Fuyou 98 (formerly known as Qingjiang No. 2) (Rice)

Breeding unit: Hubei Qingjiang seed Industry Co., Ltd., Rice and Wheat Institute of Fujian Academy of Agricultural Sciences

Source of variety: Foy A × 98-4

Characteristics: this variety belongs to a medium indica late-maturing three-line hybrid rice combination with a full growth period of 151days, which is similar to that of the control Ⅱ you 58. The plant height is about 111 cm, the growth potential is strong, the plant grows neatly, the plant leaf shape is moderate, the ear grain structure is coordinated, and the late ripening phase is good. The effective panicle per mu is 18-210000 ears, the panicle rate is about 60%, the ear length is 22-24 cm, the total grains per panicle is 140-150 grains, the seed setting rate is about 85%, and the 1000-grain weight is about 29 grams. Rice blast is grade 3. The main indicators of rice quality: head rice rate 57.8%, length-width ratio 2.7, chalky rice rate 46%, chalkiness 7.7%, gel consistency 46 mm, amylose content 22.00%.

Yield performance: in 2002, participated in the Wuling mountain medium indica regional trial, the average yield per mu was 552.88 kg, which was 4.5% higher than that of the control Shanyou 63 (extremely significant); in 2003, the average yield per mu was 578.08 kg, 3.87% higher than that of the control Ⅱ you 58 (extremely significant); the average yield per mu in the two-year regional trial was 565.48 kg. In the production test in 2003, the average yield per mu was 569.0 kg, which was 4.58% higher than that of the control Ⅱ.

The main points of cultivation techniques are as follows: 1. Cultivate strong seedlings: adopt the technique of dry cultivation and early development to cultivate strong seedlings with many tillers; 2, transplant: 2 thousand holes per mu, with 2 grain seedlings per hole, with specifications of 16.5x26.4cm or 13.3x33cm, basic seedlings per mu 10-120000; 3, fertilization: adequate base fertilizer, early application of seedling fertilizer, re-application of panicle fertilizer, as appropriate, special attention should be paid to the combined application of phosphorus and potassium fertilizer. 4, water management: require live barley in inch water, shallow water tillering, full seedling drying field; 5, prevention and control of diseases and insect pests: prevention and control of evil seedling disease at seedling stage.

Approval opinion: after examination, the variety conforms to the national rice variety approval standard and has been approved. This variety has moderate ripening period, high yield, medium resistance to rice blast and average rice quality. It is suitable for planting one-cropping middle rice below 800 meters above sea level in Wuling Mountain area of Hubei, Hunan, Guizhou and Chongqing.
