利用93个SSR标记对2015年江苏水稻种子市场中的355份抽检样品的真实性进行鉴定,与标准样品间存在2个及以上位点差异的占比31.55%。发现与标样不存在或仅存在1个位点差异的抽检样品,其与标样在农艺性状上不存在差异;而存在2个及以上位点差异的抽检样品中,随着差异位点数增多,差异明显增多。判定64个抽检样品的真实性存在问题,占抽样品种的18.03%。发现单独使用农业行业标准中的或之前报道的SSR标记,均不能完全鉴别江苏水稻种子市场中的假冒套牌品种,而采用2套标记整合后的93个标记则可完全鉴别。
The authenticity of 355 samples in Jiangsu rice seed market in 2015 was identified by 93 SSR markers, accounting for 31.55% of the total. There was no difference between agronomic traits and sampling samples which had no or only one locus difference with the standard samples. In the sampling samples with two or more loci differences, as the number of different loci increased , The difference is obviously increased. It was determined that there were problems in the authenticity of 64 sampling samples, accounting for 18.03% of the sampled varieties. Found that the use of SSR markers alone or previously reported in the agricultural industry standards did not fully identify the counterfeit decks in Jiangsu rice seed market and the 93 markers after integration with 2 sets of markers could be completely identified.
