Heritabilities and associations of seed yield components and seed yield in tall fescue (Festuca arundinacea, Schreb.)

Creator:: Thomas, Johnny Ray
Abstract:: Estimates of heritability and associations of tiller number, seed number, seed weight, and seed yield were determined in two groups of tall fescue. Group E was early maturing and had eight parental clones, while group I was intermediate in maturity and had nine parental clones. The parents and five progeny...

Combining ability and gene action estimates and the association of the components of yield in winter wheat crosses

Creator:: Kronstad, Warren E. (Warren Ervind), 1932-
Abstract:: A diallel cross consisting of ten parents was grown on the Hyslop Agronomy Farm near Corvallis, Oregon, in order to obtain estimates of the gene action contributing to yield and its components in wheat. Gene action estimates were obtained by two methods of diallel analysis and from narrow sense heritability...

The influence of plant densities on gene action estimates and associations in seven winter wheat parents and their F₂ progeny

Creator:: Saini, Surinder Kumar
Abstract:: The F₂ progeny from a diallel cross involving seven winter wheat parents along with the parents were grown at the Hyslop Agronomy Farm near Corvallis, Oregon to determine the influence of three plant densities on gene action estimates for yield and its primary components. The plant densities were designed to...

The distribution, growth habits, and control of German velvetgrass (Holcus mollis L.) in Western Oregon

Creator:: Lee, William O., 1911-
Abstract:: A study was conducted on German velvetgrass (Holcus mollis L.), a weedy, rhizomateous perennial grass introduced in the United States in relatively recent years, The purpose of this study was to learn more about its distribution, growth habits, and control under conditions found in Western Oregon. German velvetgrass infestations of...

Relationship of nitrogen level to medusahead, Taeniatherum asperum (Sim.), competition with wheatgrass and silica content

Creator:: Brown, Dean Allen
Abstract:: Studies were conducted to determine the competitive ability of medusahead, Taeniatherum asperum (Sim.), for nitrogen when grown in association with perennial range grass species. The method used to determine this competitive ability was to compare the dry weight, percent nitrogen, and total nitrogen of medusahead and perennial wheatgrass species growing...

The effect of source and size of parent tuber on yield of the Russet Burbank and Kennebec potato

Creator:: Youngberg, Harold Wayne, 1929-
Abstract:: Samples of Russet Burbank and Kennebec seed potatoes used by Oregon growers were grown in replicated plots at Klamath Falls, Prineville and Corvallis. Observations were made of total yield, yield of U.S. No. 1 tubers and number of stems produced per plot. Total yields of the Russet Burbank variety were...

Exogenous and endogenous factors related to seed germination and vigor in certain varieties of sugarbeet Beta vulgaris L.

Creator:: Kim, Syng Chul
Abstract:: Studies were conducted on the causes of low germination of monogerm sugarbeet seed grown in western Oregon. Emphasis was placed on the identification and measurement of endogenous inhibitors as related to the germination and vigor. Both qualitative and quantitative analytical methods were applied to examine the organic substances in the...

Confidence limits for fluoresence tests of ryegrass (Lolium sp.)

Creator:: Copeland, L. O. (Lawrence O.), 1936-
Abstract:: Studies were conducted to determine the variability existing in repeated fluorescence tests of annual and perennial ryegrass (Lolium multiflorum and L. perenne, respectively). Sources of variation considered were within-sample error, among-sample error, among-germinator error, and among-laboratory error. These were studied independently and the variation in each was compared to the...
