    Abstract/Description
    Cassava farmers are yet to fully exploit its full potential in terms of improvement of livelihood. Forty-five genotypes of cassava genotypes were processed into High Quality Cassava Flour (HQCF). These genotypes were planted in two sets, set 1 comprised 22 clones of β-carotene enriched roots and 3 check clones of white roots and set 2 comprised 18 clones and 2 check clones. The effects of variety on the proximate composition and pasting profile of the flour were investigated. The starch content ranged between 67.1 g/100 g (for 01/1663) and 82.4 g/100 g (for 30572) in set 1 and between 69.6 (01/1560) to 77.8 g/100 g (for Z97/0474) in set 2. Peak viscosity values ranged between 295.6 RVU (rapid visco unit) (30572) and 467.0 RVU (01/1115) across clones in set 1 while for set 2, it ranged from 271.9 RVU (for 01/1404) to 471.3 RVU (for 01/1417). Significant differences (P < 0.05) existed in the proximate composition and pasting properties of the flour from different cassava genotypes investigated. The high peak viscosity exhibited by most genotypes is indicative that the flour may be suitable for products requiring high gel strength and elasticity. The proximate composition compares competitively with values obtainable from conventional clones.

      Cassava production and processing in the Democratic Republic of Congo: COSCA working paper, No 22 

      Nweke, F.; Lutete, D.; Dixon, A.; Ugwu, B.; Ajobo, O.; Kalombo, N.; Bukaka, B. (2000)
      The importance of cassava relative to other crops in the cropping system was almost total; cassava was present in 70% of arable fields; maize and beans or peas were each present in 13% of arable fields and all other crops were present in 4%. Cassava was produced mostly for sale, yet it was not as important around market centers as in remote areas because imported rice and wheat products were easily accessible. Cassava land area was not expanding in many of the villages visited because of low-level ...

      Molecular biodiversity of cassava begomoviruses in Tanzania: evolution of cassava geminiviruses in Africa and evidence for East Africa being a center of diversity of cassava geminiviruses 

      Ndunguru, J.; Legg, J.P.; Aveling, T.; Thompson, G.; Fauquet, Claude M. (2005)
      Cassava is infected by numerous geminiviruses in Africa and India that cause devastating losses to poor farmers. We here describe the molecular diversity of seven representative cassava mosaic geminiviruses (CMGs) infecting cassava from multiple locations in Tanzania. We report for the first time the presence of two isolates in East Africa: (EACMCV-[TZ1] and EACMCV-[TZ7]) of the species East African cassava mosaic Cameroon virus, originally described in West Africa. The complete nucleotide sequence ...
