Book Chapter 1997

Autor: Hampton, R. Thottappilly, G. Rossel, H.

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...

Leaf appearance in crop plants is an important process involved in canopy development. The environmental control of leaf appearance has not been studied in cowpea [Vigna unguiculata (L.) Walp.]. This study was conducted to determine whether photoperiod has any effect on the rate of leaf appearanc...

Manihot esculenta Cyanogenesis, the ability to produce hydrogen cyanide (HCN), is common to over 2000 plant species. In cassava, two cyanogenic glucosides, linamarin and lotaustralin, are produced in the leaves and stored inside vacuoles. Linamarase, an enzyme capable of hydrolyzing the glucoside...

Manihot esculenta.This paper which is based on information collected as part of Collaborative Study of Cassava in Africa (COSCA) provides information on cassava genotypes cultivated in sub-Saharan Africa. It shows that there is a high degree of turnover in the cassava genotypes cultivated. Farmer...

Twelve cassava genotypes were evaluated in the field in two cropping seasons at two locations in Nigeria for their reaction to cassava mosaic disease (CMD), cassava bacterial blight (CBB) and cassava green mite (CGM), using visual injury scores as the index for resistance. Lowest indices for CMD ...

(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 ...

In vitro-propagated plants of plantain (Musa spp., AAB group) did not manifest consistently superior horticultural performance compared to conventional propagules. Tissue culture plants grew vigorously and taller than sucker-propagated plants, but higher yield was not obtained, probably because o...

The genetics of resistance to rice yellow mottle sobemovirus (RYMV) in O. glaberrima was studied in a 6 parent full diallel cross involving 4 resistant and 2 susceptible genotypes. F1 hybrids resulting from crosses between resistant and susceptible genotypes were susceptible. Susceptibility was c...

Cassava (Manihot esculenta Crantz) contains cyanogenic glucosides which lead to the release of hydrogen cyanide (HCN) after hydrolysis. A study carried out using six cassava populations revealed that the broad-sense heritability for HCN was relatively low at 34.58 and 32.18 percent in roots and l...

Stable as well as adaptable genotypes of high-yielding cassava cultivars, should be developed and made available to farmers, to ensure increases in cassava production in a target region or country in sub-Saharan Africa. As farmer-to-farmer contact is the primary means of diffusion of new crop var...
