Critical values of correlation P < 0.05 and P < 0.01 (df 30) are 0.35 and 0.45, respectively. Sample volume was 32 (8 genotypes × 4 replications).

Traits are as follows: FH, fruit hardness; FM, fruit apparent specific weight; PH, pH of fruit; PA, Pectin; PHA, Phenols; N, nitrogen percent; P, phosphorus percent; K, potassium percent; CA, calcium percent; MG, magnesium percent; NA, sodium percent; ZN, zinc percent; FE, iron percent; FL, fruit length; FD, fruit diameter; EH, end hold; FW, fruit weight; NFB, number of flower in branch and BL, branch length.
