Abstract

The correlation coefficient (r) of 41 growth, fruiting and fruit quality characters of Ber was estimated using 24 cultivars. The correlation coefficient indicated that tree height was positively correlated with trunk girth, tree volume, cross trunk sectional area, number of shoots per tree, leaf length: breadth ratio and number of fruits per kg. The photosynthetic efficiency had positive but non-significant correlation with yield. Positive and significant correlation of fruit weight was found with fruit volume, stone length, stone breadth and stone weight. TSS showed negative and non-significant correlation with TSS: acid ratio and ascorbic acid content but it showed positive and non-significant correlation with acidity. The TSS: acid ratio gave positive and significant correlation with ascorbic acid content of fruit flesh.
