| Abstract | ||
| Survey of barley diseases was carried out under rainfed conditions in the Northwest Coast and North Sinai as well as under sprinkler irrigation in the new lands at Nubaria area. Under rainfed condition, physiologic spotting (boron toxicity) was the major problem which affected barley plants. Nest blotch was recorded in some locations but the severity was somewhat low. Scald, covered smut, and barley stripe were limited to some locations with low severity. Under sprinkler irrigation in the new lands, net blotch was presented as a major disease with high severity and incidence. Two barley genotypes were selected as highly resistant to net blotch under sprinkler irrigation in the new lands. Resistance to powdery mildew was exhibited by 28 barley genotypes out of 302 genotypes evaluated. A total of 391 barley genotypes were tested for tolerance to spotting out of which 15 genotypes were selected as highly tolerant. | ||
