Identification of DNA markers linked to a blast resistance gene in rice



Identification of DNA markers linked to a blast resistance gene in rice



Induced mutations and molecular techniques for crop improvement Proceedings, Vienna, Austria, 19-23 June 1995: 253-261



A pair of near isogenic lines, K80R and K79S, were developed using a local Chinese indica rice cultivar, Hong-jiao-zhan, as the Pyricularia oryzae resistance donor and IR24 as the recurrent parent. Ten putatively positive markers were identified by screening 177 mapped DNA markers. Using the 143 plants of the F2 population of K80R/K79S, 3 RFLP markers (RG81, RG869 and RZ397) on chromosome 12 of rice were verified to be closely linked to the blast resistance gene.
