Abstract

ABSTRACT In the world the consumption of strawberries is very appreciated, both in natura or industrialized form. Brazilian production depends on the importation of strawberry seedlings from countries such as Spain, Chile and Argentina, which are cultivars improved in temperate climates and, consequently, not well adapted to the Brazilian tropical conditions. Thus, genetic breeding programs are essential for the generation of more adapted cultivars. The objective was to evaluate and characterize the performance of experimental strawberry genotypes. The statistical design adopted was in randomized blocks, with 12 treatments and 3 replications, the treatments consisting of seven experimental genotypes and five commercial cultivars. We evaluated the total production per plant (g/plant), average weight of fruits per plant (g/fruit), % of commercial fruits per plant, and morphological characterization. The experimental genotypes MFA443, MCA94, MDA23, MDA06 and MCA89 showed the highest strawberry yields per plant, respectively, 285 g, 254 g, 298 g, 295 g and 290 g, with emphasis on the genotype MFA12-443, which also presented the highest average weight of fruits (20.35 g) and percentage of commercial fruits (81%).

草莓实验基因型的产量及形态特征分析

摘要在世界范围内，无论是自然还是工业化形式的草莓消费都非常受欢迎。巴西的生产依赖于从西班牙、智利和阿根廷等国进口草莓幼苗，这些草莓幼苗是在温带气候下改良的，因此不太适应巴西的热带条件。因此，遗传育种计划对于培育更适应的品种至关重要。目的是评估和表征实验草莓基因型的性能。采用的统计设计是随机分组的，有12个处理和3个重复，处理由7个实验基因型和5个商业品种组成。我们评估了每株植物的总产量（g/株）、每株植物果实的平均重量（g/果）、每棵植物商业果实的百分比以及形态特征。试验基因型MFA443、MCA94、MDA23、MDA06和MCA89的单株草莓产量最高，分别为285克、254克、298克、295克和290克，其中MFA12-443的平均果实重量（20.35克）和商品果实百分比（81%）最高。
