Table 1 Means ± standard errors and heritabilities (h2) of the MAGIC population for agronomic and MCB resistance traits. The means of the eight parents of the MAGIC population and a control (EP42) which is susceptible to stalk tunneling are also shown

  1. TL Tunnel length, KR Kernel resistance, S Days to silking, Y Grain yield, PH Plant height. The heritabilities (h2) for each trait were estimated following [48]
  2. aThe kernel resistance was measured with a subjective visual scale of 1 to 9 in which 1 indicates completely damaged and 9 indicates no damage
