摘要: 利用来源于栽培番茄9706和野生契斯曼尼番茄LA0317杂交后的130个BC2S4株系为群体,采用营养液栽培法,在盐胁迫与非胁迫环境下分别对株高、茎粗、根鲜质量、根干质量、地上鲜质量、地上干质量以及耐盐级数进行了QTL分析。盐胁迫环境中检出13个QTL:株高2个;茎粗2个;根鲜质量2个;根干质量2个;地上鲜质量3个;地上干质量2个。非盐胁迫环境中检出32个QTL:株高6个;茎粗2个;根鲜质量6个;根干质量6个;地上鲜质量6个;地上干质量6个。另外,在盐胁迫条件下利用耐盐级数定位到2个耐盐性QTL,分别位于第3,6染色体上。通过盐胁迫与非胁迫下的QTL对比研究发现,第2,3,8染色体上的QTL仅在盐胁迫条件下能检测到,第9,12染色体上的QTL仅在非盐胁迫条件下能检测到,不同性状间的QTL存在共定位现象。同时,研究获得了5个表型和QTL分析均极耐盐的育种材料,可用于番茄耐盐新品种选育。

Abstract: An advanced backcross population of 130 BC2S4 individuals was developed derived from the cross Solanum lycopersicum 9706 × Solanum cheesmanii LA0317.Six important phytological traits were investigated under salt stress and nonstress conditions,and salt survival value was also evaluated.Using MQM mapping method,a total of 45 QTL for phytological traits of tomato were detected.2 QTL for salt tolerance were mapped to chromosome 3 and 6.Through comparative QTL analysis,it was found that QTL on chromosome 2,3 and 8 could only be detected under salt treatment,while QTL on chromosome 9 and 12 could only be detected under non-salt condition.QTL co-location among different traits was common in this study.Moreover,5 families of BC2S4 were found in this paper to be salt tolerant,thus these lines could be used as good breeding germplasm.
