Monitoring and Evaluating the Susceptibility of Colorado Potato Beetle, Leptinotarsa decemlineata Say, against Insecticides in the Columbia Basin of Northeastern Oregon

Creator:: Yang, Pahoua
Abstract:: Potato (Solanum tuberosum L.) is among one of the largest and most important staple food crops in the world. One of the most productive growing potato regions is the USA is the Oregon and Washington Columbia Basin. Both states produce approximately 26% of the USA potatoes in the market. In...

Analyzing the Incorporation of Cover Crops on a Tropical Island: Puerto Rico

Creator:: Torres Remigio, Angel
Abstract:: Puerto Rico’s climate varies greatly even if it is categorized as a tropical climate. On some parts of the island, there are desert like conditions where rainfall averages 36 inches a year unlike the western side or the central part of the island where rainfall averages 200 inches.1 Heavy rains...

Nature of the inheritance of gluten strength and carotenoid pigment content in winter by spring and durum wheat crosses (Triticum turgidum L. Var. durum)

Creator:: Ammar, Karim
Abstract:: Durum wheat cultivars for North-Eastern Oregon have to be competitive in terms of their yield potential with soft white winter wheat cultivars and meet strict quality requirements of the milling industry. Combining the high yield potential of fall planted durum wheat cultivars which have an acceptable level of winter hardiness...

Water relations in red and white clover seed crops

Creator:: Oliva, Ruben N.
Abstract:: Both red (Trifolium pratense L.) and white (Trifolium repens L.) clover seed yields can be highly variable and low in western Oregon. The objectives of this study were to: i) determine crop water requirements and supplemental irrigation timing, and ii) quantify the effects of soil and water status on inflorescence...

Genetics of partial incompatibility and improvement of haploid production in Hordeum vulgare L. x H. bulbosum L. crosses

Creator:: Chen, Fu-chiang and Chen, Fuqiang
Abstract:: The production of barley (Hordeum vulgare L.) haploids by crossing with H. bulbosum is a widely used tool in breeding and genetics. Certain barley genotypes have low seed set in this interspecific cross, a phenomenon known as partial incompatibility. Haploid production efficiency and gamete sampling are important issues with the...

Duration and rate of grain filling and subsequent grain protein content in selected winter wheat populations

Creator:: Mou, Beiquan
Abstract:: The lack of information regarding the inheritance of the duration and rate of grain filling, and the possible relationship between grain fill and grain protein content in wheat prompted this study. Early maturing Chinese cultivars, 'AI Feng 2' and 'CB 83-52', and late maturing cultivars adapted to Oregon, 'Stephens' and...

Fallow water retention and wheat growth as affected by tillage method and surface soil compaction

Creator:: Schillinger, William F.
Abstract:: No-tillage winter wheat (Triticum aestivum L.) grown in a wheat-fallow cropping system has consistently produced lower grain yields than conventionally tilled soils in the semiarid Pacific Northwest. A 2-year study was conducted in a long-term tillage trial at Moro, OR to determine factors responsible for differences in wheat growth and...

Establishment of Kura clover for seed with wheat intercrops

Creator:: Snelling, John P.
Abstract:: Kura clover (Trifolium ambiguum M. Bieb.) is slow to establish and has low seed yields the year after establishment. Intercropping a cereal grain during clover seed field establishment could provide additional revenue to seed growers, provided that intercropping did not jeopardize future clover seed yields. Factorial combinations of spring- and...
