KEY PRACTICE: This study found that most hybrids could be straight combined successfully with minimal harvest losses when harvested in a timely manner under reasonably average environmental conditions. When making a seed decision, balance pod shatter resistance with other selection factors including yield potential, herbicide system, days to maturity and other agronomic factors.
PROJECT TITLE, LEAD RESEARCHER: “Quantifying genetic difference in seed losses due to pod drop and pod shattering in canola,” 2011-15, Chris Holzapfel, Indian Head Agricultural Research Foundation (IHARF)

Some varieties are better suited to straight combining than others, but success largely depends on environmental factors and timeliness of harvest.
This four-year, multi-site study aimed to evaluate the resistance of various varieties to environmental pod shatter and pod drop losses. More specifically, it intended to: quantify the frequency and amount of seed losses in straight combined canola across a range of environmental conditions; determine relative resistance to pod shatter and pod drop of varieties recommended for straight combining; and evaluate the environmental seed losses from pod drop versus pod shatter.Open the PDF to read the entire research summary from the 2015 Science Issue of Canola Digest
