【摘要】 NS189系廊坊市农林科学院利用引自美国的高蛋白玉米材料AM01与国内玉米农家种‘八趟白’杂交，按预定育种目标，经多代自交定向选育而成的白粒玉米自交系。该自交系具有穗大、矮秆、秆硬、耐密植、出籽率高、结实性好、一般配合力高等特点。该自交系杂交一代具有高产、出籽率高、抗病性和适应性强的优点。作为一个创新资源，该自交系预期可在玉米高产育种、白粒玉米育种、高蛋白玉米新品种选育上具有潜在的应用价值。更多还原

【Abstract】 The NS189 is a white maize inbred line bred by Langfang Academy of Agriculture and Forestry Sciences using the high-protein maize material AM01 introduced from the United States and the domestic maize landrace ‘Batangbai’. According to the predetermined breeding goal,the white maize inbred line was selected by multi-generation selfing. The inbred line has the characteristics of large panicle,dwarf,hard stem,high density tolerance,high seed yield,good seed setting and high general combining ability. The hybrid generation of this inbred line has the advantages of high yield,high seed yield,strong disease resistance and adaptability. As an innovative resource,this inbred line is expected to have potential application value in maize high-yield breeding,white-grained maize breeding,and high-protein maize breeding.更多还原
