Genetics and Resistance / Génétique et Résistance High-confidence genomic regions associated with leaf stripe and spot blotch resistance in barley

Detection and Heritability of Genes Conferring Resistance to Potato Pests and Viruses in Hybrid Potato Progeny (Solanum tuberosum L.)

Potato viral infections are among the main factors contributing to reduced quality of planting material and decreased tuber productivity. Currently, no reliable chemical control methods are available for plant viral diseases. Therefore, the development of potato cultivars carrying virus resistance genes remains one of...

Unlocking the potential of spring wheat genetic resources: uncovering resistance sources against leaf rust and yellow rust

The present study aimed to identify novel loci associated with yellow rust and leaf rust in a genome-wide association study using 1984 spring wheat accessions from the German Federal ex situ Genebank.

Identification of stripe rust resistance loci in Gansu wheat landraces using genome-wide association analysis

Genetics and Resistance / Génétique et Résistance Genetic mapping and marker development for the leaf rust resistance gene Lr30 in wheat ( Triticum aestivum L.)

This study generated the first linkage map of Lr30, a gene that confers resistance against leaf rust caused by Puccinia triticina Eriks, and developed Kompetitive allele-specific PCR (KASP) markers linked to Lr30 for marker-assisted breeding.

A successful stacking of multiple biotic stress resistance in rice facilitated by genes and precision breeding tools

Genetic improvement of rice for biotic stress is a major and continuous breeding objective owing to changing pest and disease scenarios. In response to climate change, an outbreak of new pathotypes and biotypes results in huge yield loss which directly impacts the economic stability and food security. The development o...

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...
