Studies on evaluation of soybean pod borer, grapholitha glycinivorella matsumura, damage in germplasm

To evaluate the resistance to soybean pod borer, Grapholitha glycinivorella Matsumura, in soybean germplasm collection by means of conventional screening method, the resistant 30 lines and susceptible 31 lines selected preliminry among 1440 soybean germplasm were planted in different planting time with replications. Damages of soybean pod borer between resistant and susceptible group were significantly different and the damages of the lines planted on May 27 were severe than those lines planted on June 17. The pod borer damages seemed to be related with seed weight, and the most of resistant lines beared small seeds, but the susceptible lines tend to have large seeds. Grading of damage in evaluation of seed basis was recommendable for selecting resistant lines to soybean pod borer.
