【正文】 and 901 primer pairs produced clear PCR products. Result The posite linkage maps consist of 22 posite linkage groups (LG) with 175 SSR markers (including 47 SSRs on the published AA genome maps), representing the 20 chromosomes of A. hypogaea. The total posite map length is cM, with an average marker density of cM. Experiment Purpose The objective of this study was to develop a parative integrated map from two cultivated cultivated rebinant inbred line (RIL) mapping populations and to apply in mapping Tomato spotted wilt virus (TSWV) resistance trait in peanut. Result A total of 4,576 simple sequence repeat (SSR) markers were used for screening polymorphisms. A total of 324 markers were anchored on this integrated map covering 1, cM with 21 linkage groups (LGs). 分子標記的應用前景 通過分子標記技術研究花生種質資源的 DNA 分子多態(tài)性 ,從分子水平上揭示花生種質資源的遺傳變異 ,篩選出適合花生種質資源指紋圖譜鑒定的分子標記技術 , 找出不同花生種質資源間的分子標記 ,直接為花生品種改良和種質資源的鑒定、保存提供可靠的遺傳標記和新技術新方法 ,為下一步研究各種遺傳標記的遺傳連鎖關系、分子標記輔助育種、遺傳圖譜構建、數(shù)量基因座定位及基因克隆打基礎 ,對花生染色體組結構和功能基因組研究等方面也有重要意義。 謝 謝
