KẾT QUẢ KHẢO NGHIỆM GIỐNG QUÝT QST1 CHÍN SỚM NHẬP NỘI Ở CÁC VÙNG SINH THÁI

With the aim of screening out promissing varieties of citrus targeted for table consumption, a study on the adatability of introduced cultivars of mandarins has been implemented in traditionally different locations in the North of Vietnam. Primary results conducted from the above mentioned study showed that, among the varieties evaluated including “ Cam Duong Canh” used as control one, QST1 (early introduced cultivar of mandarin) is considered to be promissing presented by wealthy growth, high yield (approximately 20 tons/ha at 6 years after planting in three different ecological regions in Northen Vietnam named Phu Quy-Nghe An, Van Giang-Hung Yen and Cao Phong-Hoa Binh) and slightly affected by main insects and diseases. It is especially mentioned that the quality of QST1 involving seedless fruits is a bit better than that of “Duong Canh” mandarin considered to be one of well known local cultivars, that makes QST1 favourable for fresh consumtion.
