Ojiambo, P.S.Twizeyimana, M.Tenkouano, A.Bandyopadhyay, Ranajit[Rapid and mass screening of banana and plantain for resistance to Black sigatoka disease using detached leaf and in vitro plantlets]Rapid and mass screening of banana and plantain for resistance to Black sigatoka disease using detached leaf and in vitro plantlets

Soybean rust, caused by Phakopsora pachyrhizi, is one of the most important constraints to soybean production worldwide. The absence of high levels of host resistance to the pathogen has necessitated the continued search and identification of sources of resistance. In one set of experiments, 178 ...


Twizeyimana, M.Ojiambo, P.S.Ikotun, T.Ladipo, J.L.Hartman, G.L.Bandyopadhyay, Ranajit[Evaluation of soybean germplasm for resistance to soybean rust (Phakopsora pachyrhizi) in Nigeria]Evaluation of soybean germplasm for resistance to soybean rust (Phakopsora pachyrhizi) in Nigeria

Fourteen soybean accessions and breeding lines were evaluated for resistance to soybean rust caused by the fungus Phakopsora pachyrhizi. Evaluations were conducted in replicated experiments in growth chambers using detached leaves and under greenhouse and field conditions. In growth-chamber exper...


Twizeyimana, M.Ojiambo, P.S.Ikotun, T.Paul, C.Hartman, G.L.Bandyopadhyay, Ranajit[Comparison of field, greenhouse and detachedleaf evaluations of soybean germplasm for resistance to Phakopsora pachyrhizi]Comparison of field, greenhouse and detachedleaf evaluations of soybean germplasm for resistance to Phakopsora pachyrhizi

Fusarium stalk rot is one of the most widespread and destructive diseases of maize, and deployment of resistant genotypes is one of the most effective strategies for controlling the disease. Fifty inbred lines and four checks from the breeding program of the International Institute of Tropical Ag...


Afolabi, C.G.Ojiambo, P.S.Ekpo, E.J.Menkir, A.Bandyopadhyay, Ranajit[Novel sources of resistance to Fusarium stalk rot of maize in tropical Africa]Novel sources of resistance to Fusarium stalk rot of maize in tropical Africa

Fusarium ear rot and fumonisin contamination is a major problem facing maize growers worldwide, and host resistance is the most effective strategy to control the disease, but resistant genotypes have not been identified. In 2003, a total of 103 maize inbred lines were evaluated for Fusarium ear r...


Afolabi, C.G.Ojiambo, P.S.Ekpo, E.J.A.Menkir, A.Bandyopadhyay, Ranajit[Evaluation of maize inbred lines for resistance to fusarium ear rot and fumonisin accumulation in grain in Tropical Africa]Evaluation of maize inbred lines for resistance to fusarium ear rot and fumonisin accumulation in grain in Tropical Africa

Soybean rust, caused by Phakopsora pachyrhizi, is an important disease in Nigeria and many other soybean-producing countries world-wide. To determine the geographical distribution of soybean rust in Nigeria, soybean fields were surveyed in the Derived Savanna (...


Twizeyimana, M.Ojiambo, P.S.Sonder, KaiIkotun, T.Hartman, G.L.Bandyopadhyay, Ranajit[Pathogenic variation of Phakopsora pachyrhizi infecting soybean in Nigeria]Pathogenic variation of Phakopsora pachyrhizi infecting soybean in Nigeria
