Abstract:

Progenies of soybeans resistant to SCN3 ×resistant to SMV1 were studied , Five treatment s for F1 toF5 were adopted under dif ferent selection pressures .The yield comparison (LSD0 .05)among these treatment sshowed in three classes A , B and C .The coef ficient of variation of yield characters wi th each selection methodw as very different .The resistant gene interaction of SCN3 and SMV1 had an additive ef fect for incresed production.The increase w as 8 -35 .9 %.The yield of the strains and quantity of polymerized resistant genes w ere positivelycorrelated , r =0 .972＊＊ .Resistant (RSVRSN)F5 plants tad apparent rate various as 0 -100 % underdifferent selection methods .RSVRSN in F5 of double inoculation or cross inoculation was 100 %, its variabilityamong plants of each st rain w as g reat .It is bet ter that to combine with of f -seasion and nusery breeding insouthern China to have an additional generation in one year .
