In order to improve bread- and noodle-making qualities of winter wheat cultivars in China, breeding of new strong-gluten wheat germplasm with high-yield and good-quality characteristics is absolutely necessary. Initiated by introducing Lancota as one of the parent materials, stronggluten wheat line Lu 884187 showing good bread-making quality and high-yield characteristics was subsequently selected. With this newly obtained wheat line as bridge parent, Jimai 20, a new strong-gluten wheat variety with good bread- and noodle-making qualities, was finally developed from the cross between Lumai 14 and Lu 884187 through pedigree method by Crop Research Institute of Shandong Academy of Agricultural Sciences and Institute of Crop Sciences of Chinese Academy of Agricultural Sciences. It was approved by the National Crop Variety Approval Committee (2004), and the Crop Variety Approval Committee of Shandong (2003), Tianjin (2004), Henan (2006), and Anhui (2006), China, respectively, Jimai 20 was put on the national protection list of new varieties of plants in 2004. Jimai 20 shows perfect combination of several good breeding characters such as high yield, wide adaptability and good resistance to winter conditions, drought, lodging and pre-harvest sprouting, high protein content, high gluten strength, good starch properties, low polyphenol oxidase (PPO) activity, and high N and P utilization ratio. In 2006, identification of disease resistance traits for 260 Chinese wheat varieties was carried out by CIMMYT, and results showed that Jimai 20 was the only variety with high resistance to Ug99 stem rust strains among all the tested varieties. Molecular markers analysis revealed that Jimai 20 had a general constitution of HMW-GS and LMW-GS: 1, 13 + 6, 4 + 12, and Glu-A3d, Glu-B3b, Glu-D3b, respectively. Results also indicated a mutation of Pinb gene (Pina-D1a/Pinb-D1b), which was responsible to grain hardness. Jimai 20 has an average yield of 7 695 kg ha-1, which is 8.7% higher than the reference cultivar Lumai 14 in a provincial yield trial in Shandong. The highest yield for Jimai 20 was 9 930 kg ha-1 achieved in an area of 0.12 ha in 2009, which set a new record for strong-gluten wheat in China. The cumulative planting area for Jimai 20 between 2002 and 2008 in Shandong, Hebei, Tianjin, Henan, Jiangsu, Anhui, Shanxi, and Hubei totaled 5.65 million ha, corresponding to an economic benefit of 6.93 billion RMB yuan in total. Additionally, 23 papers concerning Jimai 20 have been published in several scientific journals. This program was funded by the National Key Technologies R&D Program of China during the 9th FiveYear Plan Period, Agricultural Seed Projects of Shandong Province and the National High-Tech Research and Development Program of Bread and noodle quality characteristic of Jimai 20 China. These scientific achievements won the 1st prize of 2008 Science and Technology Advancem e n t Aw a r d s o f Shandong Province Jimai 20 and the 2nd prize of 2009 National Science and Technology Advancement Awards of China.
