| The ergot fungus requiers a rather long time for the incubation period for a disease and fungus tends to obstract the formation of the seeds. In order to do an experiment inoculated, a spore of ergot fungi into the florets was done 2-3 days before flowering. As a result, each trisomic types recognized the infection rate to be 90% to 100% so the trisomies of complete immunity was non existent in durum wheat, Triticum durum var. hordeiforme. However, the growth rate of large sclerotium than seeds differed mutually with each trisomic types. This tend to be sensitivity on the trisomies which has been the extra chromosomes of 2A, 4A and 7B in comparison with normal plant but the trisomies related to Tri-6A line was not forming the sclerotium of large size than seeds and grew outside the florets. Consequently, the resisitant gene against ergot fungi was considered to be existing on the chromosome 6A. The ergot fungi requires a long time for the incubation period until it is taken away from infection. The essential effect of resistant gene did not surmise on the chromosome 6A that gene concerned with the physiological effect to restrain the growing up of a ergot fungi in the growing process of plants. |
