摘要
依据大豆品种志和选育报告（1941~2011年）登记的黑龙江省育成大豆品种的育种方法和各性状数据,应用统计学方法对所育成大豆品种的育种方法、产量、蛋白质含量、脂肪含量、结荚习性、种植密度、植株高度、百粒重、叶形、花色等性状演化进行分析。结果表明：黑龙江省大豆的育种方法以系谱法为主,呈多元化发展。系谱法育成品种占所有品种的90.4%,其余为整理单株、辐射育种、花粉管通道等方法育成。大豆品种产量呈持续增加趋势,植株增高是构成产量增加重要因素之一;叶型和结荚习性发生了定向变化,亚有限结荚习性和披针叶形品种明显增多;花色以紫花居多,紫花与白花的品种符合自然分配比例;脂肪增加明显,蛋白基本无变化。
Statistical method was used to analyze the variation and evolution of breeding method and traits of soybean in Heilongjiang province. The traits included yield,protein content,oil content,pod hearing habits,planting density,plant height,100-seed weight,leaf shape and flower color of soybean. The results showed that pedigree method still was the main method,more and more other methods were used to assistant breeding. The yield of soybean varieties presented continuous increasing in Heilongjiang,and the rising of plant height was one of the important factors to yield increasing. The average planting density had no obvious change,but the changes of the cultivation pattern made it more reasonable. The directive selection happened accidentally in long leaf and pod hearing habit soybean varieties. The flower color mostly was purple,and the varieties with purple and white flower conformed to the natural allocation proportion. Owing to the breeding objective,the fat content increased obviously whereas the protein content had no difference.
