Potential of cowpea variety mixtures to increase yield stability in subsistence agriculture: preliminary results

Autor: Okonya, J. Maass, Brigitte L.

Cowpea Vigna unguiculata (L.) Walp. is an important leafy vegetable and grain legume in Uganda. Unlike in commercial agriculture, where variety mixtures are known to give higher and more stable yields, the performance of cowpea variety mixtures in subsistence agriculture is little known. Mixtures...

Breeding Leucaena for low-mimosine: Field evaluation of selections

Autor: Bray, RA Hutton, EM Beattie, WM

A breeding program to select low-mimosine lines of leucaena has been in progress since 1970. Selections were evaluated in two field trials at Lansdown. Although the low-mimosine selections did indeed have lower mimosine than the control cultivars, their dry matter yield was also inferior (about t...

Characterization of agronomic traits and markers of recombinant inbred lines from intra-and interracial populations of Phaseolus vulgaris L.

Autor: Welsh, W Bushuk, W Roca, William M. Singh, Shree P.

The value of intra- and interracial populations in common bean (Phaseolus vulgaris L.) needs to be determined in order to create useful genetic variation for maximizing gains from selection, broadening the genetic base of commercial cultivars, and making efficient use of available resources. Five...

Contributions to yield, nitrogen fixation and transfer by local and exotic legumes in tropical grass-legume mixtures in Western Samoa

Autor: Reynolds, SG

Exotic legumes (Calopogonium mucunoides, Centrosema pubescens, Pueraria phaseoloides, Macroptilium atropurpureum) and indigenous legumes (Desmodium heterophyllum, Mimosa pudica, Vigna luteola) were compared for dry matter (DM) and crude protein (CP) production, nitrogen fixation and nitrogen tran...

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...

Green manures for maize-bean systems in eastern Uganda: Agronomic performance and farmers' perceptions

Autor: Fischler, MA Wortmann, Charles S.

Researchers worked with farmers in eastern Uganda to develop alternatives for soil management using crotalaria (Crotalaria ochroleuca), mucuna (Mucuna pruriens var. utilis), lablab (Dolichos lablab), and canavalia (Canavalia ensiformis) as green manures in short-term fallows. The participatory re...
