玉米自交系是选育玉米杂交种的基础材料。它的性状和配合力大小是决定杂交优势强弱与高产稳产的重要因素。我所从六十年代初期开始,在选育目标上,除重视自交系的配合力外,并注意抗病性的选育。于1969年培育出配合力高、抗多种病害、农艺性状优良的“330”自交系。1982年获得国家发明一等奖。 “330”玉米自交系,是从一个杂种开始自交选系的,经过连续多次自交,结合进行定向选择,于1968年与一些优良自交系轮配,1969年经过杂交 Maize Inbred lines are the basic materials for breeding corn hybrids. Its traits and combining ability are important factors that determine the strength of hybridization and its high and stable yield. Since the beginning of the 1960s, I have focused on selecting breeding targets, in addition to attaching importance to the combining ability of inbred lines and paying attention to the breeding of disease resistance. In 1969 to cultivate a “330 ” inbred line with high combinability, resistance to a variety of diseases, agronomic traits. In 1982 won the first prize of national invention. “330 ” maize inbred lines, is from a hybrid began self-selection lines, after many times in succession, combined with directional selection, in 1968 with some good inbred lines, in 1969 after crossing
