Research Project: IMPROVEMENT OF PEST RESISTANCE AND QUALITY TRAITS OF SOYBEAN Project Number: 3607-21000-012-00
Project Type: Appropriated

Start Date: May 16, 2008
End Date: May 15, 2013

Objective:
1. Identify novel quantitative trait loci (QTL) for soybean cyst nematode (SCN) resistance. 2. Develop soybean germplasm with resistance to soybean aphids and map soybean aphid resistance genes. 3. Identify QTL for partial resistance of soybean to Bean pod mottle virus (BPMV). 4. Develop soybean germplasm with high seed-protein content.

Approach:
Genes involved in disease and insect resistance and other target traits will be identified through molecular mapping. Segregating mapping populations will be developed for all target traits. The genes will be tagged with DNA markers to permit incorporation into advanced soybean germplasm. Molecular markers will be identified to facilitate marker-assisted selection of enhanced germplasm. Appropriate methods and technology will be identified or developed to facilitate gene identification and mapping. Soybean germplasms with resistance or tolerance to soybean aphid and high-protein will be developed through a combination of the conventional and marker assisted plant breeding approaches. Virus identification and detection procedures will be developed, and sources of partial resistance to bean pod mottle virus will be identified by greenhouse and laboratory screenings of plant introductions.
