从品种志分析吉林省八十五年来大豆育成品种产量和品质的演变

Changes of Yield and Quality Traits of Released Soybean Cultivars during Past 85 Years in Jilin Province

根据品种志和选育报告（1923～2007年）分析了吉林省大豆育种产量品质进展。结果表明：吉林省85a间共育成323个大豆品种，随着年代推移育成品种数量逐渐增加，2000年以后育成125个大豆品种；品种区域试验的平均产量由20世纪50年代前的1549．7kg·hm^-2提升到2000年以后的2777．8kg·hm^-2，60、70、80、90年代和2000年以后，产量增幅分别达45．2％，5．2％、5．0％、4．5％、15．3％。育成含油量超过22％的品种45个，吉育89含油量达到24．61％；蛋白质禽量超过45％品种12个，吉育101蛋白含量达47．94％；不同年代育种贡献表明，2000年以后育种进展最大。

Records and breeding reports of registered soybean cuhivars from 1923 to 2007 in Jilin Province were analyzed. Total 323 soybean cultivars have been bred during the past 85 years in Jilin and the number of released cultivars has been increased along with the time. Total 125 soybean cuhivars have been bred since 2000. Average yield of regional test cuhivars increased from 1549.7 kg·hm^-2 before 1950s to 2777. 8 kg ·hm^-2 after 2000. Yield increasing respectively reached 45.2% ,5.2% ,5.0% ,4.5% and 15.3% during 1960s, 1970s, 1980s, 1990s and after 2000. Fortyfive soybean cuhivars with oil content higher than 22% were bred and oil content of Jiyu 89 reached 24.61%. Twelve soybean cultivars with protein content higher than 45% were bred and protein content of Jiyu 101 reached 47.94%. Contributions to breeding in different years showed that breeding progress had been the largest since 2000.
