摘　　要：选用黑龙江省春小麦育种史上有典型代表性的8个春小麦品种:克强、克壮、克旱6、克丰2、克丰3、新克旱9、克丰4、克旱16,结合高产、超高产小麦育种目标,分析了不同春小麦品种的产量特点及源库关系.密度试验结果表明:不同年代代表性小麦品种在各自适宜的密度条件下产量是递增的.克强、克壮、克旱6号、克丰2号、克丰3号随着密度的增加倒伏率增加,适宜密度为650万株/hm2,新克旱9号随着密度的增加产量增加,但是达到一定程度后产量增加不明显,适宜密度为750万株/hm2.克丰4号,克旱16号随着密度的增加产量明显增加,适宜密度为800～900万株/hm2.粒叶比、收获指数与产量的关系表明,克强、克壮、克旱6号的粒叶比、收获指数高,但产量不高,克丰3号、克丰4号、克旱16号产量高,粒叶比、收获指数也高.表明收获指数高,产量不一定高,但产量高的品种却常常伴随着较高的收获指数.The 8 typical spring wheat varieties were selected in the Heilongjiang Province spring wheat breeding history namely： Keqiang, Kezhuang, Kehan No.6, Kefeng No. 2, Kefeng No. 3, XinkehanNo.9, Kefeng No.4 and Kehan No.16. it was based on high production and super high production breeding goal, the different varieties yield characteristic and source and sink relations were analyzed. The density experiment result indicated that the yield of the different year representative wheat varieties has increased in respective density condition. The Keqiang, Kezhuang, Kehan No.6, Kefeng No. 2, Kefeng No. 3 were lodging along with the density increasing, the suitable density is 6,500,000/hm^2, the yield of XinkehanNo.9 was increased along with density increasing, it reached the certain degree, the yield increase was not significant, the suitable density was 7,500,000/hm^2, the yield of Kefeng No.4 and Kehan No.16 were increased obviously along with the density increasing, the suitable density was 8,000,000 - 9,000,000/hm^2. relations of the ratio of grain and leaf,the harvest index and the yield indicated that the ratio of grain and leaf,the harvest index of the Keqiang, Kezhuang, Kehan No.6 were high, the yield was not good, the ratio of grain and leaf,the harvest index and yield of Kefeng No. 3, Kefeng No.4 and Kehan No.16 were high, it was indicated that the harvest index is high, yield was not necessarily high, the high-yield variety was along with the high harvest index.
