Last Updated: 2024/11/22, Characteristics: semi-winter, middle maturity, mature stage is one day later than the control stone 4185. The seedlings were semi-creeping, the tillering ability was strong, the panicle rate was low, the panicle height of main stem and tiller was different, and the panicle layer was thick. The plant height is about 80 cm, the plant type is loose and tight, the flag leaf is slightly larger, the leaf color is yellow and green, the wax is much, and the culm is thick. Spike fusiform, spikelet arranged densely, long awn, white shell, white grain, full grain, horny. The average number of panicles per mu is 388000 ears, the number of grains per spike is 36.0g, and the weight of 1000 grains is 42.9g. It is better to turn yellow. Cold resistance identification: cold resistance is moderate. Identification of disease resistance: moderate resistance

Characteristics: Semi-winter, medium maturity, maturity 1 day later than CK 4185. Seedlings are semi-creeping, tillering ability is strong, panicle rate is low, height of main stem and tillering panicle is different, panicle layer is thick. Plant height about 80 cm, plant type moderate tightness, flag leaves slightly larger, yellow green leaves, waxy, thick culms. Spikelets spindle, spikelets closely arranged, long awn, white shell, white grain, full grain, horny. The average number of ears per mu is 388,000, the number of grains per ear is 36.0, and the 1000-grain weight is 42.9 g. Yellow is better. Cold resistance identification: cold resistance medium. Identification of disease resistance: moderate resistance to leaf rust, sheath blight, high susceptibility to stripe rust, powdery mildew, stem rust. Mixed samples were measured in 2005 and 2006 respectively: Bulk density 798 g/L, 794 g/L, protein (dry basis) content 14.36%, 14.63%, wet gluten content 33.9%, 34.3%, sedimentation value 37.0 ml, 37.3 ml, water absorption 66.6%, 65.9%, stability time 3.6 minutes, 3.4 minutes, maximum extension resistance 198 E. U, 250 E. U, tensile area 50 cm2, 64 cm2.

Yield performance: In 2004~2005, the average yield per mu was 509.7 kg, which was 3.79% higher than that of control Shi 4185. In 2005~2006, the average yield per mu was 536.4 kg, which was 7.82% higher than that of control Shi 4185. The average yield per mu was 576.9 kg in 2006~2007, which was 4.64% higher than that of CK Shi 4185.

Key points of cultivation technology: suitable sowing time is early and middle October, suitable for 100,000 ~ 150,000 seedlings per mu, pay attention to stripe rust, powdery mildew and stem rust in later stage.
