Developing a hemp dihaploid protocol

Creator:: Murphy, Sean K.
Abstract:: Cannabis production has gained popularity over the last 10 years. There is a growing demand for true-to-type grain, fiber, and resin crops. Breeding for homozygous trait development with traditional methods can take as long as 8 years. With dihaploid breeding, homozygosity can be achieved in 2 generations saving breeders time...

Assessing Petal-cutting bees (Megachile sp.) usage of Clarkia amoena (Onagraceae) petals through the lens of iNaturalist and a Garden Experiment

Creator:: Mead, Mallory
Abstract:: Farewell-to-spring (Clarkia amoena) is native to the Pacific Northwest and commonly found in gardens, due to its aesthetic value and purported benefits to pollinators. Oregon and Washington are home to five subspecies of C. amoena, yet commercially available seed is limited to C. amoena ssp. lindleyi and C. amoena cultivars....

Evaluation of fruit size and seed number in triploid and tetraploid Malus spp.

Creator:: Dempster, Jonathan and Contreras, Ryan N.
Abstract:: Fruit diameter of triploid and tetraploid Malus spp. accessions were evaluated based on ploidy and seed number. Pome size in relation to seed number and ploidy level was evaluated using Tukeys HSD in R. With 95% confidence, pome diameter was not impacted by seed number in these selections (Tukey’s HSD...

Mass Spectrometry-based Detection of Neonicotinoids on Honey Bees

Creator:: Trevor, Shear, Morré, Jeff, and Hooven, Louisa
Abstract:: With increasing use of new pesticide formulations worldwide to repel and kill unwanted organisms, negative consequences on non-target species such as honey bees and other pollinators are of increasing concern and not well studied. This study compares the nanotechnology based pesticide (NBP) Safari and its base neonicotinoid, dinotefuran, and their...

Identifying breeder-friendly INDELs that co-seggregate with SNPs associated with QTL for resistance to Fusarium solani root rot in snap bean (Phaselous vulgaris)

Creator:: Schmidt, Joseph A.
Abstract:: Fusarium solani is a chronic disease that causes root rot which affects bean production worldwide. Recently, a QTL map was generated which identified several SNPs which were found to be associated with resistance to the pathogen. To be useful in a breeding program, INDELs must be identified which co-seggregate with...

Germination of Pollen

Creator:: Gibson, Vane G. (Vane Garfield)
Abstract:: The object of this work was to determine, as far as possible, the germinating ability of pollen of different varieties of fruit. The work was started with the idea of making these determinations for both apples and pears but owing to lack of time and probably because the proper culture...

Orchard Cover Crops

Creator:: McCully, Russell Alfred and Hall, Frank E. (Frank Edward)
Abstract:: To the North West horticulturist there is no problem which confronts him of so great moment as that of soil fertility; and. no phase of horticulture is more deserving of the attention of fruit growers, than is given at the present time to the growing of orchard. cover crops.

Orchard Irrigation

Creator:: Schrack, Claud and Currin, Harvey William
Abstract:: Irrigation should be recognized as agricultural art of very wide applicability and value. Its association with the idea of desert reclamation has blinded the public mind to its value in reginos where there is no need of reclamation. It is a means of soil improvement to be employed, like other...
