Distinct variations were found among the studied varieties. Significant variation were observed in term of length of inflorescence, width of inflorescence, number of male flower per inflorescence, number of female flower per inflorescence, sex ratio, % male flower, % hermaphrodite flower ranging from 20.9 cm to 31.9 cm, 11.3 cm to 19.7 cm, 279 to 1,363, 59 to 230.7, 1.25 to 19.63, 50.8% to 94.1% and 5.93% to 49.24%, respectively. The result revealed in all varieties inflorescence position were found terminal and flowers were of pentamerous type. Jarda has the longest inflorescence (31.9 cm). Dasheri has the widest inflorescence (19.7 cm). Male flowers were more than hermaphrodite flowers across the varieties. Amrapali has the highest number of hermaphrodite flower (230.7). Bombay has the highest number of male flowers (1,363) and highest sex ratio (19.63). From this study, it can be inferred that Amrapali will have more fruit set as it has highest number of hermaphrodite flowers. The findings of the study will be beneficial for breeding purpose while developing new varieties of superior quality. Keywords Mango (Mangifera indica); Inflorescence; Hermaphrodite; Sex ratio; Pentamerous Introduction Mango (Mangifera indica L.) is an important tropical fruit belonging to the family Anacardiaceae and is one of the choicest fruit in the world. The common habitats of Nepalese mango diversity are tropical plain home gardens, river gorge locations, and subtropical valley (Subedi et al., 2021). Among fruits mango is considered as the king of fruit due to its unique flavor, taste and scent. Mango is mainly grown in the frost-free areas with very few rainfalls during the time of flowering (Humayun and Babu, 2002). Flowering of mango is detrimental factor in the productivity of mango. In tropical fruits like mango, stems that have spent enough time in rest since the previous flush are able to induce flowers. The most important factor influencing flowering is the time since the last flush (Ramírez and Davenport, 2010). Initiation is the first step for mango to flower which involves cell division and elongation. Mango trees passes through four unique periods of flowering: Swelling of the apical bud, panicle elongation, panicle growth and flowering then fruit set (Lemos et al., 2018). Variability of flowering in mango depends upon variety, tree age, and environmental condition (Palanichamy et al., 2011). Mango grows in almost all area of Madesh province but good quality grafted mangoes of known varietal identity are mostly grown in Sarlahi district. Moreover, research on the performance of those varieties grown in that area are rare. So, it is necessary to assess the performance of the superior varieties grown in that area. Therefore, an attempt was made to study the floral characters of 10 varieties in the mango orchard of Tropical Horticulture Center, Sarlahi district, Madesh province, Nepal.
