新疆水稻主要育成品种13个稻瘟病的抗性基因分布
Distribution of 13 Rice Blast Resistance Genes from Bred Varieties in Xinjiang
摘要
Abstract
[Objective] To make clear the distribution situation of rice blast resistance genes from the main bred rice varieties in Xinjiang and provide the basis for rice blast resistance breeding.[Method] In this study,31 Xinjiang bred rice varieties were taken as materials,specific molecular markers of 13 rice blast resistance genes were used to carry out PCR identification,thus preliminarily establishing the distribution situation of resistance genes from Xinjiang main bred varieties.[Result] There were no Pi21 genes in all the test materials;The proportion of Pi9,Pita,Pib and Pikm were less,which belong to broad spectrum resistance genes,accounting for 9.68％,22.58％,6.45％ and 12.90％,respectively.However,Pi2,Pigm,Pil,Pikh/Pi54 and Pi63 that belong to broad spectrum resistance genes and Pia,Pid2,Pid3/Pi25 that belong to physiological races specific resistance genes,all existed widely between 67.74％ and 100％.The number of blast resistance genes in different varieties were between 5 and 11.Xindao 23 contained 11 blast resistance genes that polymerized all blast resistance genes except for Pi21 and Pid2.[Conclusion] Pi2,Pigm,Pil,Pikh/Pi54 and Pi63 that belong to broad spectrum blast resistance genes and Pia,Pid2 and Pid3/Pi25 that belong to physiological races specific resistance genes were widely spread in partial bred rice varieties in Xinjiang.The presence and distribution situation of blast resistance genes in varieties can be identified rapidly and efficiently by using specific molecular markers.关键词
