Management of maize stem borers through Host plant resistance

Project Title: Management of maize stem borers through Host plant resistance
Total approved cost of the project: 60.56 lakhs

Objectives:

  • Identification and validation of resistant source(s) of maize for stem borer(s) under artificial conditions
  • To investigate morphological and biochemical basis of resistance to stem borers
  • QTL Mapping of gene(s) conferring resistance to stem borer(s)
  • Development of inbreds resistance to stem borers

Major achievements

  • Two genotypes [(E13043/V373)BIO9544]-4-2-1-2 (2.5) and [(E13118/V373)BIO9544]-5-1-2-2-1 (2.5) were found promising against C. partellus.
  • Higher concentrations of cell-wall bound p-CA, ferulic acid and tannin content are the possible biochemical defence mechanisms in maize against S. inferens.
