Narrative
NDS68 is a new maize synthetic variety created by NDSU maize breeding program as a source of short-season Stiff Stalk (SS) inbred lines. This population was developed by adapting Iowa Stiff Stalk Synthetic (BSSS) to northern U.S. environments and improving it through three cycles of stratified mass selection under short-season environments. Sample sizes of 30,000 plants were used, in grid isolations, to select the earliest 400 individuals within each selection cycle. Lodging and disease resistance were secondary traits added to the selection. As expected,selection response was successful as conducted with several other populations with this cost/efficient methodology on a highly heritable trait, easy to screen , and barely influenced by the environment. This population is a new source of short-season high yielding female inbred lines for northern U.S. environments. The total cost of this selection program including flowering time to develop this new population was under $1,000 across years. Isolations were effective to move this corn north.
