Quantitative Gene Action And Interrelationships Of Protein Content With Some Metrical Traits Of Oats, Harbans Singh Sraon
Quantitative Gene Action And Interrelationships Of Protein Content With Some Metrical Traits Of Oats, Harbans Singh Sraon
Electronic Theses and Dissertations
The objectives of this study were (a) to determine gene action, heritability and number of effective factors controlling protein content in oats, (b) to investigate the interrelationships of protein content with other agronomic characters, and (c) to evaluate the feasibility of utilizing A. sterilis germplasm in oat breeding projects. Four genetically distinct cultivars with protein content ranging from 15.7 to 26.6 percent were crossed in all possible combinations to make a complete set of diallel crosses. The data suggested additive gene action and partial dominance for protein content. Groat percentage and number of panicles showed overall partial dominance. Yield and …

Improving Water Use Efficiency Of Smooth Bromegrass By Selecting For Regrowth, Delmer F. Gross
Electronic Theses and Dissertations
Sixty-nine genotypes, including 60 from the variety Saratoga smooth bromegrass, three from South Dakota 7 smooth bromegrass, and two each of reed canarygrass, orchardgrass, and creeping meadow foxtail as check species were selected for regrowth from a source nursery containing over 37,000 genotypes. In addition, four genotypes of Saratoga with poor regrowth capability were selected as checks. These 73 genotypes were placed in a greenhouse environment to evaluate digestibility (IVDMD), and other characteristics. After three harvests, 34 genotypes were vegetatively propagated in a field experiment to determine regrowth capabilities. NCE rates were not correlated highly with yield in the greenhouse …
