2011 Annual Report 1a.Objectives (from AD-416) Increase soybean yield in MG-II to IV by incorporating high-yield genes from diverse introduced soybean lines. 1b.Approach (from AD-416) The objective will be achieved by making crosses with 25% or higher plant introduction pedigrees to elite soybean lines from northeastern USA. The breeding lines will be advanced and tested against high yield checks. High performing lines will be released as germplasm or cultivars. Conventional and molecular assisted breeding will be used. 3.Progress Report This three year project started from April 2011. The advanced breeding lines from the cross of Ohio elite lines and G00-3213 selected in 2010 yield trial have been planted in four locations in Ohio for yield trial 2011. 150 lines selected from plant rows in 2010 were planted for yield evaluation in a two replicate study in 2011. Lines from 20 other crosses are being advanced by single seed decent. Ten more cross combinations were made during the summer of 2011. This research relates to objective 4 (Develop soybean germplasm with high-yield and high seed-protein content) of the parent project.
