【摘要】 针对粤东北山区冬季寡照高湿的设施环境特征及樱桃番茄主栽品种单一化问题，为筛选适宜本地设施栽培的优质樱桃番茄新品种。以粤东北山区典型设施大棚为试验基地，以广东省农业科学院设施农业研究所选育的“粤科达101”“粤科达202”和“粤科达206”为试材，采用基质栽培模式，系统比较3个品种的物候期、植株生长特性、抗病性、产量及果实品质等指标。结果表明，3个樱桃番茄新品种均具有较好的综合性状，其中“粤科达101”物候期显著提前，定植至初采期较其他品种提早5～8 d,定植42 d后株高、茎粗和叶面积分别为169.13 cm、0.93 cm和1 228.96 cm~2,显著优于其他品种；“粤科达206”产量最高，为69 601.95 kg/hm~2,采收期长达113 d;“粤科达202”单果重最大为19.76 g,但耐裂性较弱。3个品种可溶性固形物含量均达8.30%以上，其中“粤科达206”糖度最高为8.70%。因此，“粤科达206”综合表现最优，其丰产性突出、采收期长且果实商品性好，推荐作为粤东北山区设施栽培主推品种；“粤科达101”可作为早熟栽培的优选品种，“粤科达202”适合短期集约化生产，需加强裂果防控技术研究。该研究为突破境外品种垄断、建立本土化栽培体系提供了技术支撑。更多还原

【Abstract】 To address the facility environmental characteristics of low light and high humidity during winter in the mountainous areas of northeastern Guangdong, as well as the monoculture issue of dominant cherry tomato varieties, this study aimed to screen high-quality new cherry tomato varieties suitable for local facility cultivation.Using typical facility greenhouses in the mountainous areas of northeastern Guangdong as the experimental base, three cherry tomato varieties: Yuekeda 101,Yuekeda 202,and Yuekeda 206(bred by the Institute of Facility Agriculture, Guangdong Academy of Agricultural Sciences),were tested under substrate cultivation.Systematic comparisons were conducted on phenological stages, plant growth traits, disease resistance, yield, and fruit quality.The results showed that all three varieties exhibited favorable comprehensive traits: Yuekeda 101 demonstrated significantly earlier phenology, with 5-8 days shorter duration from transplanting to first harvest compared to other varieties.At 42 days post-transplanting, its plant height(169.13 cm),stem diameter(0.93 cm),and leaf area(1 228.96 cm~2) significantly outperformed others.Yuekeda 206 achieved the highest yield(69 601.95 kg/hm~2) and the longest harvesting period(113 days).Yuekeda 202 produced the largest single fruit weight(19.76 g) but showed weaker crack resistance.All three varieties had soluble solids content(SSC) exceeding 8.30%,with Yuekeda 206 having the highest sugar content(8.70%).Yuekeda 206 is recommended as the primary variety for facility cultivation in northeastern Guangdong due to its high yield, extended harvest window, and superior commercial fruit quality.Yuekeda 101 is ideal for early-maturing cultivation, while Yuekeda 202 suits short-term intensive production but requires enhanced cracking prevention strategies.This study provides technical support for breaking foreign variety monopolies and establishing a localized cultivation system.更多还原
