摘 要: | 1975~1995年21年间吉林省大豆主推品种共29个,分为中-中晚、中早、早熟和有限型品种4组。研究分析了它们的相互演替及遗传关系,并对今后的育种策略提出意见。中-中晚熟组中,形成了吉林3和吉林4→吉林18和吉林20→长农5和吉林27的主流遗传系统,还有九农9→丰交7607、吉林3→长农2、小金黄1号→吉林8、群选1等非主流系统。两类系统中,存在逐渐衰退现象,即后一品种较前一品种的推广表现差。在中早熟组中没有明显的主流系统。在早熟组中存在着丰收10→合丰23→合丰25主流系统,绥农4和吉林26也都岂有丰收号大豆的血缘。有限型品种组存在着早丰1→开育8、通农3→通农5、6→通农9、10两个主流系统。主推品种的血缘组成上,吉林18、吉林20、长农4等已有1/4的外来种质,吉林21、吉林27、丰交7607均含有多于1/4的外来种质,而长农5只有1/8的外来种质。含有1/4的外来种质的品种具有更大的推广优势。在育种中应制定一个既能保持外来种质占1/4,又能保证适应性品种的种质更加复杂、优良的杂交方案。

Abstract: | There were 29 major commerce soybean cultivars in Jilin province during 1975 ~ 1995.The cultivars may be devided into four groups: middle and middle - late, middle - early, early and determinante.The relations of replacement and genetic were analysed for the cultivars in each of four groups. In middle and middle-late group, main genetic systemcomposed by Jilin 3 and Jilin 4- Jilin 8 and Jilin 20 - Changnong 5 and Jilin 27 was developed . There were four minor genetic systems : Jiunong9- Fengjiao7607,Jilin3-Changnong ,Xaojinhuang 1-Jilin 8, Qunxuan 1. In main and mi- nor system , decline phenomenon existed that production area of later period variety was less than that of early period variety.In middle -early group, there was no obvious main -system. Inearly group, there was Fengshou 10-Hefeng 23-Hefeng 25 main system, Shuinong 4 and Jilin 26also had blood relationship of Fengshou 6. In determinante group, there were two main system of Zhaofeng 1- kaiyu 8 and Tongnong 3- Tongnong 5, tongnong 6- Tongnong 9, Tongnong 10.Jilin 18, Jilin20,Chagnong 4 had 1/4 introduction germplasm in blood relationship composition. Jilin 21, Jilin 27,Fengjiao 7607 had more than1/4 introduction germplasm.Changong 5 only had 1/8 introduction germplasm.The cultivars that included 1/4 introduction germplasm possessde larger planting area. Soy- bean breeding program that on the basis of possessing 1/4 in troduction germplasm,suitable germplasm which was more complex and better should be work out. |
