DETERMINATION OF THE REACTIONS OF SOME BREAD AND DURUM WHEAT VARIETIES TO THE WHEAT SEED GALL NEMATODE [Anguina tritici (Steinbuch) Filipjev]

This study was conducted to determine the reactions of some bread and durum wheat varieties against wheat seed gall nematode. In the varietal reaction experiment, widely grown in Turkey, 20-bread and 12-durum wheat varieties were used. Total infected grains and healthy grains for each variety were counted and recorded. A statistically significant difference at the level of 0.01 was found among the cultivars in terms of the number of infected grains (pieces / plant), the number of healthy grains (pieces / plant) and the rate of infected grains. Compared to the control, there was a 35.8% decrease in the number of healthy grains in infected plots due to the damage of wheat gall nematodes in wheat varieties. The number of infected grains and the highest rate of infected grains were obtained from a bread wheat variety from cv. Aldane. While different rates of infected grains were obtained from 23 of the varieties included in the experiment, infected grain formation did not occur in the other 9 varieties (durum wheat varieties; Mirzabey 2000, İmren, Şahinbey, Zühre, Yelken 2000, Altıntaş, and bread wheat varieties; Bağcı 2002, Konya 2002, Ahmetağa). According to the number and ratio of infected grains, durum varieties were more tolerant. As with many diseases and pests, using resistant or tolerant varieties is one of the most economical and environmentally friendly method to control wheat gall nematode.
