Abstract EN
Eighteen wheat cultivars were grown in Marrow and Moshaqar Agricultural Stations during two successive seasons (1988/89 and 1989/90) in order to explore their response to infection with powdery mildew disease caused by Erysiphe grammis Dc.
f- sp.
tritici Marchal.
Twelve of these cultivars (Korifla, Waha, Stork, Celta, Acasad 65, Wascana, Jori, Kranish, Coccorit, CISB, Bt 149, and Morocco) were recently introduced to Jordan, while the other six (Hourani 27, Jubeiha, Sham 1, F8, Deir Alla 5, and Deir alia 7) are locally developed cultivars.
Morocco is included as a susceptible check.
The experiment was conducted in a randomized complete block design with four replicates.
The results indicated that Korifla, Waha, Stork, Sham 1, Celta, and Acsad cultivars were significantly better than the chcck Morocco and local cultivars at 5% level of DMRT.
During the two growing seasons, these cultivars showed a significant reduction in disease incidence and severity irrespective of the difference in their values between stations.
Differences in resistance among cultivars were found in the two years of study.
Cultivars reaction almost showed the same trend in the two stations.
Korifla was found immune to the disease while Waha, Stork, and Sham 1 consistently gave a resistant reaction.
Response of local cultivars ranged between moderately susceptible to susceptible, while Morocco was highly susceptible.
Significant differences in yield were found between cultivars as a result of powdery mildew infection.
The total dry master weight and grain weight of resistant Korifla, Waha, Stork, and Sham ! were significantly higher than local cultivars and much higher than the cultivar Morocco.
