Abstract: [Objective] To study and carry out cluster analysis of the phenotypic diversity,the chlorophyll content of different parts of fruit and the soluble solids content of mature fruits of 25 tomato cultivars heirlooms and 3 wild tomato varieties.[Method] Chlorophyll of small and mid-development fruit was detected by spectrophotometry and the soluble solids was checked by using refractometer.Also,cluster analysis of the Heirlooms was carried out.[Result] 3 wild tomato and tomato heirlooms strains had obvious difference in chlorophyll and soluble solids,and through cluster analysis,it was differentiated from heirloom strain.In the Heirloom strain,the content of chlorophyll in the fruit bearing part was higher than that of the bottom parts.The content of soluble solids related to fruit quality was basically consistent with that of tomato fruit.The highest soluble solid content was 7.07;,which was found in cherry tomato:Yellow Vemissage.[Conclusion] The Bali which is regular shape has 6.76; of soluble solids and the big fruit of Big Zebra has the soluble solids of 6.13;.These species could be used f to meet the different breeding researches to improve the quality of the tomato fruit shape.

摘要： [目的]对25个栽培番茄Heirlooms和3个野生番茄品种进行田间表型多样性分析,对果实不同部位叶绿素含量和成熟果实可溶性固形物含量进行检测及聚类分析.[方法]分别在小果期和中果期利用分光光度法,检测番茄果实上部和下部叶绿素含量的差异,运用折光仪检测番茄果实3个发育时期的可溶性固形物的含量并进行聚类分析.[结果]3个野生番茄与栽培番茄Heirlooms品系在叶绿素和可溶性固形物方面具有明显的差异,并通过聚类分析与Heirloom品系区分.在Heirloom品系中,叶绿素含量在含有果肩的部分明显高于远离果肩的底部,果实品质相关的可溶性固形物的含量与番茄果实果肩部分叶绿素含量表现基本一致.可溶性固形物含量最高为7.07;的Heirloom品系中的樱桃番茄Yellow Vernissage.[结论]具有正常果型的Bali可溶性固形物含量为6.76;,以及具有6.13;可溶性固形物的大果型Big Zebra,均可以用于满足不同果形的番茄品质提高的育种研究应用.
