对东乡野生稻3个生态群落株系及协青早B//协青早B/东乡野生稻的BC1F6株系进行南方水稻黑条矮缩病抗性鉴定,筛选对南方水稻黑条矮缩病抗性较好的种质资源。利用筛选到的协青早B//协青早B/东乡野生稻的抗性株系,与光温敏核不育系C47S杂交转育,鉴定筛选到6份对南方水稻黑条矮缩病抗性较好的光温敏核不育系,为选育抗南方水稻黑条矮缩病的两系杂交稻组合奠定了材料基础;同时表明,来源于东乡野生稻的对南方水稻黑条矮缩病抗性由数量性状基因控制。
Rice germplasm for the resistance to southern rice black streaked dwarf virus (SRBSDV) was screened from rice lines of three ecological populations of Dongxiang wild rice and BC1F6 lines of the cross Xieqingzao B//Xieqingzao B/Dongxiang wild rice. A resistant line identified from the BC1F6 population was crossed to photo-thermo-sensitive genic male sterile line (PTGMS) C47S. Six PTGMS lines which were resistant or moderate resistant to SRBSDV were selected.. It was also found that the SRBSDV resistance was normally distributed in the segregating populations, indicating that the resistance to SRBSDV in Dongxiang wild rice was controlled by quantitative trait loci.
