Vinh orange has been granted Geographical indication registration certificate no. 00012 in Decision no. 386/QĐ-SHTT dated 31 May 2007 of the Director General of National Office of Intellectual Property. As stipulated in this Decision, the orange bearing the geographical indication including the following varieties: “Xã Đoài”, “Vân Du”, and “Sông Con” shall be produced within the territory of the communes of Nghi Diên and Nghi Hoa of Nghi Lộc district; Hưng Trung of Hưng Nguyên district; Nghĩa Bình, Nghĩa Hiếu, Nghĩa Hồng, Nghĩa Lâm, and Nghĩa Sơn of Nghĩa Đàn district; Minh Hợp of Kỳ Hợp district; Tân An, Tân Long and Tân Phú of Tân Kỳ district, Nghệ An province.
In Nghệ An, orange has been produced for ages and especially developed in the 1960s and 1970s. Through generations, local orange producers have developed a kind of orange that is favoured by the consumers and became one of the ten spearhead agricultural products of Nghệ An province. Thanks to its superior quality, the orange from this region has become well-known throughout the country and a specialty of the Nghệ land. Orange has been developed ceaselessly, enhancing its economic value, encouraging the producers to invest and expand the production, especially after the geographical indication registration certificate was granted. However, during the previous research and formulation of the geographical indication “Vinh” orange, the collection of samples to determine the appearance and quality of the orange was limited to 3 varieties planted in 12 communes of 5 districts, as these are the first areas to produce orange in Nghệ An and these are also the core areas of “Vinh” orange production. These limitations do not accurately reflect the practical situation of orange production in Nghệ An province. Therefore, Nghệ An province has developed the V2 variety, a late bloomer variety with the ability to adapt and develop well with geographical conditions of other areas in the province.
The research shows that the appearance and quality of V2 orange are on par with the varieties that were protected, namely Xã Đoài, Vân Du and Sông Con varieties. The natural conditions and production practices of the expanded area have no significant difference and completely consistent with the conditions of the protected geographical area.
The above research serves as a foundation for the amendments of Geographical Indication no. 12 on 16 August 2019 of the Department of Science and Technology of Nghệ An province, with supplements of information regarding V2 variety and expand the geographical area, from 12 communes of 5 districts to 73 communes of 11 districts of Nghệ An province. On 16 October 2019, the Director General of Intellectual Property Office of Viet Nam has issued Decision no. 5004/QĐ-SHTT on amending the Geographical indication registration certificate no. 00012 for “Vinh” orange with the following amendments:
