中文摘要：

本报告主要成果归纳为下列4个方面： 1、建立一套有效的基因聚合育种的技术。(1)开发了稻瘟病抗性基因Pi-9、白叶枯病抗性基因Xa-23、直立稻型基因Ep-1、广亲和位点Sn-5、稻褐飞虱抗性基因Bph3、bph20（t）、bph21（t）、bph22（t）、bph23（t）和两个互作感光性基因的精密或较精密的分子标记用于育种的杂交后代辅助选择。（2）建立了由简单到复杂的基因聚合程式。（3）标记辅助选择聚合2至多个抗BPH基因，提高后代的抗性水平，效果非常显著。标记辅助选择与表型（抗性等）鉴定相结合，提高育种效率和选择的准确性。 2、目标性状基因导入系培育。（1）抗稻瘟病基因导入系培育获得了包括先B、天B、盟B和特B的杂交后代在内的抗性株系25份。（2）抗稻白叶枯病导入系培育获得用于本实验的各个保持系和两系不育系的抗白叶枯病基因Xa23的回交导入系；其中先抗A和天抗A不育系通过了省级鉴定。（3）广亲和性导入系培育获得727份广亲和性较好的株系，其中获得14份个粳稻背景占比例大于30%、结实正常（76-91%）的优良恢复系株系。（4）直立穗型籼稻株型优化方面，籼稻的直立穗型改良已经取得了实质性的进展。（5）抗纹枯病导入系培育获得了84个具有较好抗性的株系，其中先B和天B的回交后代就占74个。（6）抗稻褐飞虱基因导入系是本项研究的重点。已获得了1262份含各种抗性基因的抗性株系，包括4个保持系、1个两系不育系、和十多个恢复系的抗性基因导入系。同时，注意多样化基因利用，获得聚合2-5个抗性基因、抗性水平达到高抗甚至接近免疫水平的抗性基因聚合系。6个高抗性的优良恢复系正在用于制种参加品种比较试验。（7）品质的改良方面，主要是对外观米质差的大面积主栽杂交水稻亲本龙特甫B进行改良，获得了外观品质特别是谷粒长度明显增加、垩白度明显降低的回交系材料。（8）弱感光性基因导入系培育，对7个主栽杂交水稻亲本进行感光基因导入系的培育，现已获得高世代回交系。 3、多性状基因聚合系培育。获得抗BLB和抗BPH两性状基因聚合株系47份；具有抗BPH和直立穗两性状基因的聚合株系6份；获得抗BLB、抗纹枯病和广亲和性三个性状的基因聚合株系43份；获得兼具抗稻BLB、BPH和广亲和特性的有87份，兼具抗BLB、抗BPH和抗纹枯病特性的有24份。 4、组配多目标性状的杂交水稻试种，表现良好。

英文摘要：

Study results in this report are concluded in the following 4 respects: 1. Establishment of an efficient gene pyramiding technique. (1) Fine molecular markers for blast resistance gene Pi-9, bacterial leaf blight (BLB) resistance gene Xa-23,erect panicle gene EP-1, wide compatibility (WC) gene Sn-5, brown planthopper (BPH) resistance genes Bph3、bph20（t）,bph21（t）,bph22（t）and bph23（t）and two genes interacting with each other for photosensitive for marker-assisted selection (MAS) of hybridization progenies were exploited. (2) A gene pyramiding procedure from simple to complication was established. (3) Two or more BPH resistance genes through MAS were pyramided, which enhanced resistance level of progenies with obvious effect. The breeding efficiency and selection precision were largely increased with MAS and phenotype evaluation technology together. 2. Breeding for target-trait introgression lines. (1) Breeding for blast resistance gene introgression lines. Twenty-five resistant lines from crossing progenies of Xiang B, Tian B, Meng B and Te B were achieved. (2) Breeding for BLB resistance gene introgression line. BLB resistance gene Xa-23 introgression resistant lines from various maintainers of our lab and genetic male sterile lines were achieved, among which, two CMS lines, Xiang Kang B and Tian Kang B passed the province level variety evaluation. (3) Breeding for WC introgression lines. A number of 727 WC lines were developed in which 14 restorer lines were found with more than 30% japonica rice backgrounds and 76-91% fertility. (4) Optimum of erect panicle type of indica rice. Substantive progress was achieved in improvement of erect panicle type of indica rice. (5) Breeding for sheath blight (SB) resistance introgression lines. Eighty-four better resistant lines were bred and 74 of them from Xiang B and Tian B backcross progenies. (6) Breeding for BPH resistance introgression lines. A number of 1262 resistant introgression lines with different resistance genes including 4 maintainer lines, 1 genetic male sterile line and more than 10 restorer lines were developed. Meanwhile, diverse resistance genes were used to develop high resistance to the BPH, and pyramided lines with high resistance even near to immune level were bred by cumulating 2-5 resistance genes. Six high resistance restorer lines had been used to produce hybrid seeds for regional varietal trail. (7) With respect on rice quality improvement, rice appearance quality of a maintainer line of main cultivated hybrids was improved by increasing grain length and reducing chalkiness. (8) Breeding for weak photosensitive gene introgression lines. Seven parents of main cultivated hybrids were improved by introgression of photosensitive genes, and advance generation breeding lines were developed. 3. Breeding of gene pyramided lines for multiple traits. Forty-seven BLB and BPH resistance gene pyramided lines, 6 BPH resistance and erect panicle gene pyramided lines, 43 BLB and SB resistance and WC gene pyramided lines, 87 BLB and BPH resistance and WC gene pyramided lines, and 24 BLB, BPH and SB resistance gene pyramided lines were developed, respectively. 4. New developed rice hybrids with multiple target traits were demonstrated in the field and they presented good performance.
