Abstract This field test was conducted in conventionally planted and tilled soybeans at the E. V. Smith Plant Breeding Unit of Auburn University at Tallassee, AL. Eleven treatments including an untreated control were replicated 4 times in a RCBD. Each plot was 6 rows wide (30 inch row spacing) and 40 ft long. Replicates were separated by a 15 ft alley. Treatments were applied in water on 13 Aug using a boom sprayer with one 80003 flat fan nozzle per row operating at 32 psi and delivering 8.0 gal/acre. Insect populations were monitored with 2 beat sheet samples per plot. One beat sheet sample was done when 36 inches of the 2 adjacent rows were sampled by beating the plants vigorously over the beat sheet. Insects were identified and recorded in situ. Samples were taken 18 h before treatment and at 3, 7 and 10 DAT.

The identification and the characterization of genetic diversity of rice was the first step in the rice plant breeding program. This study aimed to detect indica or japonica sub-species on upland rice Situ Bagendit and inbred rice Ciherang using molecular markers ORF 29-TrnC (GCA) on the chloroplast genome. Rice was included to the indica sub-species if the 32 bp insertion on ORF 29-TrnC (GCA) sequence was found, on the contrary, if the deletion 32 bp on ORF 29-TrnC (GCA) was found then it was included to the japonica sub-species. DNA isolation was examined from the leaves of the rice plants, and then it tested quantitatively to determine the transparency and DNA concentration from the isolation results. PCR amplification was performed using a pair of primers CP2 and it was followed by agarose gel electrophoresis. The visualization of the DNA bands used the gel documentation. Sequencing of PCR products produced a long base 390 bp in Situ Bagendit rice and 390 bp in Ciherang rice. Analysis of the sequences showed that the insertions occurred throughout the 32 bp in Situ Bagendit rice and the insertions occurred throughout the 32 bp in Ciherang rice. The results showed that upland rice Situ Bagendit and inbred rice Ciherang were included in the indica sub-species. The knowledge of variety of genetics of rice can be used as bio-information in the plant breeding program. Further, the knowledge can be used to protect in genetic power source, the selection and the composing of superior varieties of rice which is tolerant with kinds of biotic and abiotic factor.

Summary In–situ upgrading (IU) is a promising method of improved viscous– and heavy–oil recovery. The IU process implies a reservoir heating up and exposure to a temperature higher than 300°C for a time period long enough to promote a series of chemical reactions. The pyrolysis reactions produce lighter oleic and gaseous components, while a solid residue remains underground. In this work, we developed a numerical model of IU using laboratory experience (kinetics measurements and core experiments) and validated the results by applying our model to an IU field–scale test published in the literature. Finally, we studied different operational conditions in a search for energy–efficient configurations. In this work, two types of IU experimental data are used from two vertical–tube experiments with Canadian bitumen cores (0.15 and 0.69 m). A general IU numerical model for the different experimental setups has been developed and compared with experimental data, using a commercial reservoir–simulator framework. This model is capable of representing the phase distribution of pseudocomponents, the thermal decomposition reactions of bitumen fractions, and the generation of gases and residue (solid) under thermal cracking conditions. Simulation results for the cores exposed to a temperature of 380°C and production pressure of 15 bar have shown that oil production (per pseudocomponent) and oil–sample quality were well–predicted by the model. Some differences in gas production and total solid residue were observed with respect to laboratory measurements. Computer–assisted history matching was performed using an uncertainty–analysis tool with the most–important model parameters. To better understand IU field–scale test results, the Shell Viking pilot (Peace River) was modeled and analyzed with the proposed IU model. The appropriate gridblock size was determined and the calculation time was reduced using the adaptive mesh–refinement (AMR) technique. The quality of products, the recovery efficiency, and the energy expenses obtained with our model were in good agreement with the field test results. In addition, the conversion results (upgraded oil, gas, and solid residue) from the experiments were compared with those obtained in the field test. Additional analysis was performed to identify energy–efficient configurations and to understand the role of some key variables (e.g., heating period and rate and the production pressure) in the global IU upgrading performance. We discuss these results, which illustrate and quantify the interplay between energy efficiency and productivity indicators.

Southern and in situ hybridization were used to examine the chromosome constitution, genomic relationships, repetitive DNA sequences, and nuclear architecture in durum wheat × tritordeum hybrids (2n = 5x = 35), where tritordeum is the fertile amphiploid (2n = 6x = 42) between Hordeum chilense and durum wheat. Using in situ hybridization, H. chilense total genomic DNA hybridized strongly to the H. chilense chromosomes and weakly to the wheat chromosomes, which showed some strongly labelled bands. pHcKB6, a cloned repetitive sequence isolated from H. chilense, enabled the unequivocal identification of each H. chilense chromosome at metaphase. Analysis of chromosome disposition in prophase nuclei, using the same probes, showed that the chromosomes of H. chilense origin were in individual domains with only limited intermixing with chromosomes of wheat origin. Six major sites of 18S–26S rDNA genes were detected on the chromosomes of the hybrids. Hybridization to Southern transfers of restriction enzyme digests using genomic DNA showed some variants of tandem repeats, perhaps owing to methylation. Both techniques gave complementary information, extending that available from phenotypic, chromosome morphology, or isozyme analysis, and perhaps are useful for following chromosomes or chromosome segments during further crossing of the lines in plant breeding programs.Key words: In situ hybridization, molecular cytogenetics, plant breeding, Hordeum chilense, Southern hybridization, durum wheat, hybrids.

Abstract A field study was conducted at the Macon Ridge Branch, Northeast Research Station, located near Winnsboro (Franklin Parish), Louisiana, to evaluate the efficacy of several B. thuringiensis insecticides for soybean looper control. Test plots were 50 ft long by 5 rows with a 40 inch row spacing and were arranged in a randomized complete block design with four replications. Insecticides were applied with a tractor and compressed air sprayer calibrated to deliver 10 gpa at 38 psi through TX8 hollow cone nozzles (2 per row). Insecticide treatments were applied to soybeans in the R5 stage of growth (beginning seed) on 25 Aug. Posttreatment counts, consisting of 25 sweeps per plot, were taken with a 15 inch diameter muslin net at 2, 5, and 7 DAT. No rainfall occurred and the plots were not irrigated during the experimental period. Data were analyzed using analysis of variance followed by means separation according to DMRT.
