Abstract: A study was carried out to assess the variability and to identify promising jackfruit types in selected firm fleshed jackfruit types available in Kasargod district. Around 400 jack trees in farmers field was surveyed and characterized based on IPGRI descriptor. The variability of selected 7 types such as KJ 121 (fruiting more than thrice in a year), KJ 182 (clustering habit), KJ 185 & KJ 186 (early ripening), KJ 224& KJ 356 (high TSS content) and KJ 397 (gumless nature) were studied for 2 seasons (2015-16 and 2016-17). The results revealed that, the mean number of fruits per tree varied from 15 to 218.5 and the mean fruit weight varied from 2.08 to 9.17 Kg. Jack fruit types, KJ 224 and KJ 356 showed consistent yield with 49 and 74 fruits per tree per year respectively. The highest TSS content and total sugar percentage were recorded by KJ 182(31.19^oB) & (24.83 %) followed by KJ 356 and KJ 224.
