This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean rust (Phakopsora pachyrhizi H. Syd. & Syd.) causes significant economic losses in yield in many soybean-growing areas worldwide. Since most if not all commercial soybean cultivars are susceptible, research continues to search and characterize resistance. Perennial Glycine species have many useful traits including rust resistance that if transferred to soybean may provide many economic benefits. In this study, four F2 populations of G. tomentella derived from crossing a rust susceptible (PI 441011) with four rust resistant accessions (441008, 483218, 509501, and 583970) were evaluated for rust resistance. About 100 F2 individuals per population and parents were inoculated with P. pachyrhizi under controlled greenhouse conditions. Rust resistance was assessed on a qualitative scale based on lesion color and sporulation of uredinia. Segregation analysis of F2 populations indicated several genetic models explained the inheritance of resistance based on how the data were interpreted; the models included one dominant gene and two dominant genes. The rust resistance gene or genes in these four accessions of G. tomentella may represent unique resistance to P. pachyrhizi not found in soybean. Survival and production of urediniospores of P. pachyrhizi depends on its hosts, the environment, and exposure to fungicides. In this study, uredinia in infected leaves were washed, incubated at different temperatures and fungicide concentrations, and evaluated for re-sporulation and germination of urediniospores. There was a significant (P

This book was released on 2017 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean rust is a disease of soybean caused by Phakopsora pachyrhizi Syd. & P. Syd and Rpp genes can help protect soybean from this disease. In this study, a novel Rpp gene was mapped to a 154 kb interval on chromosome 19 in PI 605823 and named Rpp7. In addition, five germplasm accessions were identified which had unique reaction phenotypes to nine diverse P. pachyrhizi isolates and may carry novel Rpp alleles. Four new sources of resistance were mapped to either the Rpp3 or Rpp6 locus using bulked segregant analysis. Eleven accessions with a putatively novel Rpp3 allele were identified with a KASP4́Ø marker developed within an Rpp3 candidate gene region. In addition, 11 breeding lines with stacked Rpp1 and Rpp3 loci were selected with molecular markers, and the introgression sizes of Rpp loci were estimated in 13 breeding lines or NILs using the SoySNP50K iSelect Beadchips.

Available in PDF, EPUB and Kindle. Book excerpt: Pathogen resistance to fungicides has become a challenging problem in the managing of crop diseases and has threatened the performance of some highly potent commercial fungicides. Worldwide, resistance to more than one hundred different active ingredients has been reported. This book compiles information on fungicide resistance over the past three decades on the status, development, and processes involved in the build-up of resistance in pathogens to different groups of fungicides, while also suggesting various measures for managing this problem.

Book excerpt: The soybean is a crop of global importance and is one of most frequently cultivated crops worldwide. It is rich in oil and protein, used for human and animal consumption as well as for industrial purposes. Soybean plants also play an important role in crop diversification and benefit the growth of other crops, adding nitrogen to the soil during crop rotation. With contributions from eminent researchers from around the world, The Soybean provides a concise coverage of all aspects of this important crop, including genetics and physiology, varietal improvement, production and protection technology, utilization and nutritional value.
