Study on flowering behaviour of elite mango cultivars in subtropical conditions of Bihar

Abstract

Flowering is a decisive factor in the productivity of mango. Twenty mango cultivars were studied for the flowering behaviour at Bihar agricultural university, sabour. The perusal of data recorded showed the earliest bud break in cultivar Bombay Green on 19th January followed by Bombai and Zardalu on 26th January. However, SB Chausa, Fazli and Neelum recorded a very late bud break. Maximum numbers of panicles were found in the cultivar Langra (2275) while the minimum number of panicle was found in Neelum (587). Maximum panicle length was observed in SB Chausa (34.5 cm) while minimum was found in Bombay green (17.25 cm) followed by Neelum (20.75 cm). There were differences between cultivars for the date of first flower opening and in the time and duration of peak flowering. There is, therefore, a possibility of carrying out selection for earliness as well as duration of flowering. In terms of the flower types, staminate flowers were first to appear in all the cultivars followed by hermaphrodite one. The cultivar Langra showed maximum percentage of hermaphrodite flower (73.86%) while minimum hermaphrodite flower percentage was found in Swarnarekha.
