Genotype-environment interaction in winter wheat F₁ progeny

Creator:: Peterson, C. J.
Abstract:: Seven winter wheats were evaluated for plant height, the components of yield and yield in a diallel cross at Pendleton, Oregon and Lind, Washington. An additional parent was added to the diallel cross at Pullman, Washington. Two levels of nitrogen and five replications were utilized at each of the locations....

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 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...

Regulation of ovine pituitary function with estrogen alone and in combination with progresterone

Creator:: Osland, Robert Birger
Abstract:: Five experiments were conducted to study the activity of the pituitary gland in sheep as influenced by estrogen administered alone or in combination with progesterone. Particular emphasis was given to the study of gonadotropic activity. Mature wethers (experiments I, III, IV and V) or ewes (experiment II) were utilized as...

Lower Deschutes River, Oregon: discharge and the fish environment

Creator:: Aney, Warren W., Montgomery, Monty L., and Lichens, Allan B.
Abstract:: The lower Deschutes River of northcentral Oregon has a historically uniform discharge record. Significant reductions in discharge below the seasonal norms will degrade the environment for migratory and resident salmonids by increasing siltation and gravel compaction, and by reducing intragravel water dissolved oxygen content. Fish spawning will be limited by...

Reproduction in the eastern cottontail rabbit in Oregon

Creator:: Trethewey, Donald Edwin
Abstract:: Reproductive characteristics of introduced eastern cottontail rabbits, Sylvilagus floridanus (J. A. Allen), were determined from 486 rabbits collected between January 1, 1968 and June 30, 1969, near Corvallis, Oregon. Sex ratios were 1:1 for all rabbits collected and for all embryos 20 days or more gestation. On the basis of...
