Pedigree - Vegetative collections of 326 bigbluestem accessions were made in Minnesota and eastern South Dakota in1985. More than 4000 individual plants were established in an evaluationnursery at the Northern Great Plains Research Lab at Mandan, ND. Evaluations in 1989 and 1990 included gridding the nursery into 4 x 6 plantplots. Two superior plants were selected in each 24 plant grid. Selectedplants in each grid were rated for phenology and separated into earlyand late maturing populations in 1990. Forage analysis was run on plantsamples collected from each of these selected plants at similar growthstages. In the late maturing population the crude protein values wereless than 6 percent. This population (9063121) contained 77accessionsfromsouthern Minnesota and extreme south eastern South Dakota. Followingestablishment of this population at Mandan, ND, seed was first harvestedin 1993. At the end of the growing season, a representative sample ofapproximately 15 grams of seed was hand stripped from each plant. Afterseveral years, all the seed was bulked into one lot. Generally, plantsof the population were tall, coarse and late maturing. Big bluestem is atall, warm-season, perennial, native grass with stiff, erect culms;flattened and keeled sheaths; membranous ligules; and flat or foldedleaf blades. Big bluestem has developed a very efficient spreading rootsystem which may reach depths of 5-8 feet in northern latitudes. Bigbluestem is composed of many ecotypes with a wide adaptation to soil andclimate.PI 635104. Andropogon gerardii VitmanUncertain. 9063122.
