【摘要】 利用高抗大豆孢囊线虫病（简称ＳＣＮ）的北京小黑豆、哈尔滨小黑豆等材料作抗源，配制杂交组合，成功地选育出高产稳产高抗ＳＣＮ的黄豆新品种齐黄２５（８４０３６）和黄种皮新抗源４０Ａ、４２Ａ系列品系，还选育出农艺性状优良、高抗ＳＣＮ的褐色种皮的齐茶豆１号（济３０４５）等茶豆系列品系和黑豆品种齐黑豆２号。试验表明，黄豆品种齐黄２５兼杭１、３、５号生理小种，在病区种植比高产品种鲁豆４号增产１９０．８％，在无病地种植也比鲁豆４号增产一成以上。齐茶豆１号、齐黑豆２号既可作推广品种又可作新抗源利用及大豆抗ＳＣＮ育种策略也作了初步探讨。更多还原

【Abstract】 In this study, two highly SCN resistant black soybean varieties.Bejing Xiaoheiduo and Harbin Xiaoheiduo were used as sources of resistance to make crosses, and progenies from the crosses were screened in SCN contaminated field for SCN resistance. The results indicated that linkage between genes for SCN resistance and black seed coat can be broken.A highly SCN resis tant, high yielding yellow soybean variety, Qihuang 25 (84036), and two other yellow soybean lines, 40A and 42A,which an promising SCN resistant sources ,were successfully developed. In addition, a group of brown soybean lina, represented by Qichadou 1 (Ji3045), and a black soybeau line, all with high SCN resistance and superior agronomic characters, were also developed.Tests showed that Qihuang 25 was resistnat to No.1,3 and 5 pysiological race of SCN. In SCN contaminated and uncontaminated fields, Qihuang 25 can yield 190. 8% and over 10% more respectively, than Ludou 4, awell-known high yielding variety. Qichadou 1, 2 can be both replaced as varieties and used as new SCN resistant sources. The possible use of 40A, 42A as new SCN resistant sources and the strategy of soybean breeding for SCN resistance were also discussed.更多还原
