Shenyang Agricultural University selected Qiandaijin as female parent and Shennong 8801 as male parent in 1998. It was examined and approved by Liaoning Provincial crop Variety approval Committee in 2007.

At seedling stage, the leaf color is dark green, the leaf is erect, the plant height is 95 cm, the plant type is compact, the tillering ability is medium, the main stem has 15 leaves, the semi-tight panicle type, the ear length is 17 cm, the number of grains per ear is 120, the weight of 1000 grains is 25 grams, the glume is yellow and white, and there is no awn. Determined by the rice and product quality supervision, inspection and testing center of the Ministry of Agriculture, brown rice rate is 81.6%, milled rice rate is 73.4%, head rice rate is 66.3%, grain length is 5 mm, grain length / width ratio is 1.8, chalky grain rate is 6%, chalkiness degree is 0.4%, transparency grade 1, alkali nitrate value 7, gel consistency 68 mm, amylose 16.9%, protein 7.8%, rice quality is excellent. The disease of panicle neck blast was identified and investigated in the field.

Yield performance: participated in the regional trial of rice mid-early maturity group in Liaoning Province from 2004 to 2005, increased yield at 7 points and decreased yield at 3 points, with an average yield of 537.47 kg per mu in two years, 3.74% higher than that of Tiejing 5, and participated in the production experiment of the same group in 2006. the average yield per mu was 532.3 kg, 5.31% higher than that of Shennong 315.
