摘要
玉米自交系沈137是P群玉米种质在东华北地区应用的代表系之一,在玉米育种和玉米生产上得到了广泛的应用,具有应用时间长、地区广、种类多等特点。沈137与主要种质群Lancaster、塘四平头、Reid和旅大红骨等存在较强的杂种优势,以其所组配的杂交种均表现较强的抗病性,可作为抗病群体改良和抗病育种的重要材料。
Shen137 is one of the representative inbred lines belonging to the maize P group germplasm,which is most widely utilized in maize breeding and production in northeastern and northern China. In the paper the main heterotic pattern of Shen137 is summarized,i, e. Shen137 × Reid, Shen137 × Tangsipingtou, Shen137× Ludahonggu, Shen137 × Lancaster and so on. Meanwhile,due to strong disease resistance of Shen137,it may be considered as the important sources for disease resistance breeding.
