Yumai 49 (formerly Wenmai 6)

Unit of Education: agricultural Technology Station, Xiangyun Town, Wen County, Henan Province.

Approval: it was approved by Henan crop Variety approval Committee in 1996 and by the National crop Variety approval Committee in 2000.

Variety approval number: national examination and approval wheat 20000006.

Variety source: selected from a single mutant plant of Wen 2540.

Characteristics: semi-winter, plant height of about 80 cm. Long awn, white shell, white grain, ear spindle type, 1000-grain weight about 37 grams. Medium maturity, strong lodging resistance, susceptible to stripe rust, stem rust, powdery mildew and sheath blight, highly susceptible to leaf rust and scab. The bulk density is 779 g / L, the protein content is 16.2%, the wet gluten content is 35.6%, the sedimentation value is 41.6 ml, the water absorption rate is 56.88%, and the stable time is 5.8 minutes. In 1997, the average yield per mu was 465.2 kg, which was 1.58% lower than that of Yumai 21 in the national regional trial of winter water group in the south of Huang-Huai River. In 1998, he participated in the regional trial of winter water group in the south of Huang-Huai River, in which there were 19 pilot projects, in which 15 points increased production and decreased yield at 4 points. the average yield per mu is 353.3 kg, which is 6.97% higher than that of the control. The experiment continued in 1999, and 15 pilot projects were conducted, of which 13 increased production and 2 reduced yield, with an average yield of 452.2 kg per mu, an increase of 9.68 per cent over the control. The average yield per mu in the past three years was 423.6 kg, an increase of 5.02% over the control. In 1999, production tests were carried out at five sites in Henan and Anhui, with an average yield of 461.7 kg per mu, an increase of 10.84% over the control.

Cultivation key points: the suitable sowing date is IO month 3-13. Apply sufficient base fertilizer, enough moisture to sow, precision sowing, sowing rate of about 5 kg / mu, high water and fertilizer can be appropriately reduced, re-application of technical fertilizer. Prevention and control of diseases, pests and weeds. Due to poor moisture tolerance, scab and leaf rust should be controlled in time.

Suitable range: Jiangsu, Henan, Anhui and Shaanxi provinces in the south of Huang-Huai winter wheat region have a yield of 450 Mu, high water and fertilizer early stubble land of 550 kg.
