Abstract

The use of dwarf lines to obtain mini-tomato hybrid plants has led to agronomic and economic advantages. However, the benefits provided by dwarf parents in tomato hybrids of the Santa Cruz type remain unexplored. The aims of this study were to determine the agronomic enhancement in BC1F2 dwarf populations bearing characteristic fruit of the Santa Cruz type after the first backcross and to select populations with high agronomic potential and fruit quality. The experiment was conducted in a greenhouse using a randomized block design with 15 treatments and 4 replicates. Evaluated genetic materials included 11 BC1F2 dwarf tomato populations, both parents (recurrent and donor), and the cultivars (Santa Cruz Kada and Santa Clara). Traits evaluated included: mean weight, soluble solid concentration, number of locules, shape, pulp thickness, fruit longitudinal and transversal diameters, internode length, and plant height. Univariate, multivariate, correlation, and selection index analyses showed that mean fruit weight, transverse diameter, and pulp thickness increased significantly in dwarf populations after a single backcross, most of them exhibiting a fruit shape similar to that of the Santa Cruz type. The dwarf BC1F2 populations UFU-Sci#11 and UFU-Sci#12 showed high potential for obtaining lines and, subsequently, Santa Cruz type hybrids.

圣克鲁斯矮番茄BC1F2群体的农艺潜力

利用矮系获得小型番茄杂交种具有良好的农艺和经济优势。然而，矮亲本在圣克鲁斯型番茄杂交中所提供的益处仍未被探索。本研究的目的是确定首次回交后具有圣克鲁斯型特征果实的BC1F2矮化群体的农艺增强，并筛选具有较高农艺潜力和果实品质的群体。试验在温室内进行，采用随机区组设计，共15个处理，4个重复。评估的遗传材料包括11个BC1F2矮番茄群体，亲本(循环和供体)和栽培品种(Santa Cruz Kada和Santa Clara)。评价的性状包括:平均重量、可溶性固形物浓度、房室数、形状、果肉厚度、果实纵、横直径、节间长和株高。单因素、多因素、相关分析和选择指数分析表明，单次回交后矮化群体的平均果实重、横向直径和果肉厚度显著增加，大多数矮化群体的果实形状与圣克鲁斯型相似。矮秆BC1F2群体UFU-Sci#11和UFU-Sci#12在获得品系和随后的圣克鲁斯型杂交种方面表现出很高的潜力。
