Narrative

Liberty switchgrass (Panicum virgatum L.) is a lowland type cultivar that is adapted to USDA Plant Hardiness Zones (HZ) 4, 5, and 6 in the Great Plains and Midwest, USA east of 100 degrees W. longitude and potentially other regions where it has not been tested to date. It was developed for use as a perennial biomass energy crop and is the first high yielding biomass type lowland cultivar that is adapted to this region. It can produce greater biomass yields than upland or forage type switchgrass cultivars that have been developed previously for use in the region and has equivalent winter survival. It has significantly greater winter survival in its adaptation region than previously released lowland switchgrass cultivars that frequently have substantial winter damage and stand loss north of 40 degrees N latitude in the USA. Liberty has the typical lowland switchgrass phenotype but because the female parent plants in the originating crosses was the upland cultivar Summer, it has upland cytoplasm that can be identified using chloroplast DNA markers. Liberty is typically about two weeks earlier in maturity than Kanlow, its lowland male parent cultivar, and can be distinguished from Kanlow and other switchgrass released lowland cultivars by its earlier maturity and chloroplast DNA. It is 10 days to two weeks later in maturity than Summer, its female parent cultivar, and can be distinguished from Summer and other upland cultivars by its lowland phenotype. Foundation seed production of Liberty will be managed by Husker Genetics, the Foundation Seed Division of the University of Nebraska-Lincoln, Lincoln, NE.
