Abstract:
Kerala enjoys a humid tropical climate where the seedling mango population consists of both mono and polyembryonic types. Twelve distinct polyembryonic types could be located in a survey conducted in the central part of Kerala. The characters of these types were described on the basis of the descriptive bank 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, colour etc.) and floral characters (inflorescence position, shape, size, colour, flower characters etc.) exhibited by the types showed great variation. Qualitative evaluation of their fruits was also conducted. The fruit weight ranged from 70 to 425 grams and nine types produce fruits in bunches. In the two types fruits were juicy and in the 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.
