technical and economic importance of clonal propagation, little is known about the genetic regulation of runnering in strawberry, apart from the pleiotropic effects of PERPETUAL FLOWERING (PF), a dominant gene introgressed from a wild relative that abolishes temperature-dependent photoperiod sensitivity and incompletely and variably suppresses runnering. Here, we show that runnering phenotypes are heritable and highly variable in strawberry, ranging from runnerless to prolific in short-day (pfpf) and day-neutral (PF_) plants. The PF
