  团队研究方向: 

  利用优良品种背景的抗旱、耐盐、抗病、耐低氮及氮高效利用等目标性状导入系和重测序种质资源,结合高通量SNP基因型,定位和挖掘绿色性状优异基因,创建基于导入系表型和目标性状基因型的多个复杂性状分子设计聚合育种的技术体系。建立籼稻恢复系与骨干不育系的杂种优势全基因组选择预测模型;研究水稻优异种质资源的演变规律,探索建立预测和筛选未来骨干亲本和主栽品种的方法和技术;应用全基因组选择技术结合常规育种技术选育绿色超级稻新品种。

  In combination with high throughput SNP genotypes, trait-specific introgression lines (ILs) of drought tolerance, salt tolerance, disease resistance, low nitrogen tolerance and nitrogen use efficiency and re-sequencing germplasms were used to map and mine the favorable genes of green traits, create molecular designing and pyramiding breeding technical system of multiple complex traits based on phenotype of the ILs and genotype of the target trait. Heterosis and the whole genome selection of prediction model were established by Xian restorer lines and backbone sterile lines. Research the evolution of rice germplasms, exploring predicting and screening methods and techniques for future key parents and main varieties, and develop green super rice through the whole genome selection combined with conventional breeding techniques.

  

  研究进展:

  1)利用自主选育的光温敏两系不育系春6S,选育出春两优534、春两优华占、春两优121、春两优粤禾丝苗等一系列苗头新组合。2018年完成春两优534和春两优华的全部试验程序,拟2019年申报国家审定。

  2)实现春6S的技术转让(转让费600万元),未来10年与种业公司合作开展基于春6S选育杂交水稻新品种(科研经费400万元),转让和合作研发费用1000万元。

  1) A series of new hybrid rice varieties were developed using the photo-thermo sensitive male nuclear sterile line Chun 6S with our intellectual property right, including Chunliangyou 534, Chunliangyouhuazhan, Chunliangyou 121 and Chunliangyouyuehesimiao. All related experiments have been finished for Chunliangyou 534, Chunliangyouhuazhan in 2018 and will be officially approved by the State in 2019.

  2) A technology transfer of Chun 6S was realized for 6 million Chinese yuan, and collaborative breeding will proceed with a seed company to breed new hybrid rice based on Chun 6S and another research financial support of 4 million Chinese yuan, thus amounting total of 10 million for R & D activities.
