/phenolics/ascorbic acid system in antioxidant defense and make the flower more vulnerable to oxidative stress ( Takahama and Oniki, 1997 ). Plant tissue color is easily obtained with a portable colorimeter and several studies showed that there is a strong correlation
treatment means. Spearman's coefficients of rank correlation were used as a measure of correspondence between cultivar ranking in each pair of experiments. Pearson correlation coefficients were used as a measure of the strength of association of disease
quantitative parameters for the 82 accessions of A. andraeanum Hort. and the Shapiro-Wilk W test ( NCSS, 2001 ) was used to determine whether each parameter was normally distributed. Pearson’s product moment correlations ( NCSS, 2001 ) were used to determine
and/or breeding lines of MGs V and VI and to analyze the trait correlations, to help the identification and development of adapted superior edamame cultivars with desired traits for the United States. Materials and Methods Plant materials and field

genetic factors that lead to variations in postharvest storability and quality among pumpkin cultivars. Previous studies have indicated a correlation between pumpkin perishability and pulp components during storage ( Hurst et al. 1995 ). Liu et al. (2007
