摘要: 以4份抗裂番茄为母本,3份易裂番茄和1份抗裂番茄为父本,按照不完全双列杂交设计配制4×4的杂交组合,研究8个亲本和16个F1的裂果特性与果皮结构的关系,分析它们的杂种优势表现。结果表明,易裂基因型的果皮较薄,抗裂基因型的果皮普遍较厚,但也有果皮薄而抗裂能力强的基因型。裂果特性有明显的杂种优势,优势的方向在不同组合间有很大的差异。亲本的一般配合力对杂种后代的抗裂时间发挥了决定性作用。对利用结构特征改良番茄抗裂能力的潜力进行了讨论。

关键词: 番茄, 裂果, 果皮结构, 杂种优势

Abstract: According to diallel crossing design, 4×4 combinations from 4 female parents with crack resistance and 3 crack-susceptible male parents and 1 crack-resistant male parent were made. These 16 F1s and 8 parents were used to study relationship between crack characteristics and fruit skin architecture as well as their heterosis. Experimental results showed that fruit skin of crack-susceptible genotypes was much thinner than that of crack-resistant ones. But there were some crack-resistant genotypes with thin fruit skin. Crack characteristics displayed a strong heterosis but its direction depended on combinations. General combining ability played an important role on crack-resistant time of F1. The potential of improving crack capacity based on skin architecture was discussed.

Key words: Tomato, Fruit crack, Fruit skin architecture, Heterosis
