This book was released on 2007 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: White mold, caused by Sclerotinia sclerotiorum (Lib.) de Bary, results in severe losses in the production of common bean, Phaseolus vulgaris, especially snap bean varieties. Advanced backcross QTL analysis was used to identify quantitative trait loci for resistance to white mold in an interspecific cross of P. vulgaris and P. coccineus and to select resistant, well-adapted germplasm for development of superior common bean cultivars. A population of 115 BC2F4 lines from a cross of snap bean cultivar OR 91G x runner bean accession PI 255956 was genotyped using amplified fragment length polymorphism (AFLP®) and simple sequence repeat (SSR) markers. Corresponding BC2F5 progeny were evaluated for resistance to white mold in a greenhouse straw test and for tolerance to oxalate in a laboratory test. BC2F6 lines were then tested for resistance under field conditions. Single factor analysis of variance identified 29 marker loci contributing to response in at least one phenotypic test. One QTL conditioning 6% of the variance for field resistance was identified by composite interval mapping on linkage group 09, anchored to the consensus linkage group b09 by SSR loci. Significant deviation from expected segregation ratios was observed at all but 3 SSR loci and at all but 7 AFLP® loci (p

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.

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).

This book was released on 2014 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Snap bean (Phaseolus vulgaris L.) is an important crop to diversified vegetable production in the Great Lakes Region of the United States, but an aphid-transmitted virus disease complex threatens sustainable production. The component viruses include the potyviruses Clover yellow vein virus (ClYVV) and Bean yellow mosaic virus (BYMV) that are acquired and transmitted rapidly by dispersing aphid vectors. This situation necessitates the identification, introgression, and deployment of plant virus resistance alleles to achieve effective and ecologically sensitive control. Genetic variation for resistance to ClYVV was characterized at the phenotypic and molecular genetic levels. The relationship of three previously putative independent resistance alleles, cyv, desc, and bc-3 was resolved into an allelic series at the Bc-3 locus where the strain and species-specific resistance spectrum was allele specific. Given previous advances, this pathosystem presented an immediate candidate gene, P. vulgaris eIF4E (PveIF4E), as the molecular basis for resistance. A complete association between specific non-synonymous single nucleotide polymorphisms (SNPs) and virus resistance led to the identification of the putative molecular determinants for resistance to ClYVV and Bean common mosaic necrosis virus (BCMNV) strain NL 3 D. PveIF4E allele specific assays were developed for rapid introgression of bc-3 and the novel bc-32 allele into bean breeding programs. Phenotypic evaluation and the allele specific assays were used to further characterize ClYVV resistance in a large and representative sample of common bean genetic diversity. The result was the identification of novel ClYVV resistance in all major market classes, and the validation of the use of the assays for allele mining in germplasm collections. These efforts also lead to the phenotypic identification of ClYVV resistance alleles at independent loci, and established a model for resistance that now includes By-2 and the bc-u, bc-22 combination. The novel and highly efficient genotyping-by-sequencing (GBS) method was adapted to common bean and used to map the position of the By-2 allele for resistance to BYMV and ClYVV. By-2 was mapped to within a 974k kb region on the distal portion of chromosome 2. This effort generated genomic resources for fine mapping and assays that were also validated for marker-assisted selection.

Book Synopsis Investigating the Genetic Control of Fusarium Root Rot Resistance in Snap Beans by : Abigail R. Huster
Download or read book Investigating the Genetic Control of Fusarium Root Rot Resistance in Snap Beans written by Abigail R. Huster and published by . This book was released on 2016 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Root rot diseases are a major constraint to bean (Phaseolus vulgaris L.) production around the world. Both snap beans and dry beans are affected. Root rot diseases can be caused by a variety of pathogens; however, Fusarium solani is a common causal agent. Fusarium root rot is a primary yield limitation of snap bean production in Oregon. Cultural control methods are ineffective and the pathogen will be present at the end of one season of production on previously clean land, indicating the need for genetic resistance. In order to address this need, a diversity panel of 148 snap bean varieties (the BeanCAP Snap Bean Diversity Panel) was evaluated for resistance to Fusarium root rot in Oregon. Morphological traits potentially involved in root rot resistance were also evaluated. Genome-wide association studies were conducted to locate SNPs associated with Fusarium root rot resistance, aboveground biomass, adventitious roots, taproot diameter, basal root diameter, deepest root angle, shallowest root angle, root angle average, root angle difference, and root angle geometric mean. Significant associations were located for all traits evaluated, including associations with root rot resistance on Pv02, Pv08, Pv09, and Pv10. Genomic estimated breeding values based on BLUPs and BLUEs were generated for each variety and trait. In order to investigate the genetic architecture of the diversity panel principal component analysis, a kinship heat map, and a neighbor-joining phylogenetic tree were generated. The first principal component axis separated varieties by center of domestication, while the second principal component axis separated European extra-fine beans from other Mesoamerican varieties. Kinship analysis demonstrated an average similarity coefficient between varieties of 0.67. The phylogenetic tree indicated two separate derivations of snap beans with extensive subsequent recombination. In this study we also converted previously published SNP markers associated with resistance to root rot diseases in snap bean into user-friendly INDEL and KASP markers to aid in the implementation of marker-assisted selection for resistance to root rot in snap bean.

This book was released on 1979 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies to evaluate resistance in snap beans, Phaseolus vulgaris L. to adult western spotted cucumber beetles, Diabrotica u. undecimpunctata Mann. were conducted in greenhouse cages, field cages, field plots, and in temperature controlled cabinet in the laboratory. Results showed that there were differences in susceptibility to adult feeding injury between 12 selected snap bean cultivars. Spartan Arrow, Green Isle, Resistant Cherokee Wax, Itasca, and Oregon 1604 showed a higher level of resistance, whereas Blue Crop, Blue Max, Green Ruler, Bush Blue Lake, and Bush Hort. #4 were most susceptible. Beetle injury affected bean grades and damage by beetles exceeded the one percent level accepted by processors for grade A beans in all cultivars tested. Adult beetles preferred young succulent leaves of the cotyledonous stage. In all cultivars studied more than 5O% of the seedlings were damaged, however damage during the cotyledonous stage had the least effect on yield except when complete defoliation and death of seedling occurred.
