DESCRIPTION:Wheat (Triticum aestivum L.) is a widely consumed staple crop a
 nd essential component of a healthy whole-grain diet. One component of whe
 at\, fructans\, is known to serve physiological roles in the plant and con
 fer health benefits to humans. Fructans serve as reserve carbohydrates and
  osmotic regulators against stresses (i.e.\, drought\, cold temperatures\,
  and salinity) that affect grain yield in the wheat plant. For humans\, fr
 uctans are prebiotics that promote growth of healthy gut bacteria\, aid in
  immune support\, reduce colon cancer incidence\, and support bone health.
  Given the roles of fructans in plant and human physiology\, breeding for 
 wheat grain fructan content would produce climate resilient\, nutritionall
 y improved varieties.\n\nTo determine the feasibility of breeding for whea
 t grain fructan content\, a multi-environment trial was designed to examin
 e the impacts of genotype-by-environment interactions on grain fructan con
 tent. Based on the results of the trial\, genomic selection (GS) was imple
 mented with two selection methodologies in a population of winter wheat. T
 otal realized gain in wheat grain fructan content was significant over two
  cycles of selection with no significant difference observed in gains betw
 een selection methodologies. The use of an optimum contribution selection 
 (OCS) methodology did not adequately control inbreeding relative to trunca
 tion selection\; however\, genetic variation was better conserved in OCS p
 opulations. While further research is needed to develop methods to adequat
 ely control inbreeding in populations developed with GS\, the results of t
 his research support the hypothesis that GS can be utilized for breeding n
 utritionally improved\, climate resilient varieties.
