Collaborative project: A transcriptome-based approach for developing breeding lines in Lolium sp. with multiple pathogen resistance - Subproject 2 (LoMaRe)
Project
Project code: 2814IP007
Contract period: 01.03.2015
- 31.05.2018
Budget: 137,519 Euro
Purpose of research: Experimental development
Ryegrass (Lolium sp.) is the most important cool-season forage crop in temperate regions. Severe fungal and bacterial diseases like stem rust, crown rust and bacterial wilt can considerably affect the seed production of ryegrasses. This project aims at improving multiresistant varieties of ryegrass via marker-assisted combination and pyramidisation of resistance genes. Mapping populations segregating for resistance were created and phenotyped within the project. The development of molecular markers based on novelty next-generation sequencing approaches at transcriptomic levels (massive analysis of 3’-cDNA ends). Reliable and practicable markers for stem rust resistance gene LpPg1 and crown rust resistance gene LpPc1 were developed. Those markers were recently integrated in existing breeding programmes, allow marker-assisted selection of multiple resistances and accelerate the development of ryegrasses with high level of pathogen resistance.
