  1. (BRANCHES) Number of branches per plant. [int] Number of branches per plant. When grown from seed, branching is initially opposite, transitioning to alternate as the plant matures. Plants propagated from cuttings generally have alternate branching in the whole plant Stack et al. (2021). Modified Carlson et al. (2021).

  17. (TRK_RATIO) Test phenotype calculated as the ratio of trunk length divided by the height of the plant [TRKL/HT]. This is a proxy for the degree of branching on the lower portion of the plant, which has been identified in conversations as an important agronomic trait for fiber production. PGRU is evaluating this trait, but it is not currently included in the Hemp Phenotyping Handbook.
  18. (TRKL) Trunk length. [decimal; cm] Trunk length (trkl) is evaluated as distance from ground to first branch. See Carlson et al. (2021).
