Collaborative project: Identification of molecular markers for BYDV-resistance in maize – Subproject 3
Project
Project code: 2814502710
Contract period: 01.04.2011
- 31.03.2014
Budget: 67,660 Euro
Purpose of research: Experimental development
Barley yellow dwarf (BYD) is an economically important virus disease in cereals. With increasing winter temperatures, the impact of BYD on maize is expected to increase. The most effective method to control the BYD virus, which is transmitted by aphids, is to breed resistant maize varieties. The results of this study indicated that a BYDV infection had negative impacts on various plant performance traits of maize. In different genetic material, we observed a high genotypic variance for traits related to BDYV resistance, which implies that an improvement of BYDV resistance by breeding is possible. The results of quantitative genetic analyses suggested independently from each other that genes contributing considerably to BYDV resistance in maize occur on the bottom of chromosome 10. The information that has been generated in the frame of this project can be used in maize breeding programs to facilitate the breeding of BYDV resistant maize varieties.
