8个稻瘟病抗性基因在三系杂交粳稻亲本中的分布
Distribution of 8 rice blast-resistant genes in parents of three-line hybrid keng rice
摘要
Abstract
Rice blast-resistant genes Pi2,Pi5,Pi9,Pi54,Pia,Pib,Pit and Pita were detected in 36 restoring lines and 42 sterile lines by functional molecular markers.The results indicated that those 8 rice blastresistant genes were distributed in the 78 tested lines at various frequencies.Six rice blast-resistant genes were detected in the sterile line Shen-11A containing the most rice blast-resistant genes among the 78 lines,whereas no rice blast-resistant gene was detected in the lines 8527A,Xu-1A and 016A.The genetic distance-based cluster analysis showed that those 78 lines could be divided into 5 groups.关键词
