Introduction of Wheat varieties Jimai 229

Jimai 229 produced an average yield of 592.14 kg per mu in 2012-14 in Shandong Province, which was 0.84% lower than that of Jimai 22. In the 2014-2015 production test of Shandong Province, the average yield per mu was 560.43 kg, which was 0.94% higher than that of the control. In 2013 and 2014, the regional test unified sampling was tested by the Grain quality Supervision, Inspection and Test Center of the Ministry of Agriculture (Taian). The average results were as follows: grain protein content 15.1%, wet gluten 31.9%, sedimentation value 42.4ml, water absorption 57.2ml/100g, stabilization time 19.5min, flour whiteness 72.7. the main quality indicators reached the standard of strong gluten special flour. It is suitable for planting and utilization in medium and high fertilizer and water plots in the whole province.

In the 2012-2014 dry land regional trial in Shandong Province, Jimai 262 had an average yield of 454.35 kg per mu in two years, 6.44% higher than that of the control Lumai 21, and an average yield of 492.97 kg per mu in the 2014-2015 dryland group production test. 4.92% higher than the control variety Lumai 21. Two-year regional test unified sampling by the Ministry of Agriculture Grain quality Supervision, Inspection and Test Center (Taian) test results average: grain protein content 15.0%, wet gluten 35.2%, sedimentation value 28.9ml, water absorption 54.9ml/100g, stability time 2.3min, flour whiteness 80.2. It is suitable for planting and utilization in dry and fertile land of the whole province.

In recent years, the wheat breeding team of crop Institute has closely followed the national food security strategy under the new situation, and adjusted the breeding objectives and ideas according to the demand for strong gluten varieties and drought resistant varieties in wheat production. More than 29 quality indexes of Jinan 229 are better than Jinan 17. The mature period is 2-3 days earlier than Jinan 22, and it is another high quality strong gluten wheat variety after Jinan 17 and Jimai 20. In the 2012-2013 dryland regional test in Shandong Province, Jimai 262 had an average yield of 462.62 kg per mu, an increase of 9.74% over the control Lumai 21. It was the dryland wheat variety with the largest increase in yield in the past decade, and was a new breakthrough in dryland wheat breeding.
