MNP (multiple nucleotide polymorphism, MNP) is a new molecular marker technology emerged with the development of molecular marker technology. While genotyping by target sequencing (GBTS) amplifies only one SNP site in one amplicon, MNP can amplify multiple SNP sites simultaneously in one amplicon based on GBTS. This technology has the features of low cost, high detection efficiency, flexible application and wide adaptability, Compared with SNP, MNP has better ability to differentiate varieties. In order to establish a rapid, accurate and efficient method for cassava variety identification and to screen MNP molecular markers suitable for cassava variety identification, this study screened highly polymorphic regions and designed primers in the whole genome range, and finally obtained 623 cassava MNP marker loci in the whole genome range, the cassava MNP markers were evaluated using 28 cassava varieties. The results showed that the MNP marker typing reproducibility was up to 100%. 4.07±1.68 alleles were detected in 28 cassava varieties, with a maximum of 12 alleles. When all cassava varieties were compared one by a one, 99.47%(376/378) of the differences between pairs were greater than 46%, with the proportion ranging from 0.3% to 81.0%, with a mean value of 71.78%. Meanwhile, MNP markers can be used for identification in the breeding process. In conclusion, the cassava MNP molecular markers developed in this study have high reproducibility, polymorphism and variety differentiation ability, and could be widely used for research on germplasm diversity, new variety breeding and variety identification of cassava.

MNP(multiple nucleotide polymorphism, MNP)是随着分子标记技术的发展而产生的一种新型分子标记技术。靶向测序基因型技术(genotyping by target sequencing, GBTS)在一个扩增子内仅扩增一个SNP位点,MNP基于GBTS可在一个扩增子内同时扩增多个SNP位点。该技术具有成本低、检测效率高、应用灵活、适应性广等特点,MNP标记可用于育种过程的鉴定。为了建立快速、精准、高效的木薯品种鉴定方法,筛选适用于木薯品种鉴定的MNP分子标记,本研究在全基因组范围内筛选高多态性区域并设计引物,最终在全基因范围内获得623个木薯MNP标记位点,并利用28个木薯品种对木薯MNP标记进行评价。结果表明,MNP标记分型重现性高达100%。MNP标记位点在28个木薯品种中检出(4.07±1.68)种等位基因型,最多具有12种等位基因型。对所有木薯品种进行两两比较时,99.47%(376/378)的品种对间的差异大于46%,比例在0.3%~81.0%之间,均值为71.78%。相较于SNP,MNP具有更好的品种区分能力。综上所述,本研究所开发的木薯MNP分子标记具有较高的重现性、多态性和品种区分能力,可广泛用于木薯的种质资源多样性、新品种培育及品种鉴定等研究。

MNP(multiple nucleotide polymorphism, MNP)是随着分子标记技术的发展而产生的一种新型分子标记技术。靶向测序基因型技术(genotyping by target sequencing, GBTS)在一个扩增子内仅扩增一个SNP位点,MNP基于GBTS可在一个扩增子内同时扩增多个SNP位点。该技术具有成本低、检测效率高、应用灵活、适应性广等特点,MNP标记可用于育种过程的鉴定。为了建立快速、精准、高效的木薯品种鉴定方法,筛选适用于木薯品种鉴定的MNP分子标记,本研究在全基因组范围内筛选高多态性区域并设计引物,最终在全基因范围内获得623个木薯MNP标记位点,并利用28个木薯品种对木薯MNP标记进行评价。结果表明,MNP标记分型重现性高达100%。MNP标记位点在28个木薯品种中检出(4.07±1.68)种等位基因型,最多具有12种等位基因型。对所有木薯品种进行两两比较时,99.47%(376/378)的品种对间的差异大于46%,比例在0.3%~81.0%之间,均值为71.78%。相较于SNP,MNP具有更好的品种区分能力。综上所述,本研究所开发的木薯MNP分子标记具有较高的重现性、多态性和品种区分能力,可广泛用于木薯的种质资源多样性、新品种培育及品种鉴定等研究。

MNP (multiple nucleotide polymorphism, MNP) is a new molecular marker technology emerged with the development of molecular marker technology. While genotyping by target sequencing (GBTS) amplifies only one SNP site in one amplicon, MNP can amplify multiple SNP sites simultaneously in one amplicon based on GBTS. This technology has the features of low cost, high detection efficiency, flexible application and wide adaptability, Compared with SNP, MNP has better ability to differentiate varieties. In order to establish a rapid, accurate and efficient method for cassava variety identification and to screen MNP molecular markers suitable for cassava variety identification, this study screened highly polymorphic regions and designed primers in the whole genome range, and finally obtained 623 cassava MNP marker loci in the whole genome range, the cassava MNP markers were evaluated using 28 cassava varieties. The results showed that the MNP marker typing reproducibility was up to 100%. 4.07±1.68 alleles were detected in 28 cassava varieties, with a maximum of 12 alleles. When all cassava varieties were compared one by a one, 99.47%(376/378) of the differences between pairs were greater than 46%, with the proportion ranging from 0.3% to 81.0%, with a mean value of 71.78%. Meanwhile, MNP markers can be used for identification in the breeding process. In conclusion, the cassava MNP molecular markers developed in this study have high reproducibility, polymorphism and variety differentiation ability, and could be widely used for research on germplasm diversity, new variety breeding and variety identification of cassava.
