摘要
分析不同年份审定大豆品种的产量、农艺性状、品质的变化规律，可为大豆育种提供参考。本文根据国家农作物品种审定公告，将审定品种按时间顺序，分为2000～2004、2005—2009和2010—2014年三个阶段，分析了北方春大豆审定品种的产量、品质及农艺性状进展，结果表明，北方春大豆自1999年恢复试验以来共审定90个大豆品种，其产量总体趋势一直在提升，尤其是2010年以后产量潜力增加很大，2010—2014年的平均产量达198．4kg／666．7m2，较2000—2004年增长11．8％。平均脂肪含量表现增加趋势，15年来共审定37个高脂肪品种，占审定品种总数的41．1％，多集中在2009—2014年，但是没有高蛋白品种，脂肪与蛋白质含量呈极显著负相关。株高、单株荚数随着年代的推移总体呈增高趋势，产量与株高、单株荚数和脂肪含量呈极显著正相关，相关系数分别为0．57、0．62和0．42。
Analysis of change rule for yield, agronomic and quality traits of released soybean varieties could provide reference for soybean breeding. The advance in yield, agronomic and quality traits of soybean varieties which were be- longed to three stages, i.e., 2000-2004, 2005-2009 and 2010-2014 years according to National Crop Variety Approv- al Notice were analyzed. The results showed that 90 northern soybean varieties had been released since recovery of test in 1999, their yield were increased as time went on, especially yield potential increased greatly after 2010, the av- erage yield in 2010-2014 was 198.4 kg/666.7m2, increased 11.8% over 2000-2004. In the past 15 years, thirty seven high oil varieties were certified, accounting for 41.1% of the total number of authorized variety, more concentrated in the 2009-2014. However, no high protein variety was authorized. There was a very significant negative correlation be- tween oil and protein content. Some agronomic traits such as plant height, pods number per plant showed a trend of in- crease as time went on. Correlation analysis showed that the yield was very significantly positively correlated with plant height, pods number per plant and oil content. The correlation coefficient were 0.57, 0.62 and 0.42, separately. Key words： Northern spring soybean; Yield; Quality traits; Agronomic traits; Genetic progress
