| Abstract: | The cloned rice blast resistance genes,Pi9、Pib、Pi5、Pita、Pi2、Pikh、Pikm and Pigm,which showed broad-spectrum blast resistance in different rice growing regions,and had been widely used in rice breeding for blast resistance.In order to determine the distribution and resistance performance of rice blast resistance genes in japonica rice in the Yangtze River Delta,52 japonica rice germplasms were tested by using the functional markers of the above 8 disease resistance genes.At the same time,the spore mixtures of representative strains of rice blast,2019-746,2019-587,2019-924,2019-16-3,2019-522 and 2019-863 in Jiangsu province in 2019,were used to identify the resistance of the tested germplasms.The results showed that Pib and Pita,which had higher distribution frequencies of 78.85%and 50.00%respectively in the tested germplasms,and the distribution frequencies of other genes were 38.46%(Pikh),34.62%(Pi9),23.08%(Pikm),21.15%(Pi2)and 5.77%(Pi5),respectively.Pigm gene was not carried in all the tested germplasms.The results suggested that the tested germplasms with disease-resistant genes Pita,Pi5,Pi2 and Pikm showed a high proportion of disease resistance.Pita,Pi5,Pi2 and Pikm can be used as the main genes to improve rice blast resistance in future.The results of this study provide a scientific basis for the utilization of rice blast resistance genes in the Yangtze River Delta. |
