The plant height is 96 cm, the plant shape is moderate, the plant is short, the population is neat, the flag leaf is straight, the growth is luxuriant, and the color changes well at the mature stage. The number of effective panicles per mu is 197000 ears, the ear length is 19.4cm, the total grains per ear is 113grains, the seed setting rate is 90.1%, and the 1000-grain weight is 27.7g. Resistance: Rice blast 7, bacterial blight 3, brown planthopper 9. Main indicators of rice quality: head rice rate 71.4%, aspect ratio 1.7, gel consistency 100 mm, amylose content 1.8%.

Yield performance: in 2001, participated in the regional trial of single season late japonica group in the middle and lower reaches of the Yangtze River, the average yield per mu was 527.61 kg, which was 4.18% lower than that of Xiushui 63 (extremely significant); in 2002, the average yield per mu was 552.06 kg, 3.21% lower than that of Xiushui 63 (significant). The average yield per mu in the two-year regional trial was 540.42 kg, which was 3.67% lower than that of Xiushui 63. In the production test in 2003, the average yield per mu was 524.47 kg, which was 2.52% lower than that of the control Xiushui 63.

Key points of cultivation techniques: 1, cultivate strong seedlings: according to local planting habits and Xiushui 63, sow at the same time, 40 kg per mu of seedling field, seedling age no more than 40 days; 2, transplanting: 20, 000 holes per mu, 2-3 grain seedlings per hole, about 50, 000 mu of basic seedlings; 3, fertilizer and water management: 17.5kg nitrogen fertilizer per mu, basal fertilizer, tiller fertilizer, the proportion of panicle fertilizer is 4:3:3. Water slurry management should pay attention to keep the soil moist in the later growth stage in order to maintain root activity; 4. Control of diseases and insect pests: pay attention to the control of rice blast.

Approval opinion: after examination, the variety conforms to the national rice variety approval standard and has been approved. The variety has moderate ripening period, average yield, susceptibility to rice blast, medium resistance to bacterial blight, good processing quality and waxy rice. It is suitable for planting single cropping late rice in the areas with light incidence of rice blast in Zhejiang, Shanghai, Jiangsu, Hubei and Anhui provinces.
