Meta-QTL for resistance to white mold in common bean
White mold, caused by the fungus Sclerotinia sclerotiorum (Lib.) de Bary, is a major disease that limits common bean production and quality worldwide. The host-pathogen interaction is complex, with partial resistance in the host inherited as a quantitative trait with low to moderate heritability. Our objective was to identify meta-QTL conditioning partial resistance to white mold from individua...
متن کاملQTL Conditioning Physiological Resistance and Avoidance to White Mold in Dry Bean
white mold with upright architecture has progressed relatively slowly. Cumbersome screening methods, low Physiological resistance is an important component of integrated heritability, and few available resistance sources have strategies used to control white mold [caused by Sclerotinia sclerotiorum (Lib.) de Bary], a major disease of common bean (Phaseolus contributed to the lack of progress fo...
متن کاملComparative QTL Map for White Mold Resistance in Common Bean, and Characterization of Partial Resistance in Dry Bean Lines VA19 and I9365-31
White mold caused by the necrotrophic fungus Sclerotinia sclerotiorum (Lib.) de Bary limits common bean (Phaseolus vulgaris L.) production in temperate climates. Disease resistance has been identifi ed, but breeding is hampered by a paucity of resistance sources and complex inheritance, as numerous quantitative trait loci (QTL) conditioning partial resistance have been found. Our objectives wer...
متن کاملIdentification of QTLs of resistance to white mold in common bean from multiple markers by using Bayesian analysis.
In this study, we identified simple sequence repeat, ampli-fied fragment length polymorphism, and sequence-related amplified poly-morphism markers linked to quantitative trait loci (QTLs) for resistance to white mold disease in common bean progenies derived from a cross between lines CNFC 9506 and RP-2, evaluated using the oxalic acid test and using Bayesian analysis. DNA was extracted from 186...
متن کاملInheritance and QTL Analysis of Field Resistance to Ashy Stem Blight in Common Bean
Ashy stem blight [caused by Macrophomina phaseolina (Tassi) Goid.] can be a serious disease of common bean (Phaseolus vulgaris L.) under drought and high temperature conditions in some regions. The mode of inheritance of valuable sources of resistance is lacking. We studied inheritance of field resistance to ashy stem blight in a recombinant inbred population (’Dorado’ × XAN 176) consisting of ...
