Abstract

ABSTRACT Selecting new sweet potato genotypes that are adapted to the soil, climate, and cultivation conditions of the producing regions is necessary. Thus, the objective of this work was to evaluate the agronomic performance of experimental genotypes of white-fleshed sweet potato in commercial fields, seeking to evaluate their potential as commercial cultivars. The experiments were carried out in the municipalities of Presidente Prudente, Emilianópolis, Tarabai, and Álvares Machado in São Paulo state. The randomized complete block design with five repetitions was used in the experiments, where the genotypes UZBD-L1-04 and UZBD-L5-29 were evaluated along with the controls Ligeirinha Paulista, Canadense, and INIA Arapey. The assessed traits were tuberous root total yield, number of commercial tuberous roots, commercial tuberous root yield, average mass of commercial tuberous roots, percentage of commercial tuberous root dry mass, soluble solids, resistance to pest-caused damage, root length, diameter, and appearance. UZBD-L1-04 performed better than the other genotypes (the average of environments for tuberous root total yield was 31.76 t/ha), showing great potential as a commercial cultivar for the studied region.

试验白肉甘薯基因型在商品田的农艺性能

摘要选择适合产区土壤、气候和栽培条件的甘薯新基因型是十分必要的。因此，本工作的目的是评估白肉甘薯试验基因型在商业领域的农艺性能，试图评估其作为商业品种的潜力。实验是在圣保罗州的保诚总统、埃米利亚诺波利斯、塔拉拜和阿尔瓦雷斯-马查多市进行的。实验中使用了五次重复的随机完全区组设计，其中对基因型UZBD-L1-04和UZBD-L5-29以及对照Ligeirinha Paulista、Canadense和INIA Arapey进行了评估。评估的性状为块根总产量、商品块根数量、商品块根产量、商品块茎根平均质量、商品块块根干物质百分比、可溶性固形物、对虫害的抗性、根长、直径和外观。UZBD-L1-04表现优于其他基因型（块根总产量的平均环境为31.76t/ha），显示出作为研究区域的商业品种的巨大潜力。
