Mixed Model procedure is used in the modeling and estimation of treatment efforts and variance components. It extends the generalized linear model (ordinary ANOVA) by avoiding the restrictive assumption of the error terms in ANOVA through the incorporation of the variance-covariance structure of ...

For quite some time, cassava breeding activities of the International Institute of Tropical Agriculture (IITA) in Uganda were mainly focused on developing genotypes resistant to cassava mosaic disease (CMD), which was the major biotic production constraint since the early 1990s. Although cassava ...

Research on the resistance of cassava to fire is scarce because ordinarily researchers would not set their cassava farms on fire for such evaluation. Stems rendered useless by fire were commonly reported by farmers but no information on root yields and shoot regeneration. This study compared the ...
