Production Techniques For Crimson Seedless Table Grapes In Western Australia, Ian Cameron

Viticulture published reports

Crimson Seedless is a late season, red seedless table grape developed by D. Ramming and R. Tarailo in Fresno California for the United States Department of Agriculture. It was bred in 1979 when a white, late ripening seedless hybrid variety was crossed with Red Emperor (see Figure 1). The seedling, which became Crimson Seedless, was selected in 1983 but not released to industry in California until 1989.

Production techniques for Crimson Seedless were largely unknown when the variety was released to industry in Western Australia in 1996. Specific management techniques suitable for Californian conditions had been described by various authors. …

Mapping The Fas Locus Controlling Stearic Acid Content In Soybean, M. M. Spencer, V. R. Pantalone, E. J. Meyer, D. Landau-Ellis, D. L. Hyten Jr.

Department of Agronomy and Horticulture: Faculty Publications

Increasing the stearic acid content to improve soybean [Glycine max (L) Merr] oil quality is a desirable breeding objective for food-processing applications. Although a saturated fatty acid, stearic acid has been shown to reduce total levels of blood cholesterol and offers the potential for the production of solid fat products (such as margarine) without hydrogenation. This would result in the reduction of the level of trans fat in food products and alleviate some current health concerns. A segregating F₂ population was developed from the cross between Dare, a normal stearic acid content cultivar, and FAM94-41, a high stearic …

Department of Agronomy and Horticulture: Faculty Publications

Single-nucleotide polymorphisms (SNPs) provide an abundant source of DNA polymorphisms in a number of eukaryotic species. Information on the frequency, nature, and distribution of SNPs in plant genomes is limited. Thus, our objectives were (1) to determine SNP frequency in coding and noncoding soybean (Glycine max L. Merr.) DNA sequence amplified from genomic DNA using PCR primers designed to complete genes, cDNAs, and random genomic sequence; (2) to characterize haplotype variation in these sequences; and (3) to provide initial estimates of linkage disequilibrium (LD) in soybean. Approximately 28.7 kbp of coding sequence, 37.9 kbp of noncoding perigenic DNA, and …

‘Forrest’ Resistance To The Soybean Cyst Nematode Is Bigenic: Saturation Mapping Of The Rhg1 And Rhg4 Loci, K. Meksem, P. Pantazopoulos, V. N. Njiti, D. L. Hyten, P. R. Arelli, D. A. Lightfoot

Department of Agronomy and Horticulture: Faculty Publications

Field resistance to cyst nematode (SCN) race 3 (Heterodera glycines I.) in soybean [Glycine max (L.) Merr.] cv ‘Forrest’ is conditioned by two QTLs: the underlying genes are presumed to include Rhg1 on linkage group G and Rhg4 on linkage group A2. A population of recombinant inbred lines (RILs) and two populations of near-isogenic lines (NILs) derived from a cross of Forrest × Essex were used to map the loci affecting resistance to SCN. Bulked segregant analysis, with 512 AFLP primer combinations and microsatellite markers, produced a high-density genetic map for the intervals carrying Rhg …

High-Throughput Genotyping For A Polymorphism Linked To Soybean Cyst Nematode Resistance Gene Rhg4 By Using TaqmanTm Probes, Khalid Meksem, Eliza Ruben, David L. Hyten, Michael E. Schmidt, David A. Lightfoot

Department of Agronomy and Horticulture: Faculty Publications

An individual soybean breeder can generate over one hundred thousand new genotypes each year. The efficiency of selection in these populations could be improved if these genotypes were effectively screened with one DNA marker that identified an important gene, and if laboratory throughput was high and costs were low. Our aim was to develop a rapid genotyping procedure for resistance to the soybean cyst nematode. A high-throughput genotyping method was developed with fluorogenic probes to distinguish between two insertion polymorphisms in alleles of an AFLP marker that is located about 50 kbp from the Rhg4 gene candidate. The assay uses …

Conversion Of Aflp Bands Into High-Throughput Dna Markers, K. Meksem, E. Ruben, D. L. Hyten, K. Triwitayakorn, D. A. Lightfoot

