In order to obtain the genetic information on bolting in pak-choi (Brassica campestris L. ssp. chinensis Jusl), diallel cross was conducted using 9 cultivars, and F₁, and BC₁F₁ hybrid lines were developed. Genetic analysis for bolting under three cropping patterns, spring at field, spring in polyethylene film house, and fall at field, was carried out. Genetic parameters estimated by the genetic variances showed that there are partial dominant with additive effects, and the dominant allele in spring and recessive allele in fall cropping, respectively were involved.
