本试验以12个标记基因系及其与毫梅的杂交F_1和F_2代为材料,以湖北省代表菌系江陵691为接种菌系,研究了分属于10个连锁群的14个标记基因的遗传方式及其与毫梅的抗白叶枯病新基因X_(a-i)的连锁关系。结果发现X(a-i)与第Ⅵ+Ⅸ连锁群即第2染色体的颈叶基因nl-1相互连锁。连锁值为39.1％。对毫梅在水稻育种上的利用进行了探讨。
In this study, 12 marker gene lines and their hybrid F1 and F2 generation with Mei were used as materials, and the representative strain of Jiangling 691 was inoculated in Hubei Province. The genetic patterns of 14 marker genes belonging to 10 linkage groups And its linkage with the new gene X_ (ai) of resistance to bacterial blight in The results showed that X (a-i) and the Ⅵ + Ⅸ linkage group that the second chromosome of the cervical gene nl-1 interlocking. The chain value is 39.1%. The use of rice plum in rice breeding was discussed.
