摘要: 为了明确浙江省部分水稻主栽品种和中国稻瘟菌生理小种鉴别品种中稻瘟病抗性基因分布情况,本研究采用5个基于稻瘟病抗感等位基因序列设计的功能性分子标记,对40份浙江省水稻主栽品种和6份稻瘟菌鉴别品种中PitPibPii/Pi3/Pi5、PiaPi1等5个稻瘟病抗性基因进行了分子检测。结果发现,这5个抗性基因在浙江省栽培品种中分布频率不同,其中Pib基因分布最广,占63.04%;其次是Pia,占58.70%;携带Pii/Pi3/Pi5和Pit抗性基因的材料较少,分别为21.74%和10.87%。同时用2015—2017年田间采集到的141个稻瘟菌菌株检测46个水稻品种苗瘟抗性水平,结果显示,其中仅15个品种的抗性频率在70%以上,大部分品种携带其中1~2个抗性基因。聚合了多个抗性基因的品种抗性水平相对较高。

Abstract: In order to clarify the distribution of blast resistance genes in some rice cultivars and blast-resistant cultivars in Zhejiang Province, five functional molecular markers based on blast resistance allele sequences were used to detect Pit, Pib, Pii/Pi3/Pi5, Pia and Pi1 resistance genes in 40 main rice varieties in Zhejiang Province and 6 Chinese rice blast identification varieties. The results showed that the distribution frequencies of the five resistance genes were different, Pib gene was most widely distributed, accounting for 63.04%, followed by Pia, accounting for 58.70%, Pii/Pi3/Pi5 and Pit resistance genes were less, accounting for 21.74% and 10.87% respectively. At the same time, the resistance level of 46 rice varieties to Magnaporthe grisea was detected by 141 strains collected in the field from 2015 to 2017. The results showed that the resistance frequency of 15 varieties was more than 70%. Most of the varieties carried one or two resistance genes. The resistance level of varieties with multiple resistance genes was relatively higher.
