Drainage water management practices affect water quality, soil properties, and crop production
(University of Missouri--Columbia, 2023)
. This dissertation includes results from four studies conducted at the MU Greenley Research Center, Grace Greeley farm, and Ross Jones farm. Long-term, no-till research evaluated the influence of a wheat (Triticum aestivum L.), radish (Raphanus raphanistrum subsp...
Characterization of diverse soybean genotypes for phosphorus uptake and use efficiency
(University of Missouri--Columbia, 2021)
was aimed at identifying and characterizing soybean genotypes which contrast in their ability to take up P and in their PUE. Results from pot and field experiments with diverse soybean genotypes, including SoyNAM parents, obsolete cultivars, commercial...
Genetic mapping of soybean cyst nematode resistance and evaluation of resistant germplasm in soybean and pennycress
(University of Missouri--Columbia, 2022)
architecture of SCN resistance in PI 90763, we mapped SCN resistance quantitative trait loci (QTL) through linkage and biparental mapping analyses. QTL on chromosomes 11 and 18, corresponding to the rhg1-a and rhg2 loci, respectively, were determined to govern...
