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

Download or read book Discovery Characterization and Utilization of Rpp Genes for Resistance Against Soybean Rust written by Silas Paul Childs and published by . 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.
