Abstract: A new and distinctly salt and boron tolerant poplar tree cultivar named “RRR Yellow,” is particularly distinguishable by its ability to tolerate and grow in soil with high concentrations of salt, boron and selenium. The cultivar was originally discovered as a sport through stringent selection of cultivated poplar trees, and potentially from isolation of a single unique sapling or sport that exhibited high levels of salt and boron tolerance necessary for survival, and then propagated into the “RRR Yellow” cultivar.

Abstract: A new and distinct poplar clonal cultivar, Populus nigra L.×P. maximowiczii A. Henry, is described. The cultivar results from a controlled pollination using a male P. maximowiczii from Hokkaido, Japan and a female P. nigra of unknown parentage. Both named parents are unpatented cultivars. The new cultivar is characterised by a narrow crown form, dark green foliage, high resistance to leaf rusts and anthracnose, and low palatability to possums.

Abstract: A new and distinctive variety of a poplar tree, named ‘Gnarly Poplar,’ characterized by an attractive zigzag growth habit.

Abstract: A popular tree particularly distinguished by having highly figured wood is disclosed.

Abstract: A new and distinctly salt and boron tolerant poplar tree cultivar named ‘RRR Yellow’, is particularly distinguishable by its ability to tolerate and grow in soil with high concentrations of salt, boron and selenium. The ‘RRR Yellow’ cultivar was originally discovered as a naturally occuring branch sport through stringent selection of cultivated poplar trees, and potentially from isolation of a single unique sapling or sport that exhibited high levels of salt and boron tolerance necessary for survival, and then propagated.

Abstract: A new cultivar of Populus tree, ‘Prairie Skyrise’, that is characterized by its fastigate plant habit, its very dense and compact branching habit, its very vigorous growth rate, and its tendency to break dormancy early with bright green new growth.

Abstract: A new and distinct poplar tree variety, Populus, cv. ‘Gold Poplar’ is characterized by having tender yellow color leaves in the spring (Y100,C10,M5,B0), green and yellow leaves in the summer (Y100,C20,M10,B0) and gold leaves in the fall (Y100,C0,M40,B0) with a red petiole (Y100,M100,C20,B0).

Abstract: The invention is a new and distinct variety of male Populus tree named ‘NextGen’ that is characterized by its superior to above average field growth performance, its excellent to above average rooting rate, its disease resistance to foliar rusts (Melampsora sp.), leaf spots (Marssonina sp.) and stem cankers (Septoria sp.), its vigorous vegetative growth and production in nursery stoolbeds, its cold hardiness for overwintering and surviving in Minnesota with no frost damage, its wide-spread superior growth performance in many test locations (ie: MN, MI, WI, IA, IN, NY, etc); able to be considered “geo-robust” after years of testing, its replicated growth testing and evidence of promising performance and evaluation in phytoremediation research testing and applications, and its male flowers that do not produce seeds.
