Knowledge of the genetic relationships and variability among cultivated germplasm is important for facilitating the transfer of useful genes and maximizing the use of available germplasm resources. In this study, random amplified polymorphic DNA (RAPD) markers were used to assess genetic diversit...

(ACMV) were assessed in shoots regenerated from single-node cuttings of three cassava genotypes differing in resistance to ACMV. Plants of the moderately resistant TMS 4(2)1425 and susceptible TMS 60506 did not recover from the disease as rapidly as those of the resistant TMS 30001, Recovery was ...

The effect of mixed infection of cowpea aphid-borne mosaic (CAMV) and cucumber mosaic (CMV) viruses on cowpea yield varied with the resistance levels of cowpea lines, since there was a strong interaction between the latter and virus infection types atP ≤ 0.01. In cowpea line TVu 3629, with low re...

The survivorship, fecundity and development time (egg to adult) of Cicadulina storeyi China, C. arachidis China and C. ghaurii Dabrowski were studied at three constant temperatures (20, 25 and 30 .C). Additional tests were conducted to descriptionbe maize streak virus (MSV) transmission by C. ara...

Okra mosaic virus (OMV, tymovirus group) was isolated from Indigofera spicata plants growing at the International Institute of Tropical Agriculture (IITA) in Ibadan, Nigeria. Its identity was established on the basis of particle morphology, analysis of viral coat protein and nucleic acid and Indi...
