加州大学戴维斯分校蔬菜作物系,是目前世界上主要从事芹菜育种和遗传学研究的极少数研究机构之一。与其芹菜生产占世界重要位置的加州芹菜业相适应,其研究在此领域中居领先地位。戴维斯分校研究计划的主要目标是培育抗病和抗虫,包括对枯萎病、晚疫病以及对潜叶绳具有抗性的品系。为了能解决目前和今后加州芹菜产业的需求,要制定一个有效的芹菜育种计划,其优先的主要任务是征集大量的种质资源和开展芹菜的遗传基础研究。目前已征集到300份的芹属种质材料,包括了商用品种和所有陆地栽培种以及几个野生种。尽管在该属中至少有15个种,但是在全世界的所有种质库中几乎还未加以阐述。因此,目前几乎还不知道它们在芹菜育种中的潜力。 加州大学戴维斯分校的育种计划强凋以下几个方面: 一、抗病和抗虫性育种 枯黄萎病是由尖孢镰刀菌(Fusarium Oxysp- The University of California Davis Vegetable Crops is one of the very few research institutes in the world that focuses on celery breeding and genetics. Its Celery is the leading celery producer in the celery industry in California, which occupies a significant portion of the world. The main goal of the Davis research program is to develop resistance and insect resistance, including lines that are resistant to blight, late blight, and leaf lint. In order to address the current and future needs of the celery industry in California, an effective celery breeding program should be developed whose priority is to solicit large amounts of germplasm and conduct genetic basic research on celery. So far, 300 parsley germplasm collections have been collected, including commercial varieties and all land cultivars, as well as several wild species. Although there are at least 15 species in this genus, almost all of the genebanks in the world have not yet been described. Therefore, little is known about their potential for celery breeding at this time. The breeding program of UC Davis is strongly withering in the following aspects: I. Breeding for resistance and insect resistance Fusarium wilt is a disease caused by Fusarium Oxysp-
