盐胁迫与非胁迫条件下控制番茄苗期重要植物学性状的QTL对比研究
Comparative QTL Analysis for Phytological Traits of Tomato during Vagetative Stage under Salt Stress and Nonstress Conditions
摘要
Abstract
An advanced backcross population of 130 BC2S4 individuals was developed derived from the cross Solarium lycopersicum 9706 × Solarium 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.关键词
