南美叶疫病是植胶业的一个严重威胁。到目前为止,该病仅在拉丁美洲发生,同时很难经济地加以控制。最好的解决途径是培育抗病品系。本文描述了法斯通胶园公司于1949年开始进行的育种计划。提出了引种的巴西培育的无性系的产量数据。在利比里亚的隔离种子园,进行了感病与抗病无性系的新粗合的杂交,在危地马拉和巴西,筛选了这些杂交组合的抗病后代。在利比里亚检验了选出的抗病品系的产量,并提出了第一次病害检验的结果。
South American leaf blight is a serious threat to the plasticizer industry. To date, the disease has taken place in Latin America alone, and is difficult to control economically. The best solution is to develop resistant strains. This article describes the breeding program started by Faustoon Rubber Park in 1949. The production data of clones introduced in Brazil are presented. In the isolation seed orchard in Liberia, a new crude crosses of susceptible and resistant clones were conducted, and in Guatemala and Brazil, resistant progeny of these crossings were screened. The production of selected resistant lines was tested in Liberia and the results of the first disease test were presented.
