Last Updated: 2024/11/06, (2) characteristics: the combination has vigorous growth, strong tillering ability, good plant leaf type, good color conversion in the later stage, the whole growth period is about 146days, 6-7 days longer than the control Shanyou 195.The plant height is 109.4 cm, the effective panicle per mu is about 180000, the ear length is 24.0cm, the panicle is flat with 148.2 grains, the seed setting rate is 81.4%, and the 1000-grain weight is 28.

The main results are as follows: (1) Variety source: this variety is a medium indica medium maturity hybrid combination of Fu 74A male sterile line and Chuanhui 802 restorer line used by Genesis Institute of Sichuan Academy of Agricultural Sciences.

(2) characteristics: the combination has vigorous growth, strong tillering ability, good plant leaf type, good color conversion in the later stage, the whole growth period is about 146days, 6-7 days longer than the control Shanyou 195.The plant height is 109.4 cm, the effective panicle per mu is about 180000, the ear length is 24.0cm, the panicle is flat with 148.2 grains, the seed setting rate is 81.4%, and the 1000-grain weight is about 28.0g. The roughness rate is 81.55%. The milled rice rate is 70.04%, the head rice rate is 53.59%, and the rice quality is medium. The identification of resistance to rice blast: leaf temperature 5-8, neck blast 0-7, the resistance to rice blast was stronger than that of the control.

(3) yield performance: participated in the regional test of medium indica maturity group in Sichuan Province from 1995 to 1996, the average yield per mu in two years was 537.14 kg, 10.90% higher than that of the control.

(4) the main points of cultivation: the seedling age is about 45 days, planting 1.5-17000 holes per mu, basic seedlings about 100000 per mu, heavy bottom and early topdressing, pay attention to the combined application of nitrogen, phosphorus and potassium fertilizer.

(5) suitable planting area: suitable for planting Shanyou 195 and Fuyou 838.
