The evaluation of heterosis for grain yield, total leaf area and malting quality in 21 spring barley crosses

Creator:

Carleton, A. E. (Albert Eugene), 1940-

Abstract:

The purpose of this study was to determine the amount of heterosis in three complex traits in barley and to investigate the concept of component interaction as a means of producing heterosis. The complex traits were grain yield, total leaf area, and malting quality. Seven varieties of spring barley were...

The effect of seeding rate on yield and yield components of two winter wheat varieties

Creator:

Rana, Prakriti Shumshere Jung Bahadur

Abstract:

Wheat is an important cereal crop in the Willamette Valley of Oregon and the stiff-strawed, high-yielding varieties are the predominant types grown. Observation of the effect of seeding rates on the yield and yield components are useful in determining which of the components contributes most to the yield of a...

The effect of heterozygosity on phenotypic stability in spring barley

Creator:

Smith, Garry Austin

Abstract:

The effect of heterozygosity on the phenotypic stabilities of six morphological plant characteristics was studied in hybrid crosses of two self-pollinated barley species Hordeum vulgare L., emend Lam. and Hordeum distichum L., emend Lam. Experimental material consisting of parents and their F₁ diallel progeny were grown at two field locations...
