The occurrence of seed-producing wheat x jointed goatgrass hybrids in infested wheat fields suggests the possibility of gene flow between the two species. This study investigates 'Madsen' wheat x jointed goatgrass F₁ and reciprocal backcross derivatives produced in experimental field plantings. Electrophoresis of the high molecular weight (HMW) glutenin seed...
Single nucleotide polymorphisms (SNPs) are the most common DNA polymorphisms in plant and animal genomes. SNPs were identified in the allele sequences of up to 12 sunflower (Helianthus annuus L.) genotypes for a genome-wide sample of 81 loci originally mapped using restriction fragment length polymorphism (RFLP) markers. The RFLP loci...
Domesticated forms of wheat exhibit traits that have increased their adaptation
to cultivation by humans. Some of the most critical adaptive differences involve
changes to morphological features that make the crop easier to harvest like ear rachis
stiffness (brittle to non-brittle rachis) and the ease with which the seed is...
The easy picking characteristic, expressed as low pod detachment force (PDF),
offers a way to decrease pod damage in bush green beans mechanically harvested for
processing and fresh market, and makes hand picking easier and faster. This study was
undertaken to examine inheritance in a cross of two green bean...
Nuclear DNA flow cytometry was used to differentiate ploidy level and determine nuclear DNA content in Rubus. Nuclei suspensions were prepared from leaf discs of young leaves following published protocols with modifications that included: increasing the stain concentration, adding the stain after the RN ase treatment instead of adding it...
It is often perceived that late maturity of grape gives a more complex aroma
profile to Pinot noir wine, however, there is little understanding of the basic flavor
chemistry of grape maturity on wine aroma. The aroma contributing compounds in
Pinot noir were first identified by aroma extract dilution analysis...
Sclerotinia sclerotiorum (Lib.) de Bary is a necrotrophic pathogen capable of causing white mold, a severe disease in common bean. White mold is of particular concern to the Oregon snap bean processing industry, where processors allow less than
3% incidence in harvested shipments. Breeding for white mold resistance in beans...
The European hazelnut (Corylus avellana L.) is a tree nut crop that is important in Oregon, which produces 99% of the United States’ hazelnuts but only 5% of the world’s supply. In order to maintain this market share, farmers in Oregon need cultivars that produce high quality nuts, mature early,...
