Abstract: In order to provide a reference for the popularization and application of‘Ningmai 23’and for the future breeding of wheat varieties, the background and breeding process of the national authorized wheat ‘Ningmai 23’was expounded. Meanwhile, wheat ecological conditions and characteristics of this region were revealed. The results of the wheat preliminary experiment, regional test and production test were analyzed, all of the data was from the national winter wheat test of the middle and lower reaches of the Yangtze River Region for four consecutive years (from 2009 to 2013). Meanwhile, it was compared and contrasted to the control variety‘Yangmai 158’. The results showed that‘Ningmai 23’had higher and stable yield, the average yield increase 2.90% to 9.51% than that of the control variety‘Yangmai 158’, and the increased yield points were 71%-100%. The variety of‘Ningmai 23’had moderate spike numbers, larger panicle types and more kernels per wheatears and higher 1000 seed weight. Three factors of yield were coordination.‘Ning-mai 23’had an early maturation and middle resistance to scab and wheat sharp eyespot, as well as high resistance to yellow mosaic. The grain commodity was well too. In addition, in this paper the inadequacy of‘Ningmai 23’was pointed out and discussed the weaknesses of its utilization strategy. The‘Ningmai 23’was suitable cultivation for the areas of south Jiangsu and Anhui Province, and the middle to northern of Hubei Province as well as the region of Xinyang and the middle to northern part of the area in the late maturing rice rotation region.
