Journal ArticleDOI
Genomic selection and association mapping in rice (Oryza sativa): effect of trait genetic architecture, training population composition, marker number and statistical model on accuracy of rice genomic selection in elite, tropical rice breeding lines.
Jennifer Spindel,Hasina Begum,Deniz Akdemir,Parminder Virk,Bertrand C. Y. Collard,Edilberto D. Redoña,Gary Atlin,Jean-Luc Jannink,Jean-Luc Jannink,Susan R. McCouch +9 more
TL;DR: The results suggest that GS, informed by GWAS interpretations of genetic architecture and population structure, could become an effective tool for increasing the efficiency of rice breeding as the costs of genotyping continue to decline.
Journal ArticleDOI
Rice Resistance to Planthoppers and Leafhoppers
TL;DR: The review calls for a greater diversity of phenotyping methods to enhance the durability of resistant varieties developed using marker-aided selection and emphasizes a need to anticipate the development of virulent hopper populations in response to the field deployment of genes.
Journal ArticleDOI
Mapping QTL for heat tolerance at flowering stage in rice using SNP markers
Changrong Ye,May A. Argayoso,Edilberto D. Redoña,Sheryl N. Sierra,Marcelino A. Laza,Christine J. Dilla,Youngjun Mo,Youngjun Mo,Michael J. Thomson,Joong Hyoun Chin,Celia B. Delaviña,Genaleen Q. Diaz,Jose E. Hernandez +12 more
TL;DR: In this paper, the authors identify quantitative trait loci (QTL) controlling heat tolerance in rice, the progeny of BC1F1 and F2 populations derived from an IR64-×-N22 cross were exposed to 38/24°C for 14 days at the flowering stage, and spikelet fertility was assessed.

Current Status and Future Prospects for Research on Blast Resistance in Rice ( Oryza sativa L.)
Gurdev S. Khush,Kshirod K. Jena +1 more
TL;DR: Rice research should focus on identifying more durably resistant genes, tagging of these genes with molecular markers and pyramiding these genes or QTLs through molecular marker-aided selection for developing more durable resistant varieties.
Journal ArticleDOI
Improvement of multiple agronomic traits by a disease resistance gene via cell wall reinforcement
Ke-Ming Hu,Jianbo Cao,Jie Zhang,Fan Xia,Yinggen Ke,Haitao Zhang,Wenya Xie,Hongbo Liu,Ying Cui,Yinglong Cao,Xinli Sun,Jinghua Xiao,Xianghua Li,Qinglu Zhang,Shiping Wang +14 more
TL;DR: It is shown that Xa4, encoding a cell wall-associated kinase, improves multiple traits of agronomic importance without compromising grain yield by strengthening the cell wall via promoting cellulose synthesis and suppressing cell wall loosening.

Pyramiding of bacterial blight resistance genes in rice: marker-assisted selection using RFLP and PCR.
Ning Huang,E. R. Angeles,J. Domingo,Gerard Magpantay,Sonam Singh,G. Zhang,N. Kumaravadivel,John Bennett,Gurdev S. Khush +8 more
TL;DR: The results of the germplasm survey will be useful for the selection of parents in breeding programs aimed at transferring these bacterial blight resistance genes from one varietal background to another.

Pyramiding three bacterial blight resistance genes (xa5, xa13 and Xa21) using marker-assisted selection into indica rice cultivar PR106
S. Singh,J. S. Sidhu,Ning Huang,Yogesh Vikal,Zhikang Li,Darshan S. Brar,Harcharan Singh Dhaliwal,Gurdev S. Khush +7 more
TL;DR: Genes in combinations were found to provide high levels of resistance to the predominant Xoo isolates from the Punjab and six races of Xoo from the Philippines, and Xa21 was the most effective, followed by xa5.
Journal ArticleDOI
Green revolution: preparing for the 21st century.
TL;DR: The technological advance that led to the dramatic achievements in world food production over the last 30 years was the development of high-yielding varieties of wheat and rice that have multiple resistance to diseases and insects and thus have yield stability.
