Adaptability of winter wheat cultivars to dryland conditions and their response to water stress

Creator:

Keim, Don Lee

Abstract:

Winter wheat cultivars (Triticum aestivum) were evaluated for their response to water stress and adaptability to a wide range of moisture limited environments. Grain yield was analyzed for ten cultivars at six locations across four years. Regression of the cultivar mean on the year-location mean was used as a measure...

AN ABSTRACT OF THE THESIS OF DON LEE KEIM for the DOCTOR OF
Compensating effects and gene action estimates for the components of grain yield in winter wheat (Triticum aestivum, L. em Thell)

Creator:

Abi-Antoun, Michel

Abstract:

Five winter wheat cultivars and their diallel crosses were evaluated for plant height, harvest index, deading-maturity duration, the components of yield, (spikes per plant, spikelets per spike, kernel weight and kernels per spikelet)and total plant yield. Two diverse locations, Moro, a dryland site (250 mm annually) located in central Oregon...

Influence of aluminum toxicity in intergeneric crosses of wheat and rye

Creator:

Lopez-Benitez, Alfonso

Abstract:

A technique previously designed to screen wheat cultivars and segregating populations for tolerance to Aluminum utilizing nutrient solutions in growth chambers was found to be efficient in differentiating among cultivars of wheat, rye, and triticale for tolerance to Al under greenhouse conditions. A 5°C increase in temperature, from 25°C to...
