早疫病菌在番茄的叶部(早疫病)、苗期基茎(轴腐病)、成株茎(茎腐病)和果实(果腐病)上引起病害。早疫病是这些病害中最具破坏性的一种，因此在育种中受到相当大的关注。早疫病的抗病育种已有60多年的历史，但栽培番茄缺乏强抗源，抗性的数量表达和多基因遗传一直阻碍着高抗病品种的发展。在一些野生种的材料中，已经发现了高水平的早期疫病抗性，但育种品系仍然存在供体亲本的不利园艺性状。最近，以种间杂交为基础建立了第一个控制早疫病抗性基因座的连锁图谱。这些图谱可能有助于标记辅助选择。本文综述了茄子-番茄复合体的生物学、遗传学和育种方面的研究现状。
Alternaria solani causes diseases on foliage (early blight), basal stems of seedlings (collar rot), stems of adult plants (stem lesions), and fruits (fruit rot) of tomato. Early blight is the most destructive of these diseases and hence receives considerable attention in breeding. For over 60 years, breeding for early blight resistance has been practiced, but the development of cultivars with high levels of resistance has been hampered by the lack of sources of strong resistance in the cultivated tomato and by the quantitative expression and polygenic inheritance of the resistance. In some accessions of wild species, high levels of early blight resistance have been found, but breeding lines still have unfavorable horticultural traits from the donor parent. Recently, the first linkage maps with loci controlling early blight resistance have been developed based on interspecific crosses. These maps may facilitate marker-assisted selection. This overview presents the current knowledge about the A. solani-tomato complex with respect to its biology, genetics, and breeding.
