Abstract

The goldenberry (Physalis peruviana) is an exotic fruit that in recent years has acquired great importance in both the local and international markets; one of the limiting phytosanitary problems for this crop is vascular wilt caused by Fusarium oxysporum f. sp. physali, which causes losses of 80-90%. The management of this pathogen is difficult and so far, it is based on preventive measures; however, there are alternatives such as genetic resistance, which is one of the most effective and profitable measures for its management. Taking that into account, the objective of this study was to evaluate the reaction of 40 genotypes of goldenberry against F. oxysporum under greenhouse conditions, by means of pathogenicity tests. The experiment was conducted in a selected place in the city of Pasto (Nariño department, south of Colombia). It was carried out with 40 genetic materials corresponding to different genotypes, one commercial control and four replicates per experimental unit; the statistical design was completely randomized. The traits evaluated were plant height (cm), disease severity (%), AUDPC area under the disease progress curve (units), disease incidence (%) and degree of vascular discoloration. The genotypes 09U138 and 12U399 have greater plant height (50.19 and 47.36 cm), lower AUDPC (zero units), lower incidence (0%) and lower degree of vascular discoloration (zero), with statistical differences from the rest of the genotypes, including the control. Field evaluations should be conducted with the same isolation and other commercial controls, as this research is only a step forward in the search for the resistance of uchuva to F. oxysporum.
温室条件下秘鲁Physalis L.基因型对尖孢镰刀菌的响应
金莓(Physalis peruviana)是一种外来水果,近年来在当地和国际市场上都获得了很大的重视;该作物的限制性植物检疫问题之一是由尖孢镰刀菌(Fusarium oxysporum f. sp. physali)引起的血管性枯萎病,造成80-90%的损失。这种病原体的管理是困难的,迄今为止,它是基于预防措施;然而,遗传抗性等替代措施是其最有效和最有利的管理措施之一。考虑到这一点,本研究的目的是通过致病性试验,评估40个基因型的金梅在温室条件下对尖孢镰刀菌的反应。实验是在Pasto市(Nariño部门,哥伦比亚南部)的选定地点进行的。采用40个不同基因型的遗传材料,每个实验单元1个商业对照,4个重复;统计设计是完全随机的。评价的性状为株高(cm)、病害严重程度(%)、病害进展曲线下AUDPC面积(单位)、病害发生率(%)和维管变色程度。09U138和12U399基因型株高较高(50.19 cm和47.36 cm), AUDPC较低(0单位),发病率较低(0%),维管束染色程度较低(0),与包括对照在内的其余基因型差异有统计学意义。实地评价应采用相同的分离和其他商业对照进行,因为这项研究只是在寻找乌chuva对尖孢镰刀菌的抗性方面向前迈出的一步。
