- 摘要:
- Glycime soja 被认为是YMV (黄化花叶病毒)和BHC (棉灯蛾)的野生抗源, 通过Glycine max 和Gl ycine soja种间杂交研究了YMV、BHC、BP(大豆细菌性斑疹病)与抗性之间的基因连锁。结果表明只有YMV 抗性与BP感病之间是连锁的(显著偏离9: 3: 3:1)。用平方根法、Product ratio法, Emerson法和极大似然法四种方法估算了这对性状之间的重组值。所有组合、四种方法的总平均重组值为29. 05% ,表明这两个基因(性状)间有着不太紧密连锁(重组值不等于图距)。这样的连锁强度应不难得到对YMV 和BP均抗的重组型。

- The estimatio n of linkag e( s) w ere studied among resi stance to YMV ( Yellow MosaicVi rus) , resista nce to BHC ( Bilar hai ry caterpillar, Spilosoma obl iqua Walker) andBP ( Bacterial pustule c. o. X . campestri s pv. gl ycines) in the interspecific crosses between Glycine max and Glycine soja , a w ild accession recog nised as a source of resi stanceto YMV and BHC in soy bean. Recombinatio n values w ere estimated by using fo ur methodsof estima tion namely square ro ot method, product ra tio method, emeson methodand maximum likelihoo d method for the character- pair resi stance to YMV and susceptibilityto BP as o nly these characters w ere show n to be linked ( devia tion f rom 9: 3: 3: 1w as fo und sig ni fica nt ) . An av erag e v alue of recombination in all the metho ds and crossesw as 29. 05 per cent indicates the moderate linkag e betw een these tw o genes(character) . Such a moderate linkage sho uld no t be any hindrance in the w ay of synthesizing a desi rable recombinant ty pe hav ing resi stance to bo th YMV and BP.
