The objective of this research is to establish a HOLL plus soybean breeding and molecular selection program dedicated to developing high yielding maturity group III and IV soybean varieties for Missouri farmers.
The research project will involve dedicating resources to a soybean breeding strategy of combining the HOLL and other seed composition traits into high yielding genetic backgrounds targeted at maturity group III and IV for Missouri soybean farmers. In the first two years of the project, new populations will be developed with the best sources of all of the plus traits as parent material. An intricate crossing, advancement, and selection strategy will then follow to carry out the soybean breeding and variety development work. All of the plus traits have been characterized individually and have working perfect molecular markers available for selection. In order to capture all of the variant genes required for HOLL plus variety and germplasm development, a modified soybean breeding strategy will need to be utilized. Fortunately, an intensive and specialized back crossing program currently exists which is aimed at incorporating the HOLL trait into elite cooperator soybean varieties and breeding lines through a parallel trait introgression approach using molecular markers. The research would leverage the cooperator and USDA HOLL plant material in the current cooperator backcrossing program as a foundation, as well as other unique cooperator and USDA HOLL and HOLL plus breeding lines and populations currently being developed, for incorporating the proposed plus traits through a similar parallel back crossing program utilizing molecular markers associated with the various plus traits.
