| 摘 要： | 对132份野生大豆及种间杂交创新后代进行抗灰斑病鉴定。鉴定出2级以上抗病种质70份,其中,免疫材料23份,高抗材料27份,抗病材料20份。鉴定结果表明,野生大豆的抗病性强,抗感比例明显高于种间杂交后代和栽培大豆;野生大豆与栽培大豆种间杂交后代的抗感比例低于野生大豆,而明显高于栽培大豆。经过田间生育期调查、考种分析,综合评价鉴定材料的抗病性、农艺性状、产量性状等,筛选出高产抗病品系8个,以供抗病育种利用。

| Abstract: | 132 wild soybean and inter-species hybridization innovative g eneration have appraised in the experiment. 70 disease resistant germplasms are 2 gradeor ovcr. These germplasms include 23 immunity strains,27, highly resist ant strains and 20 resistant strains. The result showed: resistant and susceptib le ratio of G.soja is higher than inter-species hybridization generation and G.max; resistant and susceptible ratio of inter-species hybridization gener ation is lower than G. soja but higher than G.ma x. By investigation of growth periods and analysis of seed test, and re - sistant, agronomic characters and yield traits of these strains were evaluated s ynthetically .8 disease-resistant strains of high yield were screened and used f or the disease-resistant breeding. |
