2019 Hyola® TD - Canola Plant Population by Seed Size Trials Summary 

  • Yield responses across the 11 trial environments varied between varieties, seed sizes and plant population targets.

  • Previous research studies - mixed outcomes relating to the effect of seed size and plant densities on grain yield

  • Seed size, yield benefit from larger canola seed was observed by Elliot et al (2008) and Brill et al (2016),

  • Harker et al (2015), Clayton et al (2009), and Lamb and Johnson (2004) did not measure a benefit of larger seed on canola yield

2019 Hyola® TD - Canola Plant Population by Seed Size Trials Summary 

Seed size can impact the percentage of plants both emerged and established to varying levels in different environments



Larger seed has been found to provide higher observed biomass accumulation and % establishment in some environments


Larger seed at lower plant populations leads to final plant maturity being delayed.

2019 Hyola® TD - Canola Plant Population by Seed Size Trials Summary 

Higher plant populations irrespective of seed size and variety genetics often showed observed earlier maturity and sometimes

decreased plant height


(G) X (E) interactions often override (M) management decisions based around seed size and population targets on the resultant

grain yields.

2020 Hyola® TD - Research Trials Project Outline 

  • Pacific Seeds will continue this important industry research by focusing the evaluation on the relationships between TT and CT hybrids vs 3 OP TT varieties (farmer prepared retained samples)


  • Evaluations of various plant populations and seed sizes across 10 Australian Environments


  • Determining any ‘potential’ grain yield and gross return $/ha value of grading OP TT varieties to larger seed sizes and planting at higher rates versus TT and CT hybrids.
