Marker-Assisted Introgression of Multiple Resistance Genes Confers Broad Spectrum Resistance against Bacterial Leaf Blight and Blast Diseases in PUTRA-1 Rice Variety

Agronomy, 2019
Bacterial leaf blight caused by Xanthomonas oryzae pv oryzae (Xoo) and blast caused by Magnaporthe oryzae are major diseases responsible for significant yield loss in rice production across all rice growing regions.

Construction of high-density genetic map and QTL mapping in Nicotiana tabacum backcrossing BC4F3 population using whole-genome sequencing

Czech Journal of Genetics and Plant Breeding, 2021
Backcrossing is a powerful tool for plant breeding. The improved marker-assisted backcrossing intends to transfer targeted genes or quantitative trait loci (QTLs) of interest from a donor parent into a recurrent parent.

Selection in backcross programmes [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2005
Backcrossing is a well-known and long established breeding scheme where a characteristic is introgressed from a donor parent into the genomic background of a recurrent parent. The various uses of backcrossing in modern genetics, particularly with the help of molecular markers, are reviewed here.

Development of herbicide-tolerant irrigated rice cultivars Desenvolvimento de cultivares de arroz irrigado tolerantes a herbicida

Pesquisa Agropecuária Brasileira, 2010
The objective of this work was to develop new irrigated rice lines tolerant to imidazolinone herbicides. The backcross breeding procedure was used to transfer the imidazolinone tolerance allele from mutant 93AS3510 to the recurrent parents 'BRS 7 Taim ...

Murine models of renal disease: Possibilities and problems in studies using mutant mice [PDF]

, 2000
The elucidation of the pathogenesis of human renal disease at the molecular level has been facilitated by the growing field of gene targeting and the development of mouse strains with single-gene deletions - the `knock-out' mice. Experimental nephrology,

Introgression of Shoot Fly (Atherigona soccata L. Moench) Resistance QTLs into Elite Post-rainy Season Sorghum Varieties Using Marker Assisted Backcrossing (MABC)

Frontiers in Plant Science, 2017
Shoot fly (Atherigona soccata L. Moench) is a serious pest in sorghum production. Management of shoot fly using insecticides is expensive and environmentally un-safe.

Análise da recuperação do genitor recorrente em maracujazeiro-azedo por meio de marcadores RAPD Recovery analysis of recurrent genitor in sour passion fruit through RAPD markers

Revista Brasileira de Fruticultura, 2009
O Brasil é o maior produtor mundial de maracujá, entretanto tem-se observado redução na produtividade do maracujazeiro nos últimos anos, devido, principalmente, a fatores fitossanitários.

Genetic Similarity Between Donor And Recurrent Parents Can Reduce The Number of Backcross Generation In Marker-Assisted Backcross

Euphytica, 2021
Abstract The marker assisted backcross (MABC) method is the most used to obtain transgenic hybrid and transgenic inbred lines in maize with few backcrosses (BC) generations. It is possible that the use of donor parents with greater genetic similarity with recurrent parents can further reduce the number of BC generation to recover recurrent ...

Resistance to powdery mildew (Erysiphe polygoni) and yield on afila pea (Pisum sativum L.)

Temas Agrarios, 2015
In the past five years in the department of Nariño, the increase in severity of damage produced by oidio (Erysiphe polygoni) in vetch has been observed, which produces loss of yield crop between 20 and 40%.
