莫桑比克不同腰果品系对叶果回枯病的抗病性调查研究

Survey for the Resistance of Different Cashew Clones to Leaf and Nut Blight in Mozambique

在田间自然发生条件下,研究莫桑比克9个高产优良腰果品系对叶果回枯病的抗病性。结果表明:腰果品系4.1AD叶片高感,果实感病;腰果品系5.12PA叶片和果实均为感病;腰果品系CCS27和CM8均为叶片感病,果实中抗;腰果品系A103叶片中抗,果实高抗;腰果品系H1叶片高抗,果实中抗;腰果品系7.10PA、19.5AD和C5.59叶片和果实均为高抗。在参试腰果品系中,未发现叶片免疫品系,也未发现果实高感或免疫品系。

The resistance of 9 cashew clones to leaf and nut blight were evaluated in the study under field conditions in Mozambique. The results showed that, clone 4.1AD was highly susceptible on leaf and susceptible on fruit. Clone 5.12PA was susceptible on both leaf and fruit. Both of the clones CCS27 and CM8 were susceptible on leaf and resistant on fruit. Clones A103 was resistant on leaf and highly resistant on fruit. In contrast, clones HI was highly resistant on leaf and resistant on fruit. Clones 7.10PA, 19.SAD and C5.59 were highly resistant on leaf and fruit. No immune clone on leaf or highly susceptible and immune clone on fruit was observed in the study.
