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

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.)

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

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.

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.
Journal ArticleDOI

Pyramiding three bacterial blight resistance genes (xa5, xa13 and Xa21) using marker-assisted selection into indica rice cultivar PR106

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.
