Genetic variability in shoot and root characteristics among 20 broad-based cassava genotypes was studied in four agroecological zones in Nigeria to determine its effects on root yield. Seventeen agronomic parameters were evaluated on a plot size of 40 m2, at spacing of 1x1 m in a Randomized Compl...

Genetic variability in cassava as it influences storage root yield in Nigeria
The associations among different traits and their direct and indirect influence on yield using the path analysis and correlation procedures were examined in 20 broad-based cassava genotypes to understand how inter-character relationships influences root yield. Field evaluation was carried out in ...

The aim of this study was to evaluate the post-harvest survival of Colletotrichum gloeosporioides f. sp. manihotis on infected cassava materials. Infected stem cuttings from 5 cassava cultivars 88/01084, 88/01983, 91/00395, 91/00317 and 91/00052, incubated at 25±2°C for 8 months, showed a signifi...

Cassava (Manihot esculenta Crantz) is a staple food for over 600 million people in the tropics and sub-tropics and is increasingly used as an industrial crop for starch production. Cassava has a high growth rate under optimal conditions but also performs well in drought-prone areas and on margina...

Xanthomonas axonopodis pv manihotis (Xam) is the causal agent of cassava bacterial blight (CBB)worldwide. To develop a well-organized disease management policy in a country, the diversity of pathogenspopulation must be known. The bacterial populations of Xanthomonas axonopodispvmanihotis (Xam)obt...

Cassava (manihot esculenta Crantz), a major food crop in tropical lowlands, is susceptible to many pathogens that decrease the yields. The most common biotic constraint to its production worldwide is Cassava Bacterial Blight (CBB) caused by Xanthomonas axonopodis pv. Manihotis (Xam).

A countrywide survey on cassava constraints in D.R. Congo was initiated in 2002 and completed in 2004 with the aim of assessing the health status of cassava in various agro-ecological zones of the 11 provinces of the country. The survey permitted to update the list of diseases and pests that cont...
