Comparing coleoptile length in wheat varieties locations

To measure the coleoptile lengths of 12 wheat varieties under different soil temperatures according to average soil temperature data in late March and early May at Hart.

Key messages
  • Varieties with the longest coleoptiles on average were Cutlass and Yitpi with 81 mm and 80 mm, respectively.
  • Varieties with the shortest coleoptiles on average were Cobra and Wedgetail with 61 mm and 62 mm, respectively.
  • Increasing soil temperature had a negative impact on coleoptile length with an average length of 67 mm recorded at 21°C, compared to 72 mm at 16°C.
