| Abstract: | The objective of this study was to determine, under field conditions, the effect of the cereal cyst nematode ( CCN ), Heterodera avenae, on yield of wheat cv. ( Yocora Rojo ). The study was conducted in naturally-infested field with different nematode population densities in Al-Kharj during the 1994-1995 growing season .
Results indicated that the grain yield was highly affected by nematode infection.Crop loss reached up to 93.5 % in the highly infested site ( 90 cysts / 100 gm soil ). Both crop losses are very high indicating the serious threat of CCN on our wheat production . This is the first report in the Kingdom on crop losses of wheat due to CCN infection under field conditions |
