BRS FC310: CARIOCA COMMON BEAN CULTIVAR WITH SEMI-EARLY CYCLE, UPRIGHT GROWTH HABIT, AND RESISTANCE TO MAJOR DISEASES

Selection aiming at upright growth habit common bean with carioca type grains

Genetic improvement of common bean, along with the incorporation of technologies and investment in the productive sector has stimulated the grain yield in Brazil to an increase of about 45% in the last 15 years (Conab 2005). However, the pressure to achieve more productive lines, associated to the needs for headway in management and regarding consumer demands in relation to grain type is on the...

Registration of Great Northern Common Bean Cultivar ‘Coyne’ with Enhanced Disease Resistance to Common Bacterial Blight and Bean Rust

Journal of Plant Registrations, Vol. 3, No. 3, September 2009 219 Great northern common bean (Phaseolus vulgaris L.) ‘Coyne’ (Reg. No. CV-287, PI 655574) was developed by the dry bean breeding program at the University of Nebraska Agricultural Research Division and released in 2008. It is named in honor of Dermot P. Coyne, who was the bean breeder at the University of Nebraska for about 30 Regi...

Simple Sequence Repeat Dna Markers Linked with Genes for Resistance to Major Diseases of Common Bean

Dissection of Resistance Genes to Pseudomonas syringae pv. phaseolicola in UI3 Common Bean Cultivar

Few quantitative trait loci have been mapped for resistance to Pseudomonas syringae pv. phaseolicola in common bean. Two F₂ populations were developed from the host differential UI3 cultivar. The objective of this study was to further characterize the resistance to races 1, 5, 7 and 9 of Psp included in UI3. Using a QTL mapping approach, 16 and 11 main-effect QTLs for pod and primary leaf resis...

Identification of Rafd Markers Linked to a Major Gene for Rust Resistance and Indeterminate Growth Habit Using Bulked Segregant Analysis in a Common Bean Cross

Rust, incited by Uromyces appendiculatus^ is a major disease in common bean {Phaseolus vulgaris L,). Plant growth habit is also an important trait. Indeterminate growth habit was first reported to be controlled by a single dominant gene (Fin) (Lamprecht, 1935). Molecular markers such as isozymes, RFLP, and RAPD, have been used to tag genes for many traits, particularly disease resistance in sev...
