Microsatellites markers associated with resistance to flower bud thrips in a cowpea F2 population derived from genotypes TVU-123 and WC36

Breeding for resistance to flower bud thrips (Megalurothrips sjostedti) in cowpea has been hindered by the quantitative nature of resistance. To identify simple sequence repeat (SSR) markers associated with resistance to flower bud thrips that could be used for marker-assisted breeding, a F2 population was generated from a cross between genotypes TVU-123 (resistant) and WC36 (susceptible). The population was evaluated...

Studies on styrene concentration in drinking water and hot beverages in some settings

Water bottles and cups composed of polystyrene also contain non-polymerized styrene. Styrene’s toxicological profile is associated with several health issues for humans. Mainly, the central and peripheral nervous systems are highly disturbed by styrene ingestion. Styrene is also considered to be a carcinogenic agent and has been linked to cancer. The HPLC method was validated through prepared QC samples. The HPLC...

Cost effective medium for in vitro propagation of Tanzanian cassava landraces

Cassava (Manihot esculenta Crantz) is a staple food for over 800 million people in the tropics. However, its production is constrained by an inadequate supply of clean planting materials. Tissue culture carried out in laboratories is one established method for the mass production of clean planting materials. However, the cost of conventional tissue culture is high and the cassava industry would benefit from an...
