Physicochemical and functional characteristics of cassava starch in Ugandan varieties and their progenies

  Due to poor root quality traits in improved, disease resistant cassava (Manihot esculenta Crantz.)  varieties and hence low acceptability among farmers, a study was undertaken to improve these varieties by crossing them with disease susceptible, farmer preferred local landraces. Five improved varieties and four local landraces were used and hybridisations among them were made in a poly-cross nursery...

Pollen behaviour and fertililization impairment in Bambara groundnut (Vigna subterrenea [L.] Verdc.)

  Two field experiments were conducted in April and August, 2007 cropping season at the Department of Crop Science research farm, University of Nigeria, Nsukka, to evaluate the pollen germination potentials and the pollen tube growth of thirteen bambara groundnut cultivars. The harvested pollen grains were exposed for 0, 5, 10 and 15 min durations to ambient conditions before in...
