Abstract

Molecular markers in perennial forages are becoming ubiquitous for marker assisted selection (MAS). Nevertheless, widespread implementation of MAS in perennial forage breeding programs for highly quantitative traits has not yet occurred. A primary reason is likely the cost associated with genotyping plants using molecular markers. Presented are cost-effective MAS strategies that are immediately implementable in most diploid or polyploidy perennial forage breeding programs. Breeding methods developed during the pre-MAS era maximize the ratio between additive variance and the square root of the phenotypic variance (i.e. hσA). With the advent of molecular markers, many new breeding methods based primarily on correlated selection responses between molecular markers and quantitative traits have been proposed (i.e. rσA). MAS strategies should be considered using molecular markers to improve hσA by enhancing traditional breeding methods. A selection strategy pyramid is envisioned with traditional maternal halfsib selection serving as the base followed by marker assisted paternity selection. With no additional cost within maternal and paternal maximum linkage disequilibrium based MAS strategies can be added. Finally, as the total cost to genotype one individual decreases, residual linkage disequilibrium based MAS strategies can be added to the above mentioned strategies or at some price point supplant these strategies.
