In the production of rice in the Mekong Delta region currently, the variety plays an important role in ensuring yield and quality. Local institutes and schools are focusing on applying science and technology to improve the quality of rice varieties, elevating the status of Vietnamese rice. In reality, despite being the country's rice production center, the Mekong Delta region still faces many difficulties in improving the quality of rice varieties. In this region, the official seed system meets about 45% of the demand with over 4 million hectares, planting equivalent to 180,000-200,000 tons of seeds per year; the farmer household system (cooperatives, HTX) produces about 25% equivalent to 90,000-100,000 tons of rice seeds per year; the rest is left to independent farmers. Mr. Nguyễn Trung Trị from Phụng Hiệp commune, Cần Thơ, who has extensive experience in rice production, said that to maintain the quality of export rice, the requirements for seed quality are increasingly stringent. Therefore, only the path of applying science and technology in a comprehensive and synchronized manner can help improve the quality of rice varieties.
