Seed quality traits of the plants may directly or indirectly depend on agro-morphological traits. Thus the determination between agronomical and oil quality characters of the plants may be important for plant scientists. The relation between agronomical and oil quality traits were studied by using Canonical Correlation Analysis (CCA) in peanut genotypes. CCA is a multivariate statistical model that facilitates the study of interrelationships among sets of multiple dependent variables and multiple independent variables. As a result, the canonical correlation between the first canonical variate pair was found as 0.897. Five canonical functions obtained from morphological and agronomical traits, had attributed about 70% from variation in the oil quality traits. It can be concluded that CCA can be used to simplify the relationship between agro-morphological and oil quality traits of the peanut.
