Polyembryonic Varieties
Almost 40 polyembryonic varieties of mango have been imported from Australia to
develop homogeneous and true type resistant / tolerant root stock against biotic and a
biotic stresses. The preliminary studies revealed that a mango variety 13-1 has
tolerance against excessive salts in the soil but it is susceptible to Sodium (Na). On the
other hand, Carabao Lamao and Bullock Hearts have been found tolerant against
Mango Sudden Death (MSD) while traditional inoculations of Ceratocystis sp. were
made on the experimental plants. However, further studies for the final screening of
these two varieties against MSD are underway.
