中文摘要:以不同亲本和F1代樱桃番茄果实为材料,分别对感官品质、营养品质以及次生代谢物质总酚和类黄酮等指标进行综合分析,并对其主效成分进行遗传倾向的研究,探讨番茄果实营养特性及对杂种后代的遗传特性。结果表明,(1)F1代樱桃番茄中7261和7264的品质较优,其营养品质以及次级代谢物总酚和类黄酮的质量分数显著较高,且产量均在6 kg/m左右;(2)在杂交育种过程中可溶性蛋白、维生素C质量分数、总酚以及类黄酮均具有超高的遗传力,均达到100%以上,对后代的遗传效果明显,而单果质量、番茄红素、可溶性糖以及可滴定酸的质量分数的遗传效果较不明显;(3)后代材料7261各指标的遗传力均显著较高,且可溶性糖、可溶性蛋白、维生素C以及总酚分别出现超高亲植株,但是在后续的研究选育中仍需进一步探索其营养价值及遗传效果。

Comparison of Nutritional Characteristics and Genetic Tendency of Different Cherry Tomato Fruits
Abstract:Using different parents and F1 generations of cherry tomato fruits as materials,we analyzed comprehensively the sensory quality,nutritional quality,,econdary metabolites,total phenols and flavonoids,as well as the genetic predisposition of its main components,and then we explored tomato nutrition Characteristics and genetic effects on hybrid offspring. The results showed that 7261 and 7264 in F1 generation of cherry tomato had better quality,the nutritional quality and secondary phenol and flavonoid mass fraction were significantly higher,and the yield was about 6 kg/m; soluble protein,vitamin C mass fraction ,total phenols and flavonoids had super high heritability in the process of cross breeding,which reached more than 100% and had obvious hereditary effect on offspring,but the hereditary effect of single fruit mass,lycopene,soluble sugar and titratable acid mass fraction were not obvious;among them,the heritability of the indicators of the 7661 progeny material was significantly higher,and the soluble sugar,soluble protein,vitamin C and total phenols appeared superhigh relatives,however,in the subsequent research and selection,its nutritional value and genetic effects were still necessary to be further explored.
