摘要
盐碱胁迫是影响作物产量与品质重要的非生物逆境胁迫之一,通过作物耐盐碱性QTL研究对辅助选择抗逆品种具有十分重要的作用。而精准表型鉴定是抗逆QTL定位能否成功的关键。本综述从鉴定试材、鉴定介质、胁迫浓度、胁迫时期、处理方法、鉴定指标以及评价体系等方面全面地总结了迄今为止作物耐盐碱QTL定位表型鉴定的研究进展,并进行了讨论,同时对未来作物耐盐碱表型鉴定技术的发展提出展望。
Salinity-alkalinity stress is one of the important abiotic stresses, which affects crop yield and quality. QTL mapping plays an important role in choosing resistant variety. Accurate phenotypic identification is the key to map QTLs successfully. This research reviewed the progress of crop phenotyping of QTL mapping associated with salinity-alkalinity tolerance so far, which included materials, medium, stress concentration, stress period, treatment, measured indicators and evaluation system, etc. In this research, the above contents were discussed. At the same time, it predicted the prospects of phenotypic characterization technique related with crop salinity- alkalinity tolerance.
