عنوان انگلیسی Study of morphological traits in spring wheat genotypes in related to Fusarium head blight resistant
چکیده انگلیسی مقاله Good perception of relation-sheep among plant morphological traits and resistance to fusarium head blight of wheat is quite effective to make a good success in plant breeding project. In this experiment this relation has been checked out. The morphological traits were included plant height, peduncle length and spike density. We used 28 spring wheat genotypes and 2 durum genotypes. There was significant negative correlation among plant height, peduncle length and susceptibility to fusarium head blight. In general plant tallness is an undesirable agronomic trait. In this research the biplot diagram among plant height and susceptibility index to head blight has been drown. This diagram is useful to select head blight resistant and dwarf genotypes at the same time. According to our results Frontana, Wangshoby and Frontana M.X have been selected as a most resistant genotypes to head blight, these genotypes belonged to tall plant group. Six genotypes have been selected as a resistant and had long peduncle at the same time, since long peduncle in wheat is quite important for increasing photosynthesis and grain yield, this result could be quite interesting. The biplot diagram among spike density and head blight resistance was helpful to select resistant genotypes. Since spike density is an important component to increase grain yield, this result could be useful for breeding project.
