Cuphea laminuligera Koehne and Cuphea lutea Rose in Koehne are
undomesticated species having potential as oilseed crops. Genetic
markers and mating systems have not been described for these
species. Our objectives were to survey these species for allozyme
variation, analyze the segregation and linkage of polymorphic loci,
estimate autofertility and...
Cuphea is an herbaceous genus having species whose seed
storage lipids are predominantly medium-chain triglycerides (MCTs).
Cuphea lanceolate Ait, and Cuphea viscosissima Jacq. are central to
the breeding of Cuphea as a new commercial source of MCTs. The
objectives of this thesis were to develop a reliable method to
extract...
Making quality and winterhardiness in barley are "ultimate" phenotypes composed of
component, quantitatively inherited traits. A 69-point genome map of the seven chromosomes of
barley was used, in conjunction with multi-environment phenotypes for grain yield and malting
quality, to determine the chromosome locations of quantitative trait loci (QTLs). A combined...
Fiber flax (Linum usitatissimum L.) production in the Willamette Valley ended in
Oregon around 1957 before newly developed technology and fiber cultivars were
available. The purpose of this research was to explore the use of modern methods and
new cultivars.
Field studies were conducted to evaluate cultivars and optimum cultural...
Molecular DNA markers have become widely used in all areas of genetic
research. The objectives of this thesis were to develop polymorphic markers in sunflower
and utilize the markers for genetic and candidate gene analyses. Amplified fragment
length polymorphism (AFLP) markers were used to estimate genetic similarities and
assess the...
