【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(biāo)記的應(yīng)用前景 通過(guò)分子標(biāo)記技術(shù)研究花生種質(zhì)資源的 DNA 分子多態(tài)性 ,從分子水平上揭示花生種質(zhì)資源的遺傳變異 ,篩選出適合花生種質(zhì)資源指紋圖譜鑒定的分子標(biāo)記技術(shù) , 找出不同花生種質(zhì)資源間的分子標(biāo)記 ,直接為花生品種改良和種質(zhì)資源的鑒定、保存提供可靠的遺傳標(biāo)記和新技術(shù)新方法 ,為下一步研究各種遺傳標(biāo)記的遺傳連鎖關(guān)系、分子標(biāo)記輔助育種、遺傳圖譜構(gòu)建、數(shù)量基因座定位及基因克隆打基礎(chǔ) ,對(duì)花生染色體組結(jié)構(gòu)和功能基因組研究等方面也有重要意義。 謝 謝
