Abstract :

Wheat strip rust is the most devastating fungal disease in the north Provinces of Afghanistan, causes heavy losses on this staple food crop for the last two years. Therefore, the experiment was carried out under field conditions in 2023, to screen the most growing wheat varieties against stripe rust disease. A total of 18 different varieties were used for this study to find out the resistant varieties. The study revealed that, among all tested varieties no one was found with complet resistance reaction against strip rust (yellow leaf rust). 12 varieties such as Pat wheat, Hazardana lalmi, Zardana, Jawzjan, Kabali, Lalmi 17, Darulaman, Sarkha, Suleh, Wahdat, Chonta and Mazar-99 expressed moderately resistance reaction, while the other 6 varieties viz., Lalmi 4, Hazardana  Abi, safidak, roshan, Kabul 013, Lalmi 15 showed moderately susceptible response to disease, a visible effects on wheat yield and plant height were also exposed by rust in some varieties compared to others, however the 15.00 gr/plot), whereas the lowest yield collected from zardana (1213.33 gr/plot) and safidak uppermost yield harvested from pat wheat (2128.33 gr/plot), Kabali (1970 gr/plot) and chonta (17 (1248.33 gr/plot), in respect to height, the highest  wheat varieties were Sarkha 135.73 cm and Pat wheat 121.00 cm; while the lowest height recorded in Choonta 92.20 cm and  Suleh 92.73 cm.
