Abstract
Perennial ryegrass (Lolium perenne L.) is a highly valued species both for agriculture and amenity purposes. However, it lacks winter hardiness for cultivation at certain regions. As winter hardiness is a very complex trait which is affected both by numerous environmental conditions and genetic composition of a plant, freezing tolerance is an important component of winter hardiness. The freezing tolerance at the population scale might be determined at selected fixed-temperature points or by the LT50 evaluation. Here the LT50 value evaluation has a potential to reveal substantially more information about this trait, as it involves assessment of survival at a series of freezing temperatures. Herein we present a high-throughput freezing tolerance evaluation method for perennial ryegrass populations.
