Resistance of some elite soybean (Glycine max) lines to stem fly (Melanagromyza sojae), Bihar hairy caterpillar (Spilaretia obliqua) and tobacco caterpillar (Spodoptera litura).

摘要

An experiment was conducted in India during the rainy (kharif) season of 2002-03 to evaluate 19 soyabean (G. max) lines for resistance to stem fly (M. sojae), Bihar hairy caterpillar (Spilarctia obliqua) and tobacco caterpillar (Spodoptera litura). Based on pooled data on per cent stem tunnelling by stem fly, 10 lines were found to be resistant. Three lines, i.e. MAUS 30, PK 1347 and NRC 59 were resistant to Bihar hairy caterpillar. No line was resistant to tobacco caterpillar, but 10 lines showed moderate resistance to this pest. NRC 51 and NRC 52 were highly resistant to stem fly, and moderately resistant to Bihar hairy caterpillar and tobacco caterpillar..
