Abstract:

Growth and inflorescences characteristics of 30 mango genotypes were studied during the period of 2017 to 2018.The evaluation of new cultivars adaptation of mango (Mangifera indica L.) provides tools to assist and improve the mango production in different climatic conditions. The study was conducted to evaluate the phenological and reproductive development of different mango genotypes. The variables like total tree height, tree spread, tree girth, leaf length, leaf width, petiole length, Date of panicle emergence, panicle length, panicle width, number of male and perfect flowers, perfect flower percentage and sex ratio were recorded during the period of study. The average tree height (8.36 m), tree spread (8.99 m) and stem girth (103.97 cm)was found to be observed maximum in Sundar Langra. The maximum leaf length, leaf width and petiole length was observed significantly in Alphonso (32.85 cm), Sindhu (10.24 cm) and ArkaAruna (6.28 cm) respectively. Results pertaining to panicle emergence suggest that Malpacharisi, Sendhuram, Arka Aruna and Imam pasandhad very early emergence of panicle (before January).The maximum percentage of perfect flowers per inflorescence was recorded significantly in Sothuparaivadumangai (31.43 %). Among the genotypes PKM 1exhibited significantly maximum sex ratio (hermaphrodite flowers to male flowers) (1:5.43). It is concluded that some genotypes like SundarLangra, ArkaAruna, Sendhuram and Alphonso were superior in most of the traits.
