Characterization of a diverse USDA collection of wild soybean (glycine soja siebold & zucc.) accessions and subsequent mapping for seed composition and agronomic traits in a RIL population
(University of Missouri--Columbia, 2018)
The relatively low genomic variation of current U.S. soybean [Glycine max (L.) Merill] cultivars constrains the improvement of grain yield, seed quality, and other agronomic traits within soybean breeding programs. Recently, ...

There are many traits that influence crop adaption to a new environment so that it can perform as a farmer would prefer. In these chapters, I have shown the influence of the genetic mechanisms behind pod shatter, days to ...
Cotton and maize primary root growth responses to water deficit : comparative physiological and metabolic analysis
(University of Missouri--Columbia, 2019)
