前言冬季低温寒流所造成的冻害是目前我省柑桔生产上存在的主要问题之一,除了从栽培技术措施上摸索一些有效解决的办法外,人工培育出抗寒优质的新品种是一项长远的和必要的措施。我省柑桔栽培历史悠久,品种资源丰富,曾在五十年代末到六十年代初期开展了群众性的柑桔资源普查工作,初步调查和整理了我省主要柑桔产区的资源情况,并开展了柑桔有性杂交育种工作。在此基础上我所于1972年以来,开展了柑桔抗寒优质新品种的培育试验。现将1972～1974三年的试验概况、结果和体会总结如下。
Introduction frost damage caused by the cold in winter is one of the major problems in citrus production in our province. Apart from exploring some effective measures for cultivation techniques and measures, it is a long-term task to cultivate new varieties of high-quality cold- And necessary measures. Citrus cultivation in our province has a long history and rich variety of resources. In the late 1950s and early 1960s, a mass census of citrus resources was carried out. The resources of the main citrus producing areas in our province were initially investigated and sorted out. And carry out the sexual cross-breeding of citrus. On this basis, since 1972, I conducted a cultivation test of new high-quality cold-resistant citrus varieties. Now 1972 ~ 1974 three years of test profiles, results and experience summarized below.
