Abstract：Toprovideatheoreticalbasisforhigh-yieldandhigh-qualitycultivationofchayote，themaincultivarsof green chayote and white chayote in western Yunnan were planted with equal row spacing under two different cultivation methods：Facilitycultivationandfieldcultivation.Theagronomictraitsandyieldcharacteristicsofchayotewereinvestigated， andthemainfunctionalnutrientsofchayote vinewereanalyzed.Theresults showedthatthecomprehensiveeffects ofcultivars，cultivation methods andseasons had extremely significant effcts onthegrowthand yieldofchayote.Insummer and autumn，chayote plants exhibitedvigorous growth，increased branching，andashorter harvesting period，with the yieldofchayotevine frombothcultivarsbeingsignificantlyhigherthaninspringand winter.Underfacilitycultivation， theyieldofchayote vineforbothcultivarsacrossdifferentseasons wassignificantlyhigher than fieldcultivation，withannual total yields increasing by 34.61% and 22.33% ，respectively.Amongthe two cultivars，greenchayote demonstrated superior plant growth and yield potential compared to whitechayote.No significant diference was observed inthecontent of polysaccharides，totalphenols，andtotalflavonoidsinchayotevineamongdiferentcultivars，cultivationmethods，or seasons.However，the watercontentofchayote vine was significantly influenced byseasonalchanges，with bothcultivars showingthe highest watercontentinsummer，indicating similar eatingquality.Therefore，cultivating these two chayote cultivars inthe south subtropicalregion can enableyear-round productionand staggered market supplyofchayote vine. Theoptimal combination identified in this studyis facilitycultivationof greenchayote. Key words： Chayote（Sechium edule）; Chaylte vine; Agronomic traits; Eating quality; Adaptability
