Nếp Cút là giống nếp đặc sản của tỉnh Quảng Ngãi, có thời gian sinh trưởng dài và thích nghi lâu đời với vùng sinh thái đầm lầy nước nóng giàu khoáng chất nhưng hiện đã bị thoái hóa nghiêm trọng. Vì vậy, ứng dụng kỹ thuật điện di protein SDS-PAGE để chọn lọc những hạt có hàm lượng amylose thấp và protein cao dựa trên mức độ ăn màu của băng waxy và α-glutelin nhằm rút ngắn thời gian chọn lọc giống. Từ kết quả chọn lọc trong phòng thí nghiệm và ngoài đồng ruộng, đã phục tráng thành công giống lúa nếp Cút với các đặc tính tiêu biểu như: Chiều cao thân dao động trong khoảng 119,1-121,8 cm; chiều dài bông 27,8 - 28,6 cm; số bông/khóm 7,8-8,7 bông/khóm; khối lượng 1.000 hạt 25,1-25,6 g; năng suất thực tế 35-38 tạ/ha; hàm lượng amylose 1,82-1,92%; hàm lượng protein 7,08-7,36% và nhiễm nhẹ với các bệnh đạo ôn, bạc lá, khô vằn và sâu cuốn lá, kháng cao với bệnh đốm nâu và rầy nâu. Kết quả nghiên cứu này góp phần quan trọng cho việc bảo tồn, khai thác và phát triển nguồn gen nếp Cút đặc sản địa phương của tỉnh Quảng Ngãi.
