Table 1 Means and their standard errors (± SE), and heritabilities (h 2) of RIL population derived from B73 × CML103 for traits related to resistance to the MCB and agronomic traits evaluated in two years. Mean comparisons of the parental inbreds are also shown

From: Identification of QTL for resistance to Mediterranean corn borer in a maize tropical line to improve temperate germplasm

  1. Heritabilities (h 2) for each trait were estimated following Holland et al. [15]
  2. aKernel, and shank resistance were scored on a subjective visual scale of 1 to 9 in which 1 indicates completely damaged and 9 indicate no damaged by the larvae
  3. bSignificantly different from zero at 0.05 probability level
