Kerala enjoys a humid tropical climate where the seedling mango population consists of both mono and poly embryonic types. Twelve distinct polyembryonic types could be located in the central part of Kerala. The characters of these types were described on the basis of the descriptive blank for mango. The trees located belonged to the age group of 10 to 80 years and all except one exhibited regular bearing habit. The vegetative characters (leaf shape, size, color etc.) and floral characters (inflorescence position, shape, size, color, flower characters etc.) exhibited by the types showed great variation. Qualitative evaluation of their fruits was also conducted. The fruit weights ranged from 70 to 425 grams and nine types produce fruits in bunches. In two types, fruits were juicy and in others the fruits were of medium table qualities. Seeds of the located types were collected and sown to test the occurrence of polyembryonic character. The number of seedlings produced per seed ranged from two to six. Further evaluation of these types is being conducted for exploring the possibilities of utilising them for breeding purposes in the future.
