Results Of The Seventh International Winter Wheat Performance Nursery Grown In 1975, K. D. Wilhelmi, S. L. Kuhr, V. A. Johnson, P. J. Mattern, J. W. Schmidt

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This is the seventh report of results from an International Winter Wheat Performance Nursery (IWWPN) organized in 1968 by the Nebraska Agricultural Experiment Station and the Agricultural Research Service, U.S. Department of Agriculture, under a contract with the Agency for International Development, U.S. Department of State. The Nursery was designed to (1) test the adaptation of winter wheat cultivars in a range of latitudes, daylengths, fertility conditions, water management regimes, and disease complexes; (2) identify superior winter cultivars to serve as recipient genotypes for high protein and high lysine genes, and (3) test the degree of expression and stability of …

In Vitro Morphogenesis And Mutation Of Glycine Max L., Thomas Daniel Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soybean (Glycine max L. c.v. Consoy) tissue cultures were grown in synthetic media containing various concentrations and combinations of minerals, auxins, cytokinins, pH levels, and inorganic growth factors in a systematic procedure to establish optimum media for initiation and maintenance of callus. Further modification of the hormone level was employed to initiate callus morphogenesis. Normally toxic levels of atrazine were established in soybean calli media, and ethyl methanesulfonate (EMS) and X ray-induced mutant calli were selected for atrazine tolerance.

Optimal media for initiation and maintenance of soybean calli were developed and a defined medium was determined that consistently yields …

Alfalfa Latent Virus, A Naturally Occurring Carlavirus In Alfalfa, Yenkateswarlu Veerisetty, Myron K. Brakke

Department of Plant Pathology: Faculty Publications

Alfalfa latent virus (ALV), a new member of the carlavirus group, was isolated From alfalfa (Medicago sarivo) clones from rbe University of Nebraska experimental plots and from the Farmers' fields. The pea aphid, Acvrihosiphon pisum, transmitted this virus to M. sativa, Pisum sativum, and Viria faba. but not to Trifolium pratense. It was also sap transmissible to V. faba, V. villoso, and P. sarivum, but was not seed-borne in P. sariuum. In V. Jaba sap ALV was infectious at 65 but not at 70 C in 10 min. or …

Sedimentation Coefficients Of The Virions Of Soil-Borne Wheat Mosaic Virus, Myron K. Brakke

Department of Plant Pathology: Faculty Publications

The sedimentation coefficient of virion I of soil-borne wheat mosaic virus was estimated to be 219S, the same, within error, as the sedimentation coefficient of the dimer of virion II, estimated to be 218S. The monomer of virion II sedimented at 177S, and was 138 nm long. Another strain of the virus had a virion II (designated lIb) that was 92 nm long and sedimented at 159S. The two virus strains coexist in some fields.

Cotton Fireweed : Potential Poison : Research Roundup, J Dickson, R. Hill

Journal of the Department of Agriculture, Western Australia, Series 4

Although long known as a potential toxic species because of its content, and although it is widely distribuited in all Australian States, cotton fireweed has not generally been consdidered toxic because it is unpalatable and not usually eaten by stock.

In 1973 cattle deaths occured near Ravensthorpe which led to research into Senecio quadridentatus (cotton fireweed).

The plant must be seen as a potential toxic species in situations where the lack of other feed forces cattle to eat the normally unpalatable cotton fireweed.

Septoria Diseases Of Wheat, A. G. P. Brown

Experimental Summaries - Plant Research

The Effect of Septoria nodorum on Yield of 125 Wheat Cultivars. The aim of this experiment was as described for that of 1976. There were some modifications to the treatments which were as follows: (a) Most of the cultivars were 'new' and (b) Three levels of Septoria attack were set up:- 1. Low: cover sprayed throughout the season with the fungicide Difolatan. 2. Moderate: inoculated with Septoria three times, followed at heading out by cover spraying with Difolatan. 3. Severe: inoculated four times no fungicide. The 125 entries were sown as hill plots with the three Septoria environments as main …
