Principal factor and cluster analyses were carried out with
15 fodder and seed traits in 100 accessions of Egyptian
clover (Trifolium alexandrinum L.). Principal factor analysis
identified four Principal Components which explained about
69% variability. Varimax rotation enabled loading of similar
type of variables on a common Principal Component
permitting to designate them as fodder yield and seed
yield factors. Genotypes GP 3, 19, 27, 28 and 29 were
found to be better performers on the basis of principal
factor scores with regard to fodder yield and seed traits
when both the principal factors were considered together.
These genotypes may further be utilized in breeding
programmes for improving fodder and seed yield.
Hierarchical cluster analysis resulted into ten clusters
containing one to sixty two genotypes. The best clusters
with regard to fodder and seed characters were C II, VII
and IX. The results of cluster and principal factor analyses
were in agreement.
