Morphological and molecular characterization of a large fruited unique coconut accession from Vaibhavwadi, Maharashtra, India

Published on

The morphological and molecular characterization of a large
fruited coconut population was undertaken using twentythree morphological traits, six tender nut traits and eight
fruit component traits. Fruit component analysis of the
nuts of this accession indicated that they have low husk to
nut weight ratio typical of the Niu vai type cultivated in
South East Asia. The microsatellite analysis indicated that
Vaibhavwadi coconut population (MAHT) is generally close
to the South East Asian coconut accessions and has
proximity with dwarf accessions in the conserved
germplasm of India. Though, genetic assignment test did
not identify this accession specifically with any particular
cultivar in the microsatellite database, the probable origin
of this type could be identified as Borneo Tall (60% similarity)
a cultivar which is known to produce large coconuts. It is
suggested to conserve the MAHT in the National Coconut
Gene Bank of India for its utilization in the breeding
