分子标记选择水稻抗稻瘟病基因Pi40和Pib聚合体
Selecting the Pyramids of Blast Resistance Genes Pi40 and Pib in Rice Assisted by Molecular Marker
摘要
Abstract
Pyramiding resistance genes have been suggested as one of the most effective methods for preventing breakdown of major gene conferring resistance to blast within a very short period. The PCR markers of the blast re-sistence gene Pi40 and Pib were used to identify the genes in F2 plants of combination among the rice lines containing Pi40 and Pib respectively. The results indicated that all the plants containing any one gene,two genes of Pi40 and Pib showed resistane to blast,while the plants lacking the resistance gene were susceptible to blast. The tightly-linked markers of the resistance genes were powerful tools for the identification of Pi40 and Pib in breeding program. 28 plants pyramiding two genes of Pi40 and Pib were selected from 50 plants of the F2 population. They can be used as parents to breed rice for blast resistance.关键词
