Abstract: A study was carried out to identify the correlation between vegetative traits, floral characters and yield related attributes with fruit yield and weather parameters in papaya cv. Red Lady Taiwan under South Gujarat conditions at Navsari Agricultural University, Navsari during 2018-19. Results revealed that plant height; stem girth and leaf area had a highly significant and positive correlation with fruit yield in hermaphrodite and pistillate forms of papaya. Yield also expressed a highly significant and positive correlation with insertion height of first fruit in bothviz.,pistillate and hermaphrodite plants. Further, yield attributing characters like number of fruits per plant, fruit weight, fruit diameter and fruit length showed positive and highly significant correlation with yield in both type of plants. With regard to traits like weather parameters, plant height, stem girth and leaf area showed significantly positive correlation with maximum temperature in both the types of plants. Pistillate flowers showed highly significant positive correlation with minimum temperature and barren flowers exhibited highly significant positive correlation with sunshine hours while, misshapen hermaphrodite fruits had a positive and highly significant correlation with maximum temperature. The trait fruit yield showed highly significant positive correlation with minimum temperature and sunshine hours in pistillate and hermaphrodite plants of papaya cv. Red Lady Taiwan.
