Physiochemical and protein profiling of Bacaurea ramiflora (Burmese grape) an underutilized fruit crop in Arunachal Pradesh

A survey was conducted in the Napit, Pekung and Runne village of East Siang district of Arunachal Pradesh, India during the period 2015–2016 for the documentation on the variability of Bacaurea ramiflora (Burmese grape) in this region. These plants are found wild or in the homestead garden. From the investigation two types of morphotype could be identified in this region (mild acidicand sweet type). Study on its different physicaland quality parameters revealed that the sweetness ranges from 12.5 to 16.5° Brix and the fruit parameters like fruit weight, pulp weight, fruit juice, TSS, total sugar and acidity are found to be significant among the genotypes. However, the biochemical marker (SDS PAGE) revealed monomorphic banding pattern and no variable is found in among the genotypes which can be confirmed using molecular marker in the near future.
