Quantitative trait locus mapping of yield and yield components in barley (Hordeum vulgare L.)

Creator:: Traore, Abdoulaye
Abstract:: Higher grain yield is a key objective in barley (Hordeum vulgare. L) breeding. Despite extensive research on the genetics of yield and its components, selection for yield per se is still the most extensively employed because of negative relationships among components, modest correlations between yield and any particular component, and...

Estimates of genetic variance and heterosis in F₁ winter x spring barley crosses (Hordeum vulgare, L.)

Creator:: Harrabi, Moncef Mohamed
Abstract:: Four winter and four spring barley cultivars along with their F₁ hybrids were grown on the Hyslop Agronomy Farm near Corvallis, Oregon, a high rainfall site (over 1000 mm annually) located in the Willamette Valley. The experiment consisted of four replications. Ten seeds of each F₁ and parents were seeded...

Nitrate nitrogen accumulation and distribution in the soil profile during a fallow grain rotation as influenced by different levels of soil profile moisture

Creator:: Aktan, Selman
Abstract:: The effect of different soil moisture levels on the amount and location of NO₃ -N accumulation in the soil profile were studied. The cultivars used in this study were Mcdermid, a soft white winter wheat, and Hudson, a medium early winter barley. Moisture treatments simulating dry, normal and wet fallow...

Some components of test weight of soft white wheat

Creator:: Shenk, Myron Daniel
Abstract:: Studies of some components of test weight in Soft White wheat revealed distinct subclass differences. Wheat kernels of Soft White more completely occupied a given volume than did kernels of White Club. The Soft White kernels were larger and had a higher density than the White Club kernels. Because of...

Effects of three herbicides on yields of five cultivars of winter wheat (Triticum aestivum L. em Thell)

Creator:: Yahyaoui, Amor
Abstract:: With the development of new selective herbicides and the frequent change in commercial wheat cultivars, information is needed as to the possible interaction between cultivars and herbicides. The responses of five genotypically diverse wheat cultivars (Bezostaya, Daws, Maris Hobbit, Stephens and Yamhill) to diuron [3-(3,4-dichloropheny1)-1,1- dimethylurea], diclofop methyl 2-[4-(2,4-dichlorophenoxy)phenoxy] propanoate...

Genetic studies with Russian wheat aphid (Diuraphis noxia Mordvilko) in PI 294994 bread wheat (Triticum aestivum L.)

Creator:: Elsiddig, Ahmed A.
Abstract:: Russian wheat aphid (RWA), Diuraphis noxia (Mordvilko), is a widely distributed species in western north America, and a major economic pest of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.). The objectives of this study were to : 1) determine the inheritance of seedling and adult plant resistances in...
