Correlation among growth, yield and quality attributes in the indigenous and exotic accessions of Cucumis melo L.

Correlation among growth, yield and quality attributes in Cucumis melo L. were estimated using the randomized complete block design (RCBD). Ninety-six variable lines representing different melon types were used in this study. The correlation study in melon, number of fruits per vine exhibited significant and negative correlation with fruit weight, seed cavity length, rind thickness, fruit length and ascorbic acid content, whereas fruit weight had significant and positive correlation with seed cavity length, fruit length and dry matter content. However, rind thickness recorded positive and significant correlation with ascorbic acid content and shelf life. The total soluble solid content depicted positive and significant correlation with ascorbic acid content. However, it displayed negative and significant correlation with titrable acidity. Titrable acidity showed significant and negative correlation with ascorbic acid content, whereas ascorbic acid content recorded positive and significant correlation with shelf life. Days from sowing to marketable maturity displayed positive and significant correlation with days from sowing to last fruit harvest and fruit weight. However, days from sowing to last fruit harvest revealed positive and significant correlation with shelf life with fruit weight. Node at which first hermaphrodite flower appears displayed positive and significant correlation with fruit weight and titrable acidity. However, it depicted negative and significant correlation with total soluble solids content.
