Inheritance of plant height, date of heading and tillering in three wheat crosses

Creator:: Nandpuri, Karam Singh
Resource Type:: Dissertation

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 (2-chloroethyl)-trimethylammonium chloride on the ribonucletic acid content of wheat (Triticum aestivum) leaves

Creator:: Baldwin, Richard William, 1933-
Abstract:: A study was made on the effect of CCC (2-chloroethyl)-trimethyl-ammonium chloride), a plant growth retardant, on the RNA (ribonucleic acid) content of wheat plants, It was found that the RNA content of wheat leaves generally decreased with increasing levels of CCC up to 1x10⁻⁵M. Thereafter, the RNA content again increased...
Resource Type:: Dissertation

Indole-3-acetic acid in (2-chloroethyl)-trimethylammonium chloride-treated club wheat (Triticum aestivum compactum)

Creator:: Gould, Walter Leonard
Abstract:: Studies were conducted to verify the existence of IAA in wheat seedlings and to determine the effect of (2-chloroethyl)-trimethyl-ammonium chloride (CCC) on the IAA content of club wheat, Triticum aestivum compactum, variety Omar. The shoots of CCC-treated and untreated wheat plants were extracted with ethanol, the plant extract purified, separated...
Resource Type:: Dissertation

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...

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...
Resource Type:: Dissertation

The influence of various climate and edaphic factors on the toxicity of 2-tert. butylamino-4-ethylamino-6-methylthio-s-triazine (Igran) to winter wheat (Triticum aestivum Vill., Host)

Creator:: Figuerola, Luis Fernan
Abstract:: Several studies were conducted to determine the influence of various environmental factors on the toxicity of 2-tert.butylamino- 4-ethylamino-6-methylthio-s-triazirxe (Igran) to winter wheat. The effect of temperature on Igran toxicity was studied by growing wheat plants in pots submerged in water baths to control soil temperature and in controlled-environment chambers. Igran...
Resource Type:: Dissertation

Evaluation of parental performance for grain yield in two populations of wheat (Triticum aestivum Vill., Host)

Creator:: Alcala de Stefano, Maximino
Abstract:: Six winter wheat cultivars were evaluated for their breeding value in transmitting superior genetic factors for grain yield to subsequent progeny. The cultivars were selected on the basis of their potential grain yield and divided into two populations. Population I was comprised of three cultivars which have been in commercial...
Resource Type:: Dissertation

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...
Resource Type:: Dissertation

Adaptability of winter wheat cultivars to dryland conditions and their response to water stress

Creator:: Keim, Don Lee
Abstract:: Winter wheat cultivars (Triticum aestivum) were evaluated for their response to water stress and adaptability to a wide range of moisture limited environments. Grain yield was analyzed for ten cultivars at six locations across four years. Regression of the cultivar mean on the year-location mean was used as a measure...
