A trial was conducted during 2018-19 to study the comparative morphology, phenology and productive potential of different plant types in gynodioecious papaya cv. Red Lady Taiwan in South Gujarat. The experiment was laid out in non-replicated trial and consisted of 200 papaya plants. Results indicated a gradual increase in plant height, stem girth, leaf area and number of leaves from July 2018 to May, 2019. For vegetative parameters, the differences between pistillate plants and hermaphrodite plants were not very sharp. With regard to pistillate plants, the maximum flowers per plant (5.40) were recorded in October, 2018 and the maximum fruits (13) were harvested in May, 2019. Fruit weight was the highest (2.20 kg) in January, 2019 and fruit yield was maximum (18 kg/plant) in April, 2019. Days taken from fruit set to harvesting in pistillate plants varied from 121.0 to 130.0 days and the insertion height of fruit ranged from 81.40 to 90.40 cm. In case of hermaphrodite plants, highest number of flowers (5.10) was noticed in February, 2019. Fruits harvested per plant (11) were maximum in May, 2019 and the fruit yield (22.10 kg/plant) was highest in April, 2019. Hermaphrodite barren flowers per plant ranged from 1.60 to 2.80 with maximum value (2.80) in October, 2018. The number of misshapen fruits per plant was found maximum (5.0) in May, 2019. Days taken from fruit set to harvesting in hermaphrodite plants varied from 146.0 to 155.0 days and the insertion height of fruit ranged from 86.70 to 98.60 cm.
