云南农业科技人员近年来对不同栽培模式(净栽和混栽)下采集的113份感染小麦条锈病的新鲜叶片,从罹病叶片中直接提取罹病组织的DNA,利用我国及云南省的5个小麦条锈菌主要流行小种(条中32,条中29,条中31,条中23和水源类型)特异的分子标记对小麦条锈菌生理小种进行分子检测,以明确不同栽培模式对小麦条锈菌群体结构的影响。 In recent years, Yunnan agricultural science and technology personnel in different cultivation modes (net and mixed planting) 113 pieces of wheat stripe rust infection of fresh leaves, diseased leaves directly extracted diseased tissue DNA, using our country and Yunnan Province, five wheat The molecular markers of stripe rust wheat races were detected by using molecular markers specific to the main epidemic races of stripe rust (strains 32, 29, 31, 23 and water type) Effect of Stripe Rust Population Structure.
