The third cycle of selection for alfalfa populations with improved stem and leaf yield for use in biomass energy production system has been completed. Nearly all varieties were susceptible. 2001. Five varieties were sampled weekly for insects,diseases, plant growth and forage quality. 2007. Selected populations and crosses between the germplasm sources are evaluated with 1 5N to determine N(2)-fixation under field conditions. Alfalfa varieties were grown in row plots, clipped in July and September and undercut in early November. Pollen production in partial male sterile plants varied between anthers within a flower, between flowers on a plant, and between sampling dates. Sheaffer, L.H. The best population (MN-SWXUC) was increased and retested at four diverse Minnesota locations in 1984. With the d … The most severe cutting treatment per location was EC-30, 35 and 24 day, SE-24 and 35 day, and NE-35 day. is aserious disease of alfalfa. The red pigments, or water soluble substances associated with the red pigments, are toxic to the developing seed. Resistant cultivars were effective at reducing losses from PRR. One tetrasomic gene with complete dominance conferred resistance to R2. Plants with low levels of resistance were found in many varieties. Vogel, M.D. Iowa State University Press, Ames, IA. S...

It is a violation of national and international law to move material containing biotech traits across boundaries into nations where import is not permitted. Alfalfa is most often harvested as hay, but is … J. Results suggest genetic potential for increased manure tolerance in alfalfa and one cycle of selection for improved tolerance has been completed. Casler, J.F.S. Crop Sci. Evaluation of a new production system using alfalfa for biomass to generate electricity has been initiated. Seed Genetics Direct’s alfalfa lineup includes 4 varieties: from low lignin to widely-adapted and haylage preference to dry bale preference. GRIN System, was used to develop a core. ).Impacts(N/A)Publications, Progress 01/01/68 to 12/30/68OutputsPreliminary studies on the inheritance of resistance to alfalfa mosaic virus consisted of evaluation of S(1) progenies of 4 alfalfa clones after inoculation with each of 4 AMV isolates which had known reactions on the parent clones. For the 2021 growing seasons, growers must direct any product produced from HarvXtra® Alfalfa with Roundup Ready® Technology seed or crops (including hay and hay products) only to US domestic use. In addition, MN-SWXUC has a greater combined resistance to Phytophthora root rot, fall leaf diseases, and frost than all available nondormant varieties. Russelle, and M.A. Summer hay yields were similar for all nondormant and dormant entries. An evaluation program to select moderately dormant alfalfa for increased salinity tolerance was initiated to improve alfalfa's usefulness in remediating contaminated sites and for top dressed manure applications. 36:766-770. New uses for alfalfa in phytoremediation, the containment or removal of environmental contaminants, generated new studies to select alfalfa for tolerance to manure or waste water applications during the growing season. the industry’s first quality enhancing trait technology. selection. Preliminary results suggest genetic potential for increased manure tolerance in alfalfa. Agron. Plantings were established May 1, 1987, at locations representing Southwest (SW), West Central (WC), East Central (EC) and Southeast (SE), Minnesota. Vance, C.P., and Lamb, J.F.S. MN-SWXUC produced an additional 17% (10 lb/A) more than the unselected nondormant checks. You’re making a significant investment in alfalfa genetics, and you want them to deliver a return. J. Traits that were measured included: number of seeds/pod, seed size, seedling vigor, secondary and fibrous root scores, crown and root weight, seeding year forage yield, and fall growth score. The third cycle of The importance of the red color was not determined earlier because it usually occurred as a co-pigment with other seed color factors. Biomass and Bioenergy 30:880-891. Sava and Kelson both produced vigorous early season growth that inhibited weed establishment and reduced soil erosion. In a biomass energy production system the leaves are separated from the stems and sold as a high quality Six germplasm sources were identified that produce progenies with high levels of disease resistance, good agronomic performance, and high yield when individually crossed. L’application du marché mondial Graines de luzerne non dormantes 2020 … Alfalfa varieties are being classified for types of pest resistance in addition to yield, so that comparative varietal descriptions will be available to growers. The pollen-tube lemgths of single crosses were about l2% less than the mid-parent mean of the single crosses. SHOREVIEW, Minn. (Oct. 3, 2014) — In an effort to bring the industry’s first quality-enhancing trait to market, Forage Genetics International (FGI) announces that the reduced lignin trait will be known as HarvXtra™ alfalfa. J. A genetic study on Phytophthora resistance is being completed. Marquez-Ortiz, J.J., Johnson, L.D., Barnes, D.K., and Lamb, J.F.S. There is no rapid method to predict combining ability among germplasm sources. Increases of breeder and foundation seed were made in 1986 along w/ production of limited amounts of certified seed. Agron. Sheaffer, and D.K. These results suggest that ineffectively nodulated alfalfa would be more useful for phytoremediation of nitrate-contaminated sites than normal alfalfa varieties. J. Exp.
