Abstract:

To carry out a theoretical research on wheat and improve the breeding effect, the design and creative thinking, the prominent characteristics and the varieties bred with ‘Lumai 14’ as parent were analyzed in this paper. From 2001 to 2018, 39 new wheat varieties were bred directly and 92 new wheat varieties were bred indirectly with ‘Lumai 14’ as parent by 89 scientific research units and breeding enterprises including Chinese Academy of Sciences, Chinese Academy of Agricultural Sciences, China Agricultural University and those in Shandong, Jiangsu, Hebei, Anhui, Henan, Shanxi, Shaanxi, Xinjiang, Guizhou and Tianjin. All the varieties were authorized 166 times in 9 provinces and 2 municipalities and obtained national authorized certification 36 times. ‘Lumai 14’, as a new generation of key parents, has contributed greatly to the wheat production and breeding in China.

Key words: wheat, key parents, ‘Lumai 14’, breeding value, whole genome, analysis, evaluation
