摘要
早抗1号是一个综合农艺性状较好且兼抗白粉病和条锈病的早熟小麦新品系,其亲本组合为:抗源2号×邯农2号。为给该品系的未来应用提供依据,用中国春21个单体系对其抗白粉病基因进行了分析。结果表明,这个基因位于2A染色体上。它可能是一个来源于我国野生二粒小麦的新的抗白粉病基因。
Zaokang 1 is a new early mature variety with better agricultural characters and resistance to powdery mildew and stripe rust, bred by Hebei Engineering College from a cross of Kangyuan 2 × Hannong 2. The (resistance) gene of Zaokang 1 to the powdery mildew was analysed with 21 monosomes of Chinese Spring. The (result) indicated that the resistance gene in this variety located at chromosome 2A. It could be the new resistance gene from wild Triticum dicoccoide of China.
