Abstract

This study was carried out to observe the yield and yield components of cowpea cultivars available and cowpea lines, which are grown in nine local areas in Turkey. The study including two cultivars and nine ecotypes, was carried out with randomizes block design with three replications in 1996-1997. Significant differences were observed between the cultivars as in the seed yield, biological yield and vegetation time, according to the two years' combined results. The data indicate great variation within the cowpea, regarding all characters. Factor analysis based principal component (PCA) showed two factors, representing 99.13 % of the total variation. PC1 explaining 98.69 % of the total variance is highly correlated with seed and pod size factors. PC2 may be considered as the time of vegetation time and yield per plant. Eleven examined cultivars were separated in two groups by factor analysis and cluster analysis.
