مكافحة مرض تخطط الأوراق على الشعير باستخدام الطفرات

الملخص EN

This study was conducted to evaluate ten mutants of barley against barley stripe disease incited by Dreschlera graminea.

These mutants were obtained from Arivat and Numar cultivars after treatment with chemical and physical mutagens.

Plants were inoculated by the sandwich method in the laboratory and then transferred to the field.

The healthy looking plants were selected for four successive seasons (1985, 1986, 1987 and 1988).

The final selection for resistance was made at the end of 1988 season.

Resistant lines showed also high productivity in term of weight of 1000 grains.
