Title: Developing Association Mapping in Polyploid Perennial Biofuel Grasses: Final Technical Report

This project had six objectives, four of which have been completed: 1) Association panels of diverse populations and linkage populations for switchgrass and reed canarygrass (~1,000 clones each) were assembled and planted in two sites (Ithaca, NY and Arlington, WI); 2) Key biofeedstock characteristics were evaluated in these panels for three field seasons; 3) High density SNP markers were developed in switchgrass; and 4) Switchgrass association panels and linkage populations were genotyped. The remaining two original objectives will be met in the next year, as the analyses are completed and papers published: 5) Switchgrass population structure and germplasm diversity will be evaluated; and 6) Association mapping will be established and marker based breeding values estimated in switchgrass. We also completed a study of the chromosome-number variation found in switchgrass.
