Abstract: The breeding process of high yield,high quality and multi-resistant double-season late indica rice variety Jufengyou 441 was introduced. The main characteristics,yield,quality and resistance of the variety were analyzed. The trial yield was 8 458.5 kg/hm²,which was 6.26% and 3.22% higher than that of the control Xieyou 92 and Xinyou 188,respectively,reaching a very significant level;the growth period was almost the same to the control;the rice quality was awarded 3 grade high quality rice;has moderate resistance to rice blast,resistance to rice false smut,resistance to stripe leaf blight,etc.,the stems are thick,the ears are large and with more grains,and the lodging resistance is strong. The high-yield cultivation techniques and high-yield seed production techniques of this variety were summarized.

Key words: Jufengyou 441, late indica rice, breeding
