【Abstract】 Using the new line “Yan 1061” characterized by short stature, big spike and “Lumai 14” characterized by high and stable yield, tolerance to various diseases as the crossing parents, through coordinating the contradiction between number of kernels per spike and weight of 1000 kernels, maintaining adequate number of spikes, establishing a reasonable plant morphological model, we have successfully developed a new middle-type winter wheat variety “Yannong 23” which has the characteristics of high and stable yield, disease resistance, good yellowing, extensive adaptation and harmonious yield components.更多还原
