Study on the fruit characters and yield potential of different types of mandarin (Citrus reticulata L Blanco) orange gardens in Lower Dibang Valley district of Arunachal Pradesh

The present investigations were undertaken to know the present status of the mandarin orange gardens of Lower Dibang Valley district of Arunachal Pradesh. A baseline survey was done prior to the investigation and likewise twenty four gardens were selected randomly from the region and grouped into three categories viz small, medium and large. Observations were taken on fruit characters and yield potential of the gardens. It was observed that among the different types of gardens small gardens proved best in terms of fruit characters and yield potential of the plants. The yield is a complex character which is dependent directly or indirectly on different yield attributing and fruit characters. Higher fruit number per plant and higher fruit weight directly attributed to higher yield performance of the small gardens.
