对我国常用的9个恢复系和7个不育系所配组的13个杂交稻组合的P_1,P_2,F_1,F_2和B_1F_15个世代抗水稻细菌性条斑病的遗传规律进行分析,结果表明7个不育系均不含抗病基因,恢复系测49和测64含两对主效基因,密阳46和秀5含1对主效基因,辐26,2374,102,桂33和594不含抗病基因。抗病对感病为显性。
Genetic traits of P 1, P 2, F 1, F 2 and B 1F 15 resistant rice bacterial leaf streaks in 13 hybrid rice combinations, which are commonly used in 9 restorer lines and 7 inbred lines in China, were analyzed. The results showed that All 7 CMS lines did not contain disease resistance genes, and restore lines 49 and 64 contained two pairs of major genes. Miryang 46 and Xi 5 contained one pair of major genes, and the spokes were 26,2374,102, Guangxi 33 and 594 Free of disease resistance genes. Resistant to the disease is dominant.
