Abstract: This study describes an investigation to test whether genotypic differences for reproductive frost tolerance in field pea (Pisum sativum L.) can be measured in the field. The method involved individually tagging flowers or young pods at particular stages of development within 48 hr after a frost event and assessing pod survival and seed damage at maturity. Four field pea varieties were grown in 2011 in an experiment which measured the loss of pods following a specific frost event. This experiment also tested the impact of trellis and pathways sown with barley on the efficacy of the frost tolerance data. In 2012, an additional genotype was also tested and, in addition to pod loss, data were collected on seed damage in surviving pods. Results from both years showed significant genotypic differences. There was also a significant positive correlation between mean variety pod loss in 2011 and 2012 indicating reliability of this method across seasons.
