1996年利用返回式卫星搭载花生栽培种进行空间诱变处理，将新种质创新与选育新品种相结合，诱变后代经过田问单株选择、集团选择、品种比较、区域试验和生产示范等程序，选育出了高产、优质花生新品种唐花11号（K2—5），并育成两个高蛋白花生新品系K2—5—6和K2—33—9。解决了河北省花生种植品种单～老化，新品种匮乏的问题，提高花生商品市场竞争力，增加了农民收入。唐花11号于2010年12月通过鉴定，河北省成果登记号：20102814。
Tanghua 11 （K2-5）, a new peanut variety with high yield and high quality, was screened. The screening process： primarily, space mutagenesis which combined the creation of new germplasm and new varieties with recoverable satellite which picked up the peanut cultivated in 1996. Then the mutagenesis progenies were screened through field individual plant selection, group selection, varieties comparison, regional test and production demonstration, etc. Besides, two new highprotein peanuts strains, K2-5-6 and K2-33-9, were bred. It solved the problems of peanut planting varieties absence, aging and the lack of new varieties in Hebei province, and improved the peanuts commodity market competitiveness. It played a positive role in increasing income of farmers and promoted industry development. Tanghua 11 was identified in December 2010.
