Abstract：Tosreenforhigh-yield，igh-qualityandwidelydaptablefloweringCinesecabbage（Brassicacmpestris L.ssp.chinensisvar.Utilis TsenetLee.）germplasm，this studyanalyzedthevariationofkeyagronomic traitsand their broad-sense heritabilityacross173flowering Chinese cabbage accessions from diverse geographical origins under six planting environments.The genotype-environment interactions were evaluated using GGE biplot analysis.The results revealed extensivevariation in eightagronomic traits within thecollcted flowering Chinesecabbage population：Plant spread，single plant mass，plant height，maximum leaf length，maximum leaf width， maximum petiole length，leafcolor， and flowering time.The coefficient of variation（ CV） ranged from 6.65% to 80.42% ，with the highest average coefficent of variation observed for single plant mass（ 80.42% ）and the lowest for floweringtime（ 6.65% .Broad-sense heritability ranged from 52.94% to 90.12% ，withmaximum leaf length（ 90.12% ）and maximum petiole length（ 89.63% ） demonstrating strong genetic determination， while plant height exhibited the lowest heritability 52.94% ），indicating its susceptibilitytoenvironmentalinfluence.Through GGEbiplotanalysis，14accessions withconsistentadaptabilityacross environmentsand 21 with stable，desirable phenotypic traits were identified.These findings provide valuable insights for selecting complementary parental lines in breeding programs aimed at developing superior flowering Chinese cabbage varieties.
