Last Updated: 2024/11/05, The main results are as follows: (1) Variety source: this variety is a new medium indica late maturing hybrid rice variety Luhui 17, a restorer line used in rice sorghum, Sichuan Academy of Agricultural Sciences, and II-32A, a male sterile line with high outcrossing rate. For the current key promotion portfolio of Sichuan Province, it was included in the promotion plan of Sichuan Province and national key scientific and technological achievements in 1999. (2) characteristics: the total growth of the combination was 151.5 days, which was 2.4 days longer than that of Shanyou 63. The plant height was 114.87 cm, the ear length was 25.74cm, and the grain per ear was 150cm.

For the current key promotion portfolio of Sichuan Province, it was included in the promotion plan of Sichuan Province and national key scientific and technological achievements in 1999.

(2) characteristics: the total growth of the combination was 151.5 days, which was 2.4days longer than that of Shanyou 63. The plant height was 114.87 cm, the ear length was 25.74cm, the grain per panicle was 150g, the full grain was 130g and the weight of 1000 grains was 27.5g. The plant grows neatly, the cold tolerance is strong at the seedling stage, the growth is prosperous, the tillering ability is in the middle and upper, the panicle rate is high, the lodging resistance is strong, the panicle layer is neat, and the color is good in the later stage. In the second session of the rice fragrance cup selection of high quality rice in Sichuan Province, it was rated as a high quality rice combination and won the "Rice fragrance Cup". The resistance to rice blast was significantly stronger than that of the control.

(3) yield performance: the average yield per mu in 1996-1998 was 580.68 kg per mu in the provincial and regional trials, which was 3.85% higher than that of the control, and more than 7% higher than that of the production test and demonstration control. The high yield was demonstrated in Nanjiang County in 2000, and the high yield record of Sichuan Pingba hilly area with a yield of 821 kg per mu was accepted on site.

(4) main points of cultivation techniques: ① sowed early in time to cultivate strong seedlings. ② is reasonably close planted with about 15000 holes per mu and 2 grains per litter. ③ fertilized reasonably, the combination was resistant to fertilizer and lodging, and should be increased by an appropriate amount of available fertilizer to promote early tillering and multiple tillers. In the area where ratooning rice is stored in ④, topdressing and promoting bud fertilizer can promote the high yield of ratooning rice with multiple panicles. ⑤ pays attention to the prevention and control of diseases and insect pests.

(5) suitable planting area: suitable for planting in medium rice planting area below 800 meters above sea level.
