Alfalfa variety development. Minnesota Agripower Project, Task II research report
This report briefly summarizes preliminary results from crossbreeding alfalfa to develop desirable characteristics for a dedicated biomass feed stock. The varieties development is part of a larger project which includes preparation and gasification of the alfalfa stems for energy production, and use of the co-product alfalfa leaves in livestock feed. The desired alfalfa traits include winter hardiness, resistance to major pathogens, resistance to foliar disease complexes, many thick, tall, solid, non-lodging stems with high lignin content, delayed flowering, and high quality leaves retained through harvest. Currently no alfalfa varieties meet these criteria. Three crosses were made using old European varieties, with thick stems, and modern resistant varieties. The crossbreeds showed some resistance to diseases, but increased resistance is needed to maximize leaf and steam yield. 1 tab.
