Rao, Idupulapati M.Miles, John W.Granobles, Juan Carlos[Differences in tolerance to infertile acid soil stress among germplasm accessions and genetic recombinants of the tropical forage grass genus, Brachiaria]Differences in tolerance to infertile acid soil stress among germplasm accessions and genetic recombinants of the tropical forage grass genus, Brachiaria

Cassava (Manihot esculenta Crantz) is a clonally propagated staple food crop in the tropics. Genomic selection (GS) has been implemented at three breeding institutions in Africa to reduce cycle times. Initial studies provided promising estimates of predictive abilities. Here, we expand on previou...

Random amplified polymorphic DNA (RAPD) variation is being used increasingly to characterize germplasm collections. However, the technique has limitations due to the lack of reproducibility of results under certain conditions. Here we review some of the literature on the factors that are mainly r...

Several differnt methods using different numbers of plants and observations have been used for characterisation of germplasm. In this study two different observation strategies for characterisation were tested in order to determine the minimum number of observations and plant per accession whilst...

The rumen degradation and gas production characteristics (methane, carbondioxide) of leaves of 20 accessions of multipurpose trees (MPTs) from six genera: Acacia, Cajanus, Chamaecytisus Link, Erythrina, Leaucaena and Sesbania and some poisonous plants were investigated in vitro and in sacco in ru...

Reports results of two experiments conducted to evaluate a collection of Gliricidia sepium for initial growth and mulch production and to determine the effect of planting density on the establishment and subsequent production of Gliricidia.

Sesbania, particularly S. sesban species, grow naturally in many parts of Africa where they form natural browse. Productivity of Sesbania as animal feed is widely limited by soil acidity and low In this study, eighteen ILCA accessions of S. sesban and two of S. goetzei, all but two from Africa, w...

Tolerance of Sesbania to aluminium and low phosphorus in soils and nutrient solution]Screening forage and browse legumes germplasm to nutrient stresses: III. Tolerance of Sesbania to aluminium and low phosphorus in soils and nutrient solution

The cassava core collection was selected to represent, with minimum repetitiveness, the potential genetic diversity of the crop. The core (630 accessions) was chosen from the base collection (over 5500 accessions) on the basis of diversity of origin (country and geographic), morphology, isozyme p...
