查询词典 chain reaction

The CMS line 9704A, the restorer 8001 and F, population of 9704AX8001 containing 120 individual plants were used for molecular mapping of the restorer gene by bulked segregant analysis. 515 decamer primers with arbitrary sequences were chosen for polymerase chain reaction amplification. It is found that the polymorphism between the parents could be detected by 43. 8% of the primer and one RAPD marker OPL09-76I was tightly linked to the restorer gene of the restorer 8001 with the overcross value of 4.17% and genetic distance of 4. 18cM. The marker was repeatable and easy to score.
