“…Diaporthe species are economically important pathogens of soybean seed which cause seed decay. D. longicolla (Hobbs) Santos, Vrandečić & Phillips is the most dominant and the most aggressive pathogen of this complex (Petrović et al, 2018). This was confirmed by results in the current study.…”

Soybean is one of the most important industrial crops in the world. The rich nutritional content of the seed is the reason for the increased cultivation of this crop all over the world. However, a large number of phytopathogenic fungi that exist in soybean seeds can reduce the nutritional content, germination, and seed vigor. Soybean seed samples were collected from experimental fields in seven locations in Vojvodina Province, Serbia in the period 2016-2018. From each sample, 100 seeds were randomly selected. Seeds were surface-disinfested in 4% sodium hypochlorite for 5 min, washed two times in sterile water, and dried on a filter paper. All 100 seeds were placed in 20 Petri dishes with standard potato dextrose agar medium (PDA), five seeds in each, and incubated at 22 ± 2°C for seven days, under 12 h of alternating light/dark conditions. The first assessment was performed on the fourth day after isolation. The health status analysis of soybean seed showed that Peronospora manshurica, Macrophominaphaseolina, Botrytis cinerea, Cercospora kikuchii as well as the species from genera Alternaria, Diaporthe, and Fusarium had colonized soybean seed in Serbia over three years. Species from the genus Alternaria and Peronospora manshurica were dominant in all three examined years. Furthermore, it has been noticed that weather conditions, location, and cultivar significantly influenced the intensity of the infection. The results of this study have shown which pathogens pose a threat to successful soybean seed production and help in finding preventive measures to control these pathogens during vegetation.

“…A number of isolates used in this investigation was small because only a small quantity of isolates in the Diaporthe species were identified as D. pseudolongicolla (Petrović et al, 2018). In this research, the isolates of Diaporthe longicolla (Pl 027) and Diaporthe pseudolongicolla (CBS127269, CBS127270, and CBS127271 -Fig.…”

“…Most of them attack the soybean seed, decrease germination, and cause a poor seed quality. One of the major causes of a poor seed quality in most soybeangrowing regions worldwide is the Diaporthe seed decay (Li, 2011;Vidić et al, 2013;Petrović et al, 2018). This disease is caused primarily by the fungus Diaporthe longicolla, along with D. sojae, D. caulivora, D. aspalathi and the D. eres species complex, D. foeniculina, and D. radis (Li, 2011;Petrović et al, 2015;Petrović et al, 2016;Hosseini et al, 2020).…”

“…Nevertheless, a latently infected seed can have a normal appearance, without disease symptoms, but the germination, vitality, and quality will be reduced as a result of a latent infection (Kmetz et al, 1978). The isolates of D. longicolla were equally present on the soybean seeds and stems, while the D. pseudolongicolla was earlier isolated only from seeds (Petrović et al, 2018). A difference between these two species was that the isolates of D. pseudolongicolla become rapidly sterile when grown in a culture and lost their ability to form the reproductive organs.…”

“…A difference between these two species was that the isolates of D. pseudolongicolla become rapidly sterile when grown in a culture and lost their ability to form the reproductive organs. In many Diaporthe species, both anamorph (asexual) and teleomorph (sexual) stages have been described, as well as their ability to form pycnidia and perithecia (Petrović et al, 2018). The D. longicolla has long been described as a fungus without a teleomorph stage, whose pycnidia has the very long necks and releases the alpha conidia only.…”

The Aggressivness of Diaporthe longicolla and Diaporthe pseudolongicolla Isolates Tested by the Soybean Seed’s Artificial Inoculation

et al. 2021

This study’s objective was to determine if there was a difference in aggressiveness between the Diaporthe longicolla and the Diaporthe pseudolongicolla isolates infecting the soybean seeds. An artificial inoculation was performed under laboratory conditions and in a greenhouse on a soybean cultivar (Tisa) created in the breeding program of the Agricultural Institute Osijek and represented in a large-scale production in the Republic of Croatia. An attempt was made to discover whether the isolates of the recently described D. pseudolongicolla were more aggressive to the soybean seeds than the D. longicolla isolates, which have manifested a high aggressiveness to the soybean seeds throughout a series of earlier experiments. The D. pseudolongicolla isolates used in the experiment were isolated from the infected seeds pertaining to a wide production in the vicinity of Osijek. The experiments have demonstrated that there were statistically significant differences (P<0.05) in the aggressiveness between the isolates tested, with the D. longicolla isolate manifesting the highest aggressiveness in both trials.
