向日葵抗列当品种(系)筛选及其应用评价

摘要

为了全面评价不同向日葵品种(系)对列当的抗寄生性和其在生产中的应用价值,对‘TP3313’等50个食葵品种(系)、‘内蒙杂4号’等6个油葵品种(系)进行了田间自然寄生试验,结果表明:食葵‘TP3313’为对列当免疫的品种,且病虫害发生较轻,产量相对较高(261.11 kg/667m2),因而具有极高的推广应用价值;‘TP3314’为高抗列当品种,但是受向日葵菌核病危害较重,产量为219.64 kg/667m2;‘SH361-L’、‘SH338-M’等8个品种表现为中感,属耐列当品种(系),并且产量相对较高,在生产中具有一定的应用价值.%Field experiments were carried out to evaluate the resistance of 50 edible and 6 oil sunflower varieties to Orobanche cumana and the application potential in sunflower production.The result showed that the edible sunflower ‘TP3313’ was immune to O.cumana.Combined with light occurrence of diseases and insect pests,and relatively high yield (261.11 kg/667m2),‘TP3313’ was identified as a variety with high application potential.‘TP3314’ showed high resistance to O.cumana,but it was easily infected by sunflower sclerotinia,and the yield was 219.64 kg/667m2.‘SH361-L’、‘SH338-M’ and other 6 varieties were tolerant to O.cumana,and the yield was relatively high.These varieties had a certain application value in production.
