Summary

Field trials were conducted for three years on an organic farm in England to assess the performance and yield variability of two synthetic sprouting broccoli populations with 4 or 8 parents respectively, along with the original landrace mother plants and a commercial F1 hybrid variety as control (Santée). In terms of total yield, Santée outperformed the other entries, but for some other traits, e.g. heading time and number of sprouts, Santée was comparable with the mean of one or more of the genetically diverse entries. Analysis of yield variability over time showed mixed results. With regard to total yield and total sprout number, variability was higher in the F1 hybrid than in the genetically diverse populations, but for other parameters such as average sprout weight and time to maturity, patterns were less clear. Using broccoli populations in commercial production will depend on acceptability of within-population variability of phenotypic traits, especially maturation time.
