摘　　要：通过对15个高油玉米自交系生育期、植株性状、产量性状及品质性状的初步分析,结果表明,15个高油系籽粒的脂肪、蛋白质含量高于黑龙江省普通玉米自交系,其中脂肪含量极显著高于普通自交系,淀粉含量极显著低于普通玉米自交系。除BY843、BY815生育期偏晚以外,其它高油系能够适应黑龙江省种植。多数高油系的自身产量接近普通玉米自交系,可以直接利用或者作为种质资源间接利用。大部分高油系的株高、穗位偏高,需进一步改良。The growing stages,plant tralt,yield and quality characters of 15 high oil maize inbred lines were preliminary analyzed. The results showed that the fat and protein content of 15 high oil maize inbred lines were higher than normal maize inbred lines in Heilongjiang province. The starch content of high oil maize inbred lines was significantly lower than thoes of normal maize inbred lines. Except the growing stages of BY843 and BY815 were later,the others could be planted in Heilongjiang province. Yield of most high oil maize inbred lines were close to thoes of normal maize inbred lines and they could be directly or indirectly used. Plant height and ear height of most high oil maize inbred lines were much higher and needed to improve.
