为进一步挖掘新的小麦抗条锈病种质资源基因,利用流行于中国和以色列的4个小麦条锈病生理小种对以色列地中海沿岸相对较湿润的Beit-Oren、Bat-Shelomo以及Givat-Koach地区的野生二粒小麦30个基因型,分别进行了苗期抗条锈性鉴定,并分析其抗锈性差异.结果表明,来源于地中海沿岸3个地区的野生二粒小麦中有7个基因型对不同条锈病生理小种表现出了抗性水平,其中来自于Bat-Shelomo群体的基因型6-22,对国内流行生理小种条中32和以色列流行生理小种5006均表现出了较强的抗性,可作为新抗病基因材料加以研究和利用.

Wild emmer wheat, T. dicoccoides is rich in genetic diversity. Especially, T. dicoccoides is regarded as a promising source for stripe rust resistance. The stripe rust resistance gene, designated Yr15, YrH52 and Yr36 were detected in wild emmer wheat from mesic regions, Rosh pinna, Mt. Hermon and Galilee in the north of Israel, respectively. In order to identify and characterize novel sources of stripe rust resistance, seedling reactions of three populations collected from Mediterranean coast, Bet-Oren, Bat-Shelomo and Givat-Koach, to four prevalent stripe rust races, CY32 from China, and 5006, Y241 and 5331 from Israel were investigated. The results indicated that seven of thirty genotypes among the three populations were resistant to different races. 6-22 genotype from Beit-Oren population was resistant both to race CY32 and race 5006, and could be studied and used as a new naterial resistant to stripe rust.
