The genetic improvement of mango (Mangifera indica L.), a native of India, has been largely through selection
among seedling populations or propagating elite clones and such efforts have resulted in the identification and
cultivation of improved commercial varieties. Development of better cultivars by traditional method using
morphological traits, although highly heritable, is slow because of long juvenility and being expensive. Farmers
of Pusa, Bihar have been conserving high levels of intraspecific diversity of mango in old orchards mostly located
along the Gandak River. These orchards are often poorly maintained as revenues obtained are small compared to
income from other farm activities; however these old orchards harbour a highly diverse population of traditional
mango varieties and seedlings, with trees over 80 years old. Hence a survey was conducted in five communities
for documenting the mango diversity found in native landraces. Sixteen superior mango varieties of endemic
value and importance were evaluated for table, sucking and pickling purposes on the basis of physical appearance
and chemical attributes. Out of these, six were found suitable for table, five for sucking, three for pickle and
two for dual purpose (sucking and table). Studies revealed a clone from Bhuskaul community with fruit weight
up to 420.0 g with TSS 27.400B and having very thin stone and maturing by the end of August. The present
study highlights the need for and demands of diversity rich areas of Pusa community in Bihar to conserve and
protect seedling mangoes for the benefit of posterity with high value traits for future promotion. Furthermore,
the characterization work was captured in fruit catalogues and shared back with the farming community, which
might have increased the awareness, interest and appreciation of the available mango diversity and the interest
in the continuation of these old highly diverse mango orchards for home use and to explore the commercial
potential of these orchards and various types.
