- 摘要:
- 为促进番茄新品种选育,本研究对46份番茄新品种的12个农艺性状进行调查,同时对不同果形番茄的农艺性状进行了相关性分析。结果表明:大中果形与小果形在单果重与横径、单果重与果肉厚方面呈正相关。大中果形与小果形在其他性状方面相关性表现不同。大中果形番茄单果重与横径、纵径、果肉厚、心室数呈正相关,与果形指数、可溶性固形物、坐果数呈负相关;硬度与纵径和果肉厚呈极显著正相关;可溶性固形物含量与株高和节间长呈正相关,与果肉厚、纵径、单果重、横径、茎粗呈负相关。小果形番茄在果形指数、果实硬度、可溶性固形物和坐果数方面均与其他性状相关关系不显著。
- Abstract:
- In this study,12 agronomic traits of 46 new types of tomatoes were investigated and the correlation analysis of agronomic traits of tomatoes with different fruit shapes was conducted in order to promote the breeding of new tomato types.The result showed that the single weight of different size of tomatoes(big,medium and small) was positive correlated with the transverse diameter and the sarcocarp thickness.The single weight of big and medium tomatoes was positive correlated with the transverse diameter,the longitudinal diameter,the sarcocarp thickness,and the number of ventricles were negative correlated with the index of the fruit shape,the dissolubility solid and the fruit number.The sarcocarp hardness had the significant positive correlation with the longitudinal diameter and the sarcocarp thickness.The dissolubility solid had the positive correlation at surface with the plant height and the plant joint length,it also had the negative correlation in the aspects of the sarcocarp thickness,the longitudinal diameter,the single weight,the transverse diameter and the wide of caudex.The sarcocarp thickness,the dissolubility solid and the fruit number of small tomatoes were not correlated with the other characters.
