| 摘 要： | 选用3个水稻野败胞质不育系及相应的保持系,3个恢复系及它们相应的野败胞质代换系,这些不育系、保持系同恢复系配组的18个 F_1,分别在秧苗期接种属我国7个稻瘟病生理小种群的21个菌株;在成株期接种15个白叶枯病菌株。结果表明,野败胞质较之正常胞质表现对这两种病菌感病稍轻;这种差异在多数保持系的基因型背景下达到显著水准, |

| Abstract: | The effect of cms-WA cytoplasm on the expression of leaf blast and bacterialblight was studied.21 isolates,belonging to seven representive races of P.oryzae inChina and 15 isolates of X.campestris pv.oryzae were used to inoculate the followinghybrid rice systems:3 cms-WA male-sterile lines(A-line)and their correspondingmaintainer lines(B-line),3 restorer lines(R-line)and their corresponding versionsin cms-WA cytoplasm as well as 18 hybrids with both normal and cms-WAcytoplasm.It was revealed that cms-WA cytoplasm appeared less susceptible to bothdiseases than cmf cytoplasm and shown that the differences in susceptibility to both dis-eases attained highly significant levels only in some of the A-lines and B-lines,Nocytoplasmic effects appeared in other nuclear cases,including R-lines and hybrids withcompletely restored fertility.The importance of cytoplasmic and genetic diversity in hybrid rice breeding wasalso discussed. |
| Keywords: | Cytoplasmic inheritance Male-sterile cytoplasm P.oryzae X.campestris pv.oryzae Hybrid rice Cytoplasmic diversity |
