Development of an appropriate breeding scheme for tolerance to Empoasca kraemeri in common bean

Autor: Kornegay, Julia L. Cardona, C.

Significant advances in increasing tolerance to the leafhopper Empoasca kraemeri Ross & Moore in common bean have been obtained using a new breeding scheme where yield under leafhopper attack is the principal selection criterion in the evaluation of progenies. However, to further refine this bree...

Inheritance of resistance to Acanthoscelides obtectus in a wild common bean accession crossed to commercial bean cultivars

Autor: Kornegay, Julia L. Cardona, C.

The bean weevil Acanthoscelides obtectus, is an important storage pest of common beans in Latin America and Africa. A few wild bean accessions from Mexico have been identified as highly resistant to the weevil. One accession, G 12952, was crossed to two susceptible bean cultivars differing in see...

Reactions of selected bean pure lines and accessions to Meloidogyne species

Autor: Mullin, BA Abawi, G.S. Pastor Corrales, Marcial A. Kornegay, Julia L.

Over 150 bean (Phaseolus vulgaris) pure lines and accessions were evaluated in growth chamber and greenhouse trials for reactions to one or more populations of root-knot nematodes (Meloidogyne spp.) collected from Colombia or the United States. Bean pure lines and accessions were evaluated for ro...

Root-knot nematodes associated with beans in Colombia and Peru and related yield loss

Autor: Mullin, BA Abawi, G.S. Pastor Corrales, Marcial A. Kornegay, Julia L.

A survey of root-knot nematodes associated with bean (Phaseolus vulgaris) roots and soils in the major bean production regions of Colombia and Peru was conducted during 1988 1989. Over 150 samples were processed for these parasites, and specimens from more than 100 of the collections were identif...
