摘要
【目的】桂林地处亚热带季风气候带,雨热同期,水果番茄成熟的季节雨水较多,导致可溶性固形质量分数偏低,且易引起成熟果实裂果。【方法】试验通过引种31份樱桃番茄品种,开展田间品种比较试验,评价不同品种在当地气候土壤条件下的生长、产量、果实品质以及裂果抗性等方面的表现,筛选出综合性状优良、可溶性固形质量分数高且耐裂果能力强的品种。【结果】分析结果显示,31个品种的14个农艺性状种间变异系数在7%~41%之间,主成分分析6个主成分特征值大于1,累积贡献率达到79.76%,代表了主要农艺性状,通过综合得分选出得分前十位的10个品种,结合可溶性固形物和耐裂性2个指标的二维分析获得5个符合预期目标的品种,均分布在聚类分析5个群组中的综合品质高的群组中,与主成分分析结果基本相符,与田间实际生长情况符,结果可靠。【结论】筛选的5个品种“GL-25”、“GL-10”、“GL-30”、“GL-24”和“GL-4”在桂林地区的适应性优于其他26个樱桃番茄品种,适宜推广种植。
[Objective]Guilin is located in the subtropical monsoon climate zone,with rain and heat in the same period.The heavey rain during the ripening period of the cherry tomatoes leads to low soluble solids content and easily cause ripe fruits to crack.[Method]In this study,31 cherry tomato varieties were introduced and a field variety comparison trial was conducted to evaluate the growth,yield,fruit quality,and fruit cracking resistance of different varieties under local climatic and soil conditions,aiming to screen out varieties with excellent comprehensive traits,high soluble solids content,and strong fruit cracking resistance.[Result]The analysis showed that the inter-varietal coefficients of variation for 14 agronomic traits among the 31 varieties ranged from 7%to 41%.Principal component analysis revealed the eigenvalues of 6 principal components were greater than 1 with the cumulative contribution rate of 79.76%,representing the main agronomic traits.Based on the comprehensive scores,the top ten varieties were selected.Combined with the two-dimensional analysis of soluble solids content and fruit cracking resistance,5 varieties meeting the expected goals were obtained,which were all distributed in the highquality group of the 5 clusters in the cluster analysis.The results were basically consistent with the principal component analysis and in line with the actual field growth situation,indicating the reliability of the results.[Conclusion]The screened 5 varieties,namely"CL-25","GL-10","CL-30","GL-24",and"GL-4",showed better adaptability than the other 26 cherry tomato varieties in Guilin and are suitable for popularization and planting.
