Breeding for bruchid resistance in common bean (Phaseolus vulgaris L.) : interspecific introgression of lectin-like seed proteins from tepary bean (P. acutifolius A. Gray), genetic control and bruchid resistance characterization.

Creator:

Kusolwa, Paul Mbogo

Abstract:

Interspecific hybridization was initiated between wild P. acutifolius accession G40199 and P. vulgaris to introgress resistance to Acanthoscelides obtectus (bean seed weevil). F1 interspecific hybrids were recovered by embryo rescue and maintained until flowering. Mostly sterile hybrids were backcrossed twice to common bean cultivar ICA Pijao to recover sufficient fertility...

Genetic resistance to white mold (Sclerotinia sclerotiorum (Lib.) De Bary) in scarlet runner beans (Phaseolus coccineus L.)

Creator:

Gilmore, Barbara S.

Abstract:

White mold, caused by Sclerotinia sclerotiorum (Lib.) De Bary, is a destructive yield-limiting disease of common bean (Phaseolus vulgaris L.). Genetic resistance to this pathogen is limited in common bean. Identification of high levels of partial physiological resistance in a genetically cross compatible species, Phaseolus coccineus, is advisable. The objectives...
