Improvement of barely to BYDV by using innovative breeding strategies – Subproject 3
Project
Project code: 2814502010
Contract period: 01.07.2011
- 31.07.2015
Budget: 7,000 Euro
Purpose of research: Experimental development
It is expected that barley yellow dwarf virus (BYDV) will become increasingly important in cereal crops since with a warming climate, virus vectors as well as novel virus strains are likely to spread across northern parts of Europe.The resistance factor Ryd4Hb confers complete resistance to BYDV and possibly to its aphidic vectors. Ryd4Hb shall be transferred to German barley breeding lines and combined with resistance to barley mild mosaic virus as well as malting quality. The project aims at identifying homozygous resistant genotypes carrying Ryd4Hb, developing mapping populations with reduced H. bulbosum donor-chromosomal segments, and establishing molecular markers closley linked to resistance. Additionally, field trials will be performed to assesss yield and malting quality The project comprise the following aims: a) mapping of molecular markers on the 3HL Hordeum bulbosum segment b) development of novel markers by uisng the SuperTag Digital Gene Expression Profiling (sub-order to GenXPro GmbH), c) MAS-based identification of progenies with reduced Hb-segments d) Identification of homozygous resistant genotypes e) Determination of quality (LfL) e) Field trials (Breeders).
