The ICAR-National Research Centre for Grapes, Pune under Indian Council of Agricultural Research (ICAR), New Delhi was established on 18th January 1997 at Manjari Farm, Pune. The development of new varieties suitable for Indian climatic conditions is one of the major research focus of the center. Considering the market demand, emphasis was on development of colored varieties with naturally bold berries, loose bunch and resistant to pests and diseases. In recent years, the institute has released two black varieties, namely Manjari Shyama and Manjari Medika for table and juice purpose, respectively. To showcase these two varieties to the targeted growers, ICAR- National Research Centre for Grapes and Society for Advancement of Viticulture and Enology (SAVE) organized a Grape day on 12th February, 2020.
A total of 225 farmers from various grape growing regions of Maharashtra viz, Sangli, Nashik, Solapur and Pune were attended the program. The field visit was arranged for the participants during which the detailed information about the special features of the varieties were explained. The field visit was followed by interactive session with the grape growers. During the interactive session, Dr. R G Somkuwar, Director, NRCG briefed about the efforts of NRC grapes in various varietal development program. He also emphasized on prospects of Manjari Shyama and Manajari Medika, newly released varieties, in current market scenario.
