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...

Influence of population density on light interception and grain yield involving wheat hybrids

Creator:: Ganapathy, Mapangada Chengappa
Abstract:: Six wheat hybrids from two sets of parents and their respective parents were grown at Hyslop Agronomy Farm near Corvallis, Oregon in the year 1965-66. The object of the experiment was to evaluate the influence of population densities and different planting patterns on grain yield and factors which determine grain...

Ultrastructural study of the embryo during germination involving douglas fir (Pseudotsuga menseizii Franco) seeds

Creator:: Hsu, Kay Yong-Yong
Abstract:: The seeds of Douglas fir, a representative of the gymnosperm flora, were studied at six stages of germination to discern the structures of food reserves and to study ultrastructural changes occurring during germination in the embryo and resulting seedlings. The materials were fixed in three fixatives, dehydrated with ethanol series,...

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....

Evaluation of three methods of selection in relation to yield and yield stability in winter wheat (Triticum aestivum Vill., Host)

Creator:: Charoenwatana, Terd, 1937-
Abstract:: The effectiveness of early generation selection for yield and yield stability and the possible identification of superior parental combinations were studied in winter wheat populations representing different levels of genetic diversity. Experimental material for evaluating yield stability consisted of nine bulk and seven modified bulk populations derived from nine parental...

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...

Effect of seed protein content on plant growth of barley and wheat

Creator:: Lopez, Arturo
Abstract:: The purpose of this study was to evaluate the effect of seed protein content on plant growth of barley (Hordeum vulgare L. ) and wheat (Triticum aestivum L. ). The effects of nitrogen application on chemical and morphological characteristics of the seed were also studied. Seeds of 'Casbon' winter barley...

The physiology of seasonal growth in tall fescue varieties (Festuca arundinacea Schreb.)

Creator:: Blacklow, Warren Marcus
Abstract:: The winter and summer growth of varieties of tall fescue (Festuca arundinacea Schreb.) that had originated from the Mediterranean region (Oregon 1000 and Tunisia) and northern Europe (Alta) were studied outdoors in the Mediterranean climate of western Oregon, and in greenhouses and controlled environment chambers. Treatments of temperature, photoperiod and...

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...
