Studies of Correlation Co-Efficient for Different Physical and Chemical Fruit Parameters of Ber (Ziziphus mauritiana Lamk)

The present investigation was carried out at Department of Fruit Science, college of Horticulture, Banda University of Agriculture & Technology, Banda (UP) during 2019-20. Phenotypic correlations were worked out among twenty-four characters of ber to know the nature of association existing among the characters. Correlation among the quantitative characters were worked out. Fruit length showed significant and positive correlation with fruit width (0.444*) and significantly negative correlation noted with TSS (-0.448*). Fruit weight showed significant and positive correlation with specific gravity (0.985**) and non-significant positive correlation with stone width, stone weight and TSS, ascorbic acid, protein, sugar nonsignificant negative correlation. Stone length exhibited significant and positive correlation with stone width (0.533**) and stone weight (0.918**). Stone width showed significant and positive correlation with stone weight (0.815**). Association obtained during the study can be used while making selection, a method of crop improvement in ber or breeding programmes.
