Field evaluation of six cassava genotypes for resistance to root rot disease was compared with three rapid laboratory methods (whole root inoculation, root slice inoculation, and stem inoculation) for resistance screening. Both the field evaluation and the three laboratory methods separated the v...

Assessment of laboratory methods for evaluating cassava genotypes for resistance to root rot disease
eports of cassava root rot disease from different African countries have increased in recent times. Field studies were conducted from July 1998 to October 1999 to determine a reproducible disease assessment method that would allow the comparison of results from different locations and an evaluati...

Field evaluation of root rot disease and relationship between disease severity and yield in cassava
Geo-referenced surveys were conducted in 2001 and 2003 to assess the prevalence and severity of
cassava bacterial blight (CBB) and cassava anthracnose disease (CAD) in different agro-ecological
zones of Nigeria. A total of 132 fields were visited in 2001 as follow: humid forest (HF) 42, derived
s...