Department of Agronomy and Horticulture: Faculty Publications

The conversion of AFLP bands into polymorphic sequence-tagged-site (STS) markers is necessary for high-throughput genotype scoring. Technical hurdles that must be overcome arise from genome complexity (particularly sequence duplication), from the low-molecular- weight nature of the AFLP bands and from the location of the polymorphism within the AFLP band. We generated six STS markers from ten AFLP bands (four AFLPs were from co-dominant pairs of bands) in soybean (Glycine max). The markers were all linked to one of two loci, rhg1 on linkage group G and Rhg4 on linkage group A2, that confer resistance to the soybean cyst nematode (Heterodera …

Two Large-Insert Soybean Genomic Libraries Constructed In A Binary Vector: Applications In Chromosome Walking And Genome Wide Physical Mapping, K. Meksem, K. Zobrist, E. Ruben, D. L. Hyten, T. Quanzhou, H-B. Zhang, D. A. Lightfoot

Department of Agronomy and Horticulture: Faculty Publications

Large DNA insert libraries in binary T-DNA vectors can assist in the isolation of the gene(s) under-lying a quantitative trait locus (QTL). Binary vectors facilitate the transfer of large-insert DNA fragments containing a QTL from E. coli to Agrobacterium sp. and then to plants. We constructed two soybean large-insert libraries from cv. Forrest in the pCLD04541 (V41) binary vector after partial digestion of genomic high-molecular-weight DNA with BamHI or HindIII. The libraries contain 76,800 clones with an average insert size of 125 kb, and therefore represent 9.5-fold haploid genome equivalents. Colony hybridization using a chloroplast-specific probe infers that …

Movement Of Crop Transgenes Into Wild Plants, Kathleen H. Keeler, Charles E. Turner, Margaret R. Bolick

School of Biological Sciences: Faculty Publications

Despite the great potential and increasing importance of other weed control options (Turner et al. 1992) and unwanted environmental side effects of some herbicides, herbicides constitute a very important means of weed control. The escape of herbicide resistance genes to wild, weedy plants could cause more severe weed problems, and presents a very real threat to the efficacy of herbicides as a weed control option. Therefore, management strategies that prevent, or reduce the likelihood and frequency of HRG escape through containment methods are advisable, as are mitigation plans in the event of HRG escape to wild plants.

Effects Of Tactical Responses And Risk Aversion On Farm Wheat Supply, Ross S. Kingwell

Natural Resources Research Articles

A discrete stochastic programming model of the farming system of the eastern wheatbelt of Western Australia is used to examine the effect of tactical responses and risk aversion on wheat supply. Including within-season tactical changes to wheat areas decreases the own-price elasticity of supply. By contrast, introducing risk aversion has no consistent effect on the own-price elasticity of supply. The implications for supply models are discussed.

Bulletin 4256 - Pecan Nut Cultivation, Aldo Labrosciano

Bulletins 4000 -

Pecans Carya illinoensis, an indigenous species to Northern America, are successfully grown between the latitudes of 25° and 35°. There is considerable variation in size and flavour of the 1000 or more varieties of the nuts.

Large scale production is concentrated in north America, Israel and South Africa. Plantings in Australia are in Victoria and New South Wales, and are developing slowly in Western Australia.

Pecans are well suited to Western Australian conditions where the soil is well drained. Though the trees are deciduous, they have no chill requirement and will flourish if water is not limiting.

Origin And Evolution Of Defective Interfering Rnas Of Tomato Bushy Stunt Virus, David A. Knorr, Thomas Jack Morris

School of Biological Sciences: Faculty Publications

Viruses with defective genomes have been identified in association with virtually every major family of viruses and have been widely utilized as tools for investigating virus functions in animal cell culture systems (Perrault, 1981). It is generally thought that defective interfering viruses (DIs) arise through deletion, rearrangement, or recombination of a competent viral genome. DIs tack the ability for independent existence relying on their parental helper viruses to supply factors required for replication, maturation, and/or encapsidation (Huang and Baltimore, 1977). The interference attributed to DIs is thought to result from competition with the helper virus for factors required in trans …

Eradicating Fruit Fly From Carnarvon, Kingsley Thomas Fisher

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

Late last year the Mediteranean fruit fly (Ceratitis capitata Weidemann) was eradicated from Canarvon, Western Australia by using an intergrated programme of sterile insect releases and bait spraying.

The eradication marked the end of a four-year study on the use and effectiveness of the Sterile Insect Technique, a biological control technique which uses an insect pest against itself. such a study can be used as a basis for treating other threatening insect pests, such as the serious cattle pest screw-worm fly, should they be found in Asustralia.

Being a biological control method, the Sterile Insect Technique is an exellent …
