“…Similar studies [18] have noted that the early maturing varieties are more susceptible. Other studies have also reported that the medium and late maturing varieties varied in their resistance levels to bacterial soft rot [19]. These, however, were not demonstrated entirely in our research because, except for late blight, no other differences in susceptibility under field conditions have been detected.…”

The aim of this work was to assess quality deficiencies in three potato cultivars (Christian, Roclas, and Cumidava) during the storage period. According to the results, the Roclas presented the highest level of susceptibility to pathogens; this, however, can be attributed to the dry rot that causes greater damage in this cultivar. No significant positive correlations between the plant’s vegetative parameters and the most dangerous diseases and pests in Christian were detected. There was a significant positive correlation between the biomass of the tubers and the silver scurf blemish disease, respectively between tuber numbers and dry rot in Cumidava and significant positive correlations between tuber numbers and the silver scurf blemish disease, between biomass of the tubers and dry rot, respectively between tuber numbers and wireworm larvae at Roclas. Altogether, we can conclude that the most susceptible cultivar was Roclas followed by Cumidava, while the least susceptible was the Christian cultivar.

“…A variabilidade na suscetibilidade de cultivares de batata para a incidência de bactérias pectolíticas é relatada em trabalhos de outros pesquisadores (Bains et al, 1999;Reeves et al, 1999). Ibrahim et al (1978) afirmam que a suscetibilidade à podridão causada por bactérias pectolíticas depende da concentração do inóculo, da temperatura, da cultivar, da idade fisiológica do tubérculo e do intervalo entre a lesão e a inoculação.…”

Reação de cultivares de batata à podridão mole causada por Pectobacterium carotovorum subsp. atrosepticum, por P. carotovorum subsp. carotovorum e por P. chrysanthemi

A podridão mole em tubérculos de batata (Solanum tuberosum), causada por Pectobacterium carotovorum subsp. atrosepticum, por Pectobacterium carotovorum subsp. carotovorum e por P. chrysanthemi, é uma preocupante doença que causa danos expressivos à cultura em todo o mundo. Como inexiste tratamento eficiente para a podridão mole, o desenvolvimento de cultivares resistentes é considerado o método mais eficaz para a redução de perdas causadas pela doença. Nesse sentido, quatro cultivares de batata foram avaliados quanto à resistência natural às pectobactérias, mediante redução de massa de tubérculos após 20, 24, 48, 72 e 96 h de inoculação com suspensões bacterianas. O delineamento experimental constou de um esquema fatorial com quatro cultivares, três bactérias e quatro repetições. Os resultados foram transformados em proporção e integralizados como área abaixo da curva de progresso da doença (AACPD). Para as três bactérias estudadas, a cultivar Asterix mostrou-se o menos suscetível à podridão mole, diferindo significativamente dos demais.

“…No cultivar has been reported immune or resistant to early blight but large number of cultivars across the world possesses moderately resistance to early blight. These are Quaggy Joe (Reeves et al 1999), Alta Russet (Lynch et al 2004 ), Sazava, Nikoleta, Marcela (Voral 2005 ), MegaChip (Groza et al 2007 ), Picasso, Victoria, Provento, Ramus and Milva (Alexandrov 2008 ).…”
