Abstract: A doubled haploid(DH)population derived from broccoli combination of inbred lines 86101 and 90196 was used to investigate the inheritance of sulforaphane content in broccoli(Brassica oleracea L. var. italica Planch.)florets by high performance liquid chromatography(HPLC)and mixed major gene plus polygene inheritance model. The population consists of 176 DH lines was obtained by F1 microspore culture,and the trial was set by random complete block design with three replications. The optimal model was three major genes plus polygenes. The heritability of major genes and polygenes was 89.28% and 2.58% individually which showed major genes had a key role in controlling sulforaphane content. At the same time,major genes followed addictive effect and epistatic effect.

Key words: broccoli, DH population, sulforaphane, genetic analysis, high performance liquid chromatography(HPLC)
