This book was released on 2007 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The P. coccineus collection of the U.S. Department of Agriculture National Plant Germplasm System (NPGS) Plant Introduction collection maintained at Pullman, WA, consisting of 478 accessions, but only 364 were available to be screened with the pathogen S. sclerotiorum to identify partial physiological resistance. 50.1 % of the accessions were identified to have high partial physiological resistance using the Petzoldt and Dickson (1996). Accessions were also characterized as to what species they were, based on hilum and seed coat appearance and emergence. Almost 30% of the accessions' seeds were either a mixture of species or labeled the wrong species.

This book was released on 2010 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sclerotinia sclerotiorum (Lib.) de Bary is a necrotrophic pathogen capable of causing white mold, a severe disease in common bean. White mold is of particular concern to the Oregon snap bean processing industry, where processors allow less than 3% incidence in harvested shipments. Breeding for white mold resistance in beans has been difficult due to quantitative inheritance and low heritability. We combined two quantitative trait loci (QTL) for physiological resistance to white mold: a QTL located on linkage group 7 from G122 and a B8 QTL from NY6020. The B7 QTL is linked to phaseolin for which a sequence characterized amplified region (SCAR) marker phaseolin has been used successfully to transfer the QTL in dry bean. The transfer in snap bean is more challenging because this QTL is also linked to the p locus which conditions the white-seeded trait. While most snap beans have T phaseolin seed protein, the OSU bush blue lake (BBL) materials have the S form of phaseolin, facilitating the use of T phaseolin as a selectable marker in breeding for white mold resistance. Thus, transfer of this QTL has to be coupled with breaking the linkage between colored seed and the resistance QTL. The B8 QTL is linked to the SS181650 SCAR and AW191200 random amplified polymorphic DNA (RAPD) markers. Oregon State University BBL bean germplasm originally developed with single QTL were crossed to pyramid the two resistance QTL. The assumptions made in combining these two sources of resistance are that the QTL are non-allelic and are additive. OSU 6229, OSU 6230, and OSU 6241 are advanced breeding lines that have the SS181650 allele from NY6020 and show statistically significant higher levels of resistance in the field and greenhouse (straw) test compared to susceptible cultivars. White-seeded, T phaseolin types were selected from a OR 91G x G122 BC2F3 population. The selected lines showed levels of resistance significantly better than the susceptible check cultivars in the straw test. The two sources were crossed and the progeny were subjected to three or more generations of phenotypic selection in the straw test. One hundred and forty eight families were planted in a randomized complete block design (RCBD). All families had been previously genotyped using the PHAS and SS181650 SCAR molecular markers. Plants were inoculated using actively growing mycelium of S. sclerotiorum and scored using a modified straw test to test for genetic additivity among marker classes. None of the lines were statistically more resistant than G122, a QTL donor and standard resistant check. In a separate study, data collected in NY6020-5 x OR 91G and NY6020-5 x OSU 5613 populations suggest that NY6020-5 has a B7 QTL equivalent to G122. Other researchers have presented evidence that G122 has a B8 QTL equivalent to NY6020. Finally in a mixed linear model study we identified two markers, B181500 and C81200, which should prove useful in breeding for white mold resistance. While the material that we developed does not show significantly higher levels of resistance than the resistant parents, we have transferred the resistance QTL into a bush blue lake background, and the lines derived from this work should have significantly higher levels of resistance than existing commercial cultivars. We also present evidence of a QTL not previously identified in NY6020-5.

Book Synopsis Selection for White Mold Resistance in Pinto Bean by : Henry Terán-Santofimio
Download or read book Selection for White Mold Resistance in Pinto Bean written by Henry Terán-Santofimio and published by . This book was released on 2008 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: White mold (WM) caused by Sclerotinia sclerotiorum (Lib.) de Bary is a devastating disease of common bean (Phaseolus vulgaris L.). Improved germplasm screening and breeding methods are needed to facilitate efforts to increase WM resistance. The objectives of this research were to determine (I) the efficacy of three screening methods (SM) to identify resistance, and (II) the effectiveness of gamete (GS) and recurrent selection (RS) in pyramiding resistance from diverse germplasm. The SM were (i) modified straw-test or cut-stem (CSB), (ii) infected bean flower (IFL), and (iii) infected oat seed (IOS). A 195, ICA Bunsi, Othello, and VCW 54 breeding lines and cultivars were tested using a split plot design with three replicates in 2007 and 2008. The WM disease severity was scored at 16, 23, and 33 days post inoculation (DPI) using a 1 to 9 scale. A novel breeding method, GS was practiced from F1 to F4 in two double-cross populations, Pop I = USPT-WM-1/CORNELL 601//USPT-CBB-1/92BG-7 and Pop II = Chase/I 9365-25//ABL 15/A 195. Thirteen selected F1.5 breeding lines and parents from each population were tested using a randomized complete block design with three replicates in two greenhouse environments. For RS practiced in the same Pop I and II, only highly resistant plants of F1-derived families of each population were used to produce cycles 1 (C1) and 2 (C2). Thirteen S 2 families from each of C1 and C2 and parents (C0) of each population were tested as in the GS. Differences between SM and their interactions with years were significant. The IFL and CSB were consistent and correlated positively (r>0.70, P>0.01). VCW 54 had the highest resistance with the lowest WM scores, followed by A 195. WM scores increased with delayed evaluations. Only 1.2% of families from Pop I and 0.9% from Pop II survived GS by F4. An average of 38% gain in WM resistance was obtained in both populations. Eleven breeding lines of Pop I were equal to the best WM resistant parent 92BG-7, while 12 breeding lines of Pop II were equal to the best WM resistant parents A 195 and I 9365-25. Gain from RS in Pop I was 12% and in Pop II 5% from C0 to C1, but differences between C1 and C2 were not significant (P>0.05).

Available in PDF, EPUB and Kindle. Book excerpt: This book provides insights into the genetics and the latest advances in genomics research on the common bean, offering a timely overview of topics that are pertinent for future developments in legume genomics. The common bean (Phaseolus vulgaris L.) is the most important grain legume crop for food consumption worldwide, as well as a model for legume research, and the availability of the genome sequence has completely changed the paradigm of the ongoing research on the species. Key topics covered include the numerous genetic and genomic resources, available tools, the identified genes and quantitative trait locus (QTL) identified, and there is a particular emphasis on domestication. It is a valuable resource for students and researchers interested in the genetics and genomics of the common bean and legumes in general.
