DIFFERENTIAL RESPONSE OF MANGO VARIETIES TO EPICOTYL GRAFTING ON COMMERCIAL SCALE
Mango is commercially propagated through vegetative methods due to its heterozygous nature. Epicotyl grafting is a recently standardised method for this crop under Kerala conditions. A study was conducted at Kerala Agricultural University, to ascertain the success of this method in fourteen important mango varieties grown in the State. The varieties included for the study were Alphonso, Bangalora, Banganapally, Bennet Alphonso, Chandrakaran, Imampasand, Kalapady, Mulgoa, Mundappa, Jehangir, Nadasala, Neelum, Prior and Suvarnarekha. The survival percentage was recorded at six months after grafting which ranged from 39.6% in Mulgoa to 84.5% in Kalapady, indicating the great variation in the response of different varieties to this method. Bangalora, Neelum and Mundappa varieties also recorded relatively high survival of the grafts (71.5, 70.8 and 69 percent respectively). In order to compare the growth rate of the grafts, height of the plants was recorded at six and twelve months after grafting. The height of the plants varied from 26.3 cm in Chandrakaran to 36.5 cm in Bangalora during the first observation. At twelve months after grafting, the maximum height was recorded by the Bangalora variety, the value being 78.5 cm and the minimum was in Chandrakaran (62.0 cm). The results of the present study indicated that varieties differ in their response to epicotyl grafting in terms of survival percentage and in the initial growth rate of the resultant grafts.
