摘要:

【目的】 利用含有高可溶性固形物含量位点的渐渗系,探明其遗传效应及不同位点间的互作效应,为高品质番茄的遗传改良、基因聚合育种及杂种优势预测提供材料和理论支持。【方法】 选取潘那利番茄LA0716和多毛番茄LA1777渐渗群体中9个高可溶性固形物含量近等基因系为试材,通过不完全双列杂交方式获得单杂合与双杂合材料,对其可溶性固形物含量、单果重量和产量等的遗传和互作效应进行系统研究。【结果】 遗传效应分析表明,IL7-3所含有的高固形物含量位点多呈显性效应,但同时降低产量的连锁累赘位点也呈显性效应;IL9-2-5所含的高固形物含量位点具有较好的显性效应,且不降低单果重量和产量;IL1-4所含的增加果实产量的QTL呈超显性效应;IL2-6所含的降低单果重量的连锁累赘位点为显性效应。互作效应分析筛选到一系列能够显著影响固形物含量和产量的ILs或位点。其中,IL7-3和IL9-2-5所含的高固形物含量位点具有较好的上位性效应和累加效应,均能显著增加其互作组合的固形物含量,但IL7-3降低产量的连锁累赘影响了其互作组合的产量;IL2-6则能显著降低其互作组合的单果重量;IL5-4-5-44与IL7-5-5能够分别增加其互作组合的单株产量;在染色体上等位的IL1-4和LA3914具有较好的杂种优势效应,能够提高单株产量和园艺产量。园艺产量(可溶性固形物含量与产量的乘积)与单株产量的相关性最高,相关性系数为0.916,说明在固形物含量的遗传改良中需要兼顾产量。【结论】 番茄高固形物含量位点的聚合能够在一定程度上提高固形物含量和园艺产量,特别是遗传或生理上具有协同作用的位点互作,能够更加有效提高其互作效应。因此,选择适宜的高固形物含量位点进行聚合育种,是番茄可溶性固形物含量和产量遗传改良的有效途径。

Abstract:

【Objective】 This study aimed to explore the genetic effects and the interaction effects by utilizing the introgression lines with high soluble solid content sites, which could provide material and theoretical basis for genetic improvement of high-quality, gene pyramiding, and hybrid vigor prediction of tomatoes. 【Method】 Nine introgression lines (ILs) comprising high-SSC loci of S. pennellii LA0716 (IL1-4, IL2-6, IL4-4, IL5-4-5-44, IL7-3, IL7-5-5, IL8-3, IL9-2-5) and S. habrochaites LA1777 (LA3914) were selected to analyze the effects of genetic, intra-specific, and inter-specific interactions of soluble solids content, fruit weight, and plant yield. 【Result】 As the genetic effects, the high soluble solids loci contained in IL7-3 exhibit dominant effect, while the linkage drag of yield reducing show dominant effect. The high soluble solids loci in IL 9-2-5 exhibit dominant effect also, with the fruit weight and yield do not reduce. The yield increase loci in IL1-4 were over-dominant. The linkage drag loci responsible for reducing fruit weight in IL2-6 were dominant. In the interaction, some ILs or loci that can affect SSC and yield were selected. Such as, IL7-3 and IL9-2-5 have good epistatic and additive effects, both of which can significantly increase SSC in double hybrids, but the yield of double hybrids which contained IL7-3 was also reduced. IL2-6 can reduce the fruit weight of its interaction combination significantly. The yield of double hybrids which has IL5-4-5-44 or IL7-5-5 get increased. The alleles of IL1-4 and LA3914 both have better dominant or super-dominant effects on plant yield and horticultural yield. Our results showed that, the correlation between horticultural yield and plant yield was found to be high (with a correlation coefficient of 0.916). Thus, increasing SSC as part of genetic improvement must be performed under the premise of ensuring high yield.【Conclusion】 The total soluble solid content and horticultural yield could be improved effectively through pyramiding high soluble solids loci. In order to improve their interaction effects more effectively, the interaction of high soluble solids loci which has synergism in genetics and physiology could be better. Therefore, selecting suitable high solid content sites for multigene polymerization breeding is an effective way to improve the soluble solid content and yield of tomatoes.
