小麦新品种品育8012白粉病抗性研究

Powdery Mildew Resistance Gene of New Wheat Variety‘Pinyu 8012’

品育8012是由山西农业大学小麦研究所选育,2018年通过山西省审定,亲本组合临优20165/济麦22,2020-2022年连续三年被列为山西省农业生产主推品种,该品种近免疫白粉病。为了解品育8012白粉病抗性,先进行亲本已知抗病基因检测,继而进行其它抗病基因检测,随后在山西、山东和河北3省15点田间鉴定进行验证试验。得出品育8012携带13个白粉病抗性基因,在山西、山东和河北多点对白粉病表现中抗乃至近免疫。品育8012可作为选育抗白粉病小麦品种的抗源加以利用。

Wheat variety‘Pinyu 8012’,selected and bred by Wheat Research Institute of Shanxi Agricultural University,was approved by Shanxi Province in 2018.The parent combination‘Linyou 20165’/‘Jimai 22’,has been listed as the main agricultural production variety in Shanxi Province for three consecutive years from 2020 to 2022,and this variety has demonstrated near-immunity to powdery mildew.To understand the powdery mildew resistance of‘Pinyu 8012’,the known disease resistance gene of the parents was first tested,followed by testing for other disease resistance genes,and the field identification tests were conducted at 15 experimental sites in Shanxi,Shandong,and Hebei.It was concluded that‘Pinyu 8012’carries 13 powdery mildew resistance genes,which is resistant to or even nearly immune to powdery mildew in Shanxi,Shandong and Hebei.Therefore,‘Pinyu 8012’can be a valube source for selection and breeding of powdery mildew-resistant wheat varieties.
