Abstract
Phenotypic characterization of rice (Oryza sativa L.) provides useful information regarding preservation of
diversity and selection of parental genotypes with superior traits in plant breeding program. The main objective of the
present study was to characterize 13 selected rice genotypes from Kenya and Tanzania based on 7 grain and kernel
traits. Minitab 15.0 software was used to analyze data. The 7 traits showed highly significant differences among the
improved and local landraces. A dendrogram was constructed from data set of mean values of grain and kernel traits
and showed two super clusters; I and II. Principal component analysis revealed that all the seven quantitative traits
significantly influenced the variation in these genotypes.
