The fresh genotype 34_A1 was initially filed when you look at the 2004 when you look at the Slovenia (EuroBlight circle, )
It’s likely that particular isolates from various genotypes clustered together with her which have isolates of one’s 34_A1 genotype is items of one’s sexual reproduction that takes place inside Poland
The brand new gang of P. infestans isolates assessed within this research desired us to assess the intragenotype diversity of genotypes 34_A1 and thirteen_A2 somewhat. New genotype 34_A1 is the most widespread, represented by the 87 isolates off 237 checked-out P. infestans isolates. Earlier study to your P. infestans society build into the Poland have demostrated that sexual breeding is most likely taking place inside society . The dwelling analysis of studies from Boguchwala indicated that some of one’s P. infestans isolates were labeled additionally to the around three or a few groups (Fig. 3a, b). I allegedly noticed certain isolates that will be due to sexual breeding of isolates of your 34_A1 genotype (partly belonging to the eco-friendly class) in lieu of a result of mutation. Into the from year to year away from search, P. infestans isolates regarding one another mating versions have been noticed. In the Poland, the earliest isolates with the genotype were understood in the 2002 (one or two isolates). In the modern analysis, we discovered fourteen isolates of the second well-identified genotype of P. infestans, 13_A2, which quickly spread throughout Europe between 2005 and you will 2008 and is actually represented prior to now because of the not totally all isolates into the Poland . Notwithstanding seed potato imports out of Eu to Poland (anywhere between 2005 and you can 2014 the transfer fluctuated ranging from eleven.7 and 33 hundreds of tons), the newest thirteen_A2 P. infestans genotype stays rather rare. These two genotypes differed within the virulence affairs (Fig. 5a, b) and you will effectiveness metalaxyl.
