The original name of the rice variety Fengyou 191 is Fengyuan A/191.

Characteristics: This variety is an indica three-line hybrid rice. Grown as a double-cropping late rice in the middle and lower reaches of the Yangtze River, its average whole growth period is 121.7 days, 0.6 days later maturing than the control Shanyou 46. Plant height is 97 cm, plant and leaf form is good, the population is uniform, the flag leaf is erect, growth is luxuriant, and color turns well at maturity. The number of effective panicles per mu is 182,000, panicle length is 23.3 cm, total grains per panicle is 124.2, seed setting rate is 82.1%, and 1000-grain weight is 30 g. Resistance: rice blast grade 9, bacterial leaf blight grade 5, brown planthopper grade 9. Main grain quality indicators: head rice rate 53.1%, length-to-width ratio 2.9, chalkiness rate 39.5%, chalkiness degree 11.7%, gel consistency 47 mm, amylose content 21.5%.

Yield performance: In 2001, it participated in the regional trial of the late indica medium-late maturing high-quality group in the middle and lower reaches of the Yangtze River, with an average yield of 495.29 kg per mu, 4.21% higher than the control Shanyou 46 (extremely significant); in 2002, it continued in the high-yield group trial, with an average yield of 470.81 kg per mu, 6.98% higher than the control Shanyou 46 (extremely significant); the two-year regional trial average yield was 482.35 kg per mu, 5.59% higher than the control Shanyou 46. In 2003, the production trial average yield was 465.82 kg per mu, 1.39% lower than the control Shanyou 46.

Key cultivation techniques: 1. Raise strong seedlings: sow at the same time as Shanyou 46 according to local planting habits, with a sowing rate of 8-10 kg per mu; 2. Transplanting: seedling age should not exceed 30 days, planting density is 16.7´20 cm, with 100,000 basic seedlings per mu; 3. Fertilizer and water management: base fertilizer and organic fertilizer should dominate, with heavy application early, accounting for about 65% of the total fertilizer application, early application of tillering fertilizer, and later fertilizer application depending on the seedlings. Moist management during the grain-filling stage, do not drain too early; 4. Pest and disease control: pay special attention to controlling rice blast, and pay attention to controlling bacterial leaf blight.

Approval opinion: After review, this variety meets the national rice variety approval standards and has passed approval. This variety has a moderate maturity period, relatively high yield, is highly susceptible to rice blast, moderately susceptible to bacterial leaf blight, and has average grain quality. It is suitable for planting as double-cropping late rice in areas with light occurrence of rice blast in central and northern Guangxi, central and northern Fujian, central and southern Jiangxi, central and southern Hunan, and southern Zhejiang.
