Potential of cassava starch from TME 419 as suitable gelling agent in micropropagation of cassava (Manihot esculenta Crantz)

Cassava starch from nine varieties, namely, NR 8082, TMS 97/2205, TMS 97/0162, TMS 92/0057, TMS 98/0505, TMS 92/0326, TMS 30572, TMS 82/0058, and TME 419 were evaluated for their suitability as gelling substitute to conventional gelling agents (gellan gum and agar) in medium using cassava shoot tips and nodal segments as explants. Explants were seeded singly into a 15 ml cassava multiplication medium gelled either in...

Evaluation of Tanzanian maize germplasms for identification of resistant genotypes against maize lethal necrosis

Experiments were conducted in season 2014B at Naivasha maize lethal necrosis screening facility to evaluate Tanzanian maize germplasms for resistance to maize lethal necrosis (MLN). One hundred and fifty-two maize landraces and 33 inbreed lines were artificially inoculated with maize chlorotic mottle virus and sugarcane mosaic virus isolates in two trials arranged in a completely randomized design (CRD) and two...
