Rice yellow mottle sobemovirus is identified as the most destructive viral disease in lowland and upland rice. In this study, the mode of inheritance of resistance to a prevalent RYMV strain in Uganda was determined for resistant lines (upland NERICAs 8, 11, 12, 13 and Gigante (an O. sativa lowland variety) crossed with susceptible lines (lowland NERICAs 4, 6, 10 and IR64 (an O. sativa lowland variety)) in a full diallel mating design. Segregating F2 progeny were planted in field and screen house in -lattice design and inoculated by standard mechanical procedures. Reciprocal effects were...

The 2 insects pests, stem borers (Busseola busca) and maize weevil (sitophilus zeamais) are very destructive grain pests, hard to control, and cause huge economic losses. The aim of this study was to determine the mechanisms of stem borer resistance in selected weevil resistant inbred lines and determine their combining ability as well as the correlation between stem borer resistance and weevil resistance. The research was conducted at National Crop Resources Research Institute's (NaCRRI) main station in Namulonge, central Uganda. The genetic material used include 4 inbred lines resistant to...
