Development of marker-assisted introgression lines for low erucic acid and white rust resistance in Indian mustard cultivar

Characterization of Introgressive Spring Bread Wheat Lines for Stem Rust Resistance (Including Race Ug99), the Presence of Sr Genes, and Agronomically Valuable Traits

This paper presents the results of evaluating 128 introgressive spring bread wheat lines developed at the Federal Agricultural Research Center of the South-East for resistance to race Ug99 (TTKSK) of the stem rust pathogen Puccinia graminis f. sp. tritici and its biotypes under natural infection pressure at the Kenya A...

Evaluation of microsatellite markers for resistance to downy mildew in Brassica genebank collections

The results indicate that published resistance-linked markers can provide useful information for Brassica germplasm characterization, but they cannot be used as universal predictors of downy mildew resistance without further validation in defined genetic backgrounds and against individual pathogen isolates.

Marker-assisted backcross breeding to develop wheat lines with stable yellow rust resistance without yield penalties

Wheat production faces severe yield threats globally and regionally in India from rust diseases caused by Puccinia species. Genetic resistance breeding is the most sustainable approach to mitigate these losses, but traditional phenotypic selection is often constrained by environmental fluctuations and rapid pathogen ev...

QTL Mapping for Leaf Rust Resistance in a Wheat Recombinant Inbred Line Population of Liang66-S/Hengmai28

Leaf rust (LR), caused by Puccinia triticina, is a major constraint to global wheat production. Identifying quantitative trait loci (QTLs), conferring adult-plant resistance (APR), and developing breeder-friendly markers are essential for durable disease control. In this study, a recombinant inbred line (RIL) populatio...

Mapping and Evaluation of Quantitative Trait Loci for Adult-Plant Stripe Rust Resistance in the Sichuan Wheat Cultivar Chuanmai 62

Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), poses a persistent threat to wheat production in China. The Sichuan cultivar Chuanmai 62 (CM62) has exhibited stable adult-plant resistance (APR) for over a decade. To elucidate its genetic basis, we evaluated a recombinant inbred line population (CM62 ×...

Marker aided introgression of QTL hotspot carrying CaTIFY4b-H2 haplotype enhances yield and drought resilience and offers significant economic gains to Indian chickpea farmers
