用SSR分子标记RM316对黑龙江省45个水稻主栽品种(系)的抗稻瘟病基因Pi15(t)进行检测。结果表明,检测到45个水稻主栽品种(系)有30个水稻品种(系)含有Pi15(t)抗瘟基因,明确了该基因在黑龙江省水稻主栽品种(系)中的分布情况,为抗稻瘟病品种的选育和利用提供了理论依据。
The rice blast resistance gene Pi15 (t) of 45 rice cultivars (lines) in Heilongjiang Province was detected by SSR molecular marker RM316. The results showed that 30 rice cultivars (lines) from 45 rice cultivars (lines) were found to contain the Pi15 (t) resistance gene and the distribution of the gene in rice cultivars (lines) in Heilongjiang Province was determined. This provided theoretical basis for the breeding and utilization of rice varieties resistant to blast disease.
