Effect of row spacings, seeding rates and nitrogen fertilizer rates on the agronomic performance of Yamhill and Hysolop wheat (Triticum aestivum L.)

Creator:: Chemli, Mohamed
Abstract:: The response of two newly released cultivars of winter wheat when grown under different row spacings, seeding rates and nitrogen levels were investigated. Measurements made included grain yield, tiller number per unit area, plant height, 300 kernel weight, bushel weight and protein content of the grain. Hyslop and Yamhill cultivars...

Estimates of heterosis for five agronomic traits in selected winter x spring and winter x winter wheat crosses (Triticum aestivum L. em Thell)

Creator:: Brajcich, P.
Abstract:: Concern regarding the lack of genetic variability and the apparent yield plateau reached in wheat breeding have prompted this investigation. The systematic crossing of spring and winter wheat types which have evolved to form somewhat different gene pools, may provide a source of additional usable genetic variability for future yield...

Influence of phosphorous and lime application on root growth and grain yield of two winter wheat cultivars (Triticum Aestivum, L em thell)

Creator:: Boulger, Mary Caroline
Abstract:: Differential grain yield response of two winter wheat cultivars ('Yamhill' and'McDermid) when grown on acid soils prompted this investigation. Root samples were taken at two soil depths at late tillering and anthesis from plots established on an acid nonpareil soil in Douglas County, Oregon. The soil pH was 5.2-5.3 and...

A study of methods of parental evaluation using testers to predict subsequent progeny performance in winter wheat (Triticum aestivum L.)

Creator:: Alexander, William Larry
Abstract:: The major objective of this study was to determine why certain winter wheat cultivars, when hybridized, will produce a greater proportion of desirable plants in subsequent, segregating generations. Three winter wheat parents were chosen as the experimental material, based on their known performance as parents. Yamhill and Pullman Selection 101...

Influence of different nitrogen and moisture levels on the expression of grain yield and protein content in selected wheat (Triticum aestivum, L. em Thell) and barley (Hordeum vulagre, L. em Lam.) cultivars

Creator:: Gomez-Pando, Luz
Abstract:: This investigation was conducted to provide information regarding 1) the relationship between the nitrogen percentage in the vegetative tissue of wheat and barley at various growth stages with grain protein and 2) to evaluate the possible association between grain yield and grain protein as influenced by different cultivars, nitrogen levels...

Competitive effect for grain yield of four cultivars in pure and mixed populations in wheat (Triticum aestivum Vill;, Host)

Creator:: Valencia-Villarreal, Jose Antonio
Abstract:: Concerns regarding maintaining wheat yield per hectare and extending the commercial life expectancy of cultivars grown in the Yaqui Valley of Mexico prompted this investigation. Four genetically diverse spring wheat cultivars were grown in pure stands and in all possible combinations at the Northwest Agricultural Research Center at Ciudad Obregon...

Evaluation of four quality factors in a selected winter x spring wheat cross (Triticum aestivum Vill., Host)

Creator:: Schumaker, Karen Sue
Abstract:: The nature of the genetic variation associated with a cross involving winter and spring wheat parents for four quality factors was evaluated. Yamhill, a soft white winter wheat, and Inia 66, a hard red spring wheat, were selected as parents for this study. They represented distinctly different phenotypes for the...
