Book Chapter 1997

Autor: Monti, L. Murdock, L. Thottappilly, G.

Several applications of biotechnology have been successfully used recently in cowpea. A molecular map of cowpea has been constructed using RFLP markers, and this has already facilitated the localization of certain quantitative trait loci; gene chromosome localization using in situ hybridization i...

Cowpea crops are susceptible low more than 20 viral diseases. Some of the most destructive viral pathogens are transmitted from one plant generation to the next through the seed, and thus are generally disseminated to most cowpea-producing regions of the world. Seedborne cowpea viruses, after est...

Five potyvirus isolates from various cowpea-producing areas (Guinea and Sudan savannas and forest zones) in Nigeria were identified by serology and infectivity tests as BlCMV (Isolates IT15, IT16 and WC) or as CAMV (isolates IT11 and ZARIA) and compared with the standard isolate of blackeye cowpe...

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...

Meristem-tip culture is being used to eliminate viruses from plants. The fact that some viruses are easier to eliminate than others has been utilized in thermotherapy and chemotherapy, along with meristem-tip culture, to increase the efficacy of disease elimination. Tissue culture materials are c...
