effective qualitative traits in resistance mechanisms of rice varieties to stem borer (chilo suppressalis (walker)
the use of resistant cultivars remains one of the most reliable methods to manage the pests. in this study the mechanism of resistance in 10 lines of rice for 3 kinds of resistance (antixenoses, antibioses and tolerance) was studied. the egg set of striped stem borer on the leaf of considered lines for antixenoses and larva weight mean and survival percentage of larva were evaluated for antibio...
متن کاملEvaluation of Rice Promising Lines for Resistance to Striped Stem Borer in Field Conditions
