Palmyra palm (Borassus flabelliferL ) or commonly called Taad or Tarh is a palm tree of the Sugar palm group. It is an important multipurpose tree of great utility. There is a rich genetic diversity of palmyrah in Bihar, but no database is available regarding Palmyra. Thus a study was undertaken to study the variability in Palmyra for their plant morphological traits and yield parameters. Sample was collected during fruiting season and plants with diverse in nature for tree characteristics and fruit yield. | Study of genetic variability of palmyapalm on the basis of tree morphology and yield parameters in Bihar
