COMPARISON OF SYNTHETIC HEXAPLOID WHEAT LINES FOR RESISTANCE TO ROOT ROT (Fusarium spp)

In the study, 58 synthetic wheat lines and 6 bread wheat varieties were used as material. Synthetic wheat lines and bread wheat varieties were investigated for resistance to root rot under field conditions. In laboratory conditions, 1 ml (1x106 spores/ml) of root collar disease was inoculated into each tube at the junction of the stem of the plant and the soil, 1 week after seed sowing. In terms of root rot, which is one of the important problems in the Thrace region, it was determined that synthetic wheat lines showed resistance properties compared to bread wheats. While bread wheat varieties widely planted in the region do not show good tolerance in terms of resistance to root collar, synthetic bread wheat genotypes ZFSN 6, HRSN 11-14, HRSN 13-17 and HRSN 14-10, HRSN 6-8, HRSN 6-2, ZFSN 8 and ZFSN 3 genotypes showed superior properties in terms of resistance to root rot.
