Breeding of“Pudamai 5”and Study on the Breedinq Way for Resistant to Powdery Mildew of Barley

Barley varieties in Fujian province had been seriously infected by Powdery Mildew,it heav-ily limited the increasement of yield,so the high quality and disease-resistant variety─ “Mushigang3”were used to crossed with”pudamaiyand a new feeding barley variety with good-harvest,high quality and disease-resistant-pudamai 5 have been bred,it made a breakthrough progress in Powdery Mildew resistant breeding.The main experience were showed as follow:to make a correct objetion of selection,give prominence Powdery Mildew resistant and good-har-vest characteristic,open up disease resistant resources in extensive,make scientific crossing de-sign,create profitable condition for disease,select vigorous disease-resistant plant,propagate seeds twice a year,speed up demonstration and popularization.
