Abstract An experiment was conducted at Block "C" of N. M. College of Agriculture, Navsari Agricultural University, Navsari entitled "Correlation of different yield attributing characteristics on the yield of fruits in banana cv. Grand Naine" during the year 2011. The studies consisted of 150 plants of banana cv. Grand Naine for various parameters and their correlation with yield. The experiment was laid out in a non replicated trial for metric and non metric variables. A wide range of variation was observed for vegetative growth parameters of banana at various growth periods viz., leaf length (39.42–157.52 cm), leaf width (19.17–41.09 cm), variation in functional leaf area (0.43–6.06 m2), petiole length (10.28–34.61 cm), variation in functional leaf (6.99–13.27), height of pseudo stem (19.08–198.37 cm), girth of pseudo stem (16.77–59.01 cm), PCA (23.41–277.55 cm2), peduncle length (43.67 cm), peduncle width (14.49 cm), male bud size (31.18 cm length and 30.70 cm girth) showed continuously increased during crop cycle of banana and bunch position was slightly angled. The number of days taken from planting to inflorescence emergence (272.4), days taken from inflorescence emergence to harvesting (101.65) and total crop duration (374.05 days) was recorded during crop cycle of banana plant. The yield attributing characters viz. weight of bunch (21.88 kg), hands per bunch (11.43), fruits on 2nd hand (17.80), hand weight per bunch (1827.45 g), fruits per bunch (202.88), length and girth of fruit (17.61 cm and 10.81 cm, respectively), fruit pedicel length (2.25 cm), fruit pedicel width (1.62 cm), fruit weight (102.58 g) and non metric characters like fruit shape was observed curved (sharp curved) and fruit apex was observed blunt tipped. Coefficient of correlation were estimated for 23 characters which included leaf length, leaf width, petiole length, leaf area, number of functional leaf, pseudo stem height, pseudo stem girth, PCA, days taken from planting to shooting, days taken from flowering to harvest, plant crop cycle, finger length, finger girth, peduncle length, peduncle width, number of hands, fruits per bunch, hand weight, finger weight, fingers per hand, finger weight and fingers per bunch etc. Among these fruit yield exhibited strong positive correlation with leaf area at harvesting time (0.459) and shooting time (0.418), pseudo stem girth at shooting time (0.523) followed by 8th and half MAP (0.476) and harvesting time (0.401), PCA at shooting time (0.521) followed by 8th and half MAP (0.469) and harvesting time (0.398), number of functional leaves at harvesting time (0.402) and shooting time (0.382) and yield attributing characters such as fruits per 2nd hand (0.362), hands per bunch (0.611), fruits per bunch (0.693), fruit weight (0.792), hand weight (0.691), plant crop cycle (0.340) and days taken from flowering to harvesting (0.381).
