Thwarting the warts: UPEI study seeks wart-resistant potato variety
Researchers on the College of Prince Edward Island are starting their seek for a potato selection extra proof against potato warts following a provincial financial lack of 300 million kilos of potatoes.
Final October, the Canadian Meals Inspection Company (CFIA) discovered the largest concentration of potato wart in many years in two potato fields. In November, the CFIA suspended all potato shipments to the U.S. to forestall the unfold of potato wart, later suspending home exports as properly.
Genome Atlantic, a biotech firm primarily based in Nova Scotia, gave the UPEI researchers $20,000 to discover a extra wart-resistant potato selection and stop future bans. This was one in all eight climate change-related projects funded by the Genome Atlantic Small-Scale Local weather Change Fund.
According to the CFIA, potato wart is a “quarantinable pest” and the one strategy to management it’s to restrict its spreading by way of contaminated soil, seeds and instruments. As soon as contaminated, the fields produce fewer potatoes, which grow to be unmarketable from deformities however don’t hurt people.
The CFIA reviews discovering potato wart in 34 fields on P.E.I. since 2000, and the export of seed potatoes from P.E.I. stays prohibited, even after the export of potatoes as meals to the U.S. resumed April 1. Greg Donald, common supervisor of the PEI Potato Board that represents all P.E.I. potato farmers, didn’t perceive the necessity for the ban.
“Over the past 21 years, I might most likely put all of the potato wart potatoes at the back of my pickup truck,” Donald mentioned.
Xiuquan (Xander) Wang, a UPEI affiliate professor engaged on the challenge, mentioned the funding from Genome Atlantic will go towards evaluating the genes of various potato varieties. By discovering a wart-resistant gene, the researchers might both modify present varieties to be extra resilient to ailments like potato wart or make a wholly new wart-resistant selection.
“There can be a really, very difficult course of to primarily commercialize a brand new selection,” Wang mentioned. “That’s one thing past our capability, however from a analysis perspective, it’s extra about offering some scientific data in order that they’ll not less than make the most of that when they’re at that stage to include or introduce some new varieties.”
“The altering local weather situation could be an excellent set off for this sort of potato illness.”
Richard Donald, a Genome Atlantic marketing consultant who’s unrelated to Greg Donald, mentioned the analysis on potato wart might present a broader understanding of how local weather change may have an effect on agricultural pests and ailments in Atlantic Canada.
“We felt that this was a well timed funding,” Richard Donald mentioned.
“The altering local weather situation could be an excellent set off for this sort of potato illness, so potato wart is one in all them, however doubtlessly [for] different ailments,” Wang mentioned.
Greg Donald added that local weather change has each execs and cons for potato farmers. By sowing a various vary of crops, utilizing much less soil and planting cowl crops that stop soil erosion, farmers are already adapting to the results.
“With the altering local weather, it’s creating extra alternatives for rising various kinds of meals,” Greg Donald mentioned. “On the unfavorable aspect, we’re seeing way more excessive climate situations.”
Farmers already noticed such excessive climate situations in 2020, Wang mentioned, when P.E.I. skilled a drought.
The technique of introducing climate-resistant potatoes is already getting used, in keeping with Greg Donald. However he mentioned extra analysis is required to deal with totally different pathotypes—sorts of organisms that trigger ailments like potato wart and will have an effect on new potato varieties.
“Now we have two totally different pathotypes right here of potato wart,” Greg Donald mentioned. “[It’s important] to ensure that these varieties are proof against each pathotypes.”
Greg Donald mentioned the farmers he works with are assured within the monitoring measures in place and dedicated to sustaining P.E.I.’s stature within the potato trade.
“Whether or not it’s managing a weed or an insect or no matter, it’s only to have a look at various methods … to handle that pest,” he mentioned. “Resistant varieties is one actually good technique. There’s different methods too, however that one is of curiosity and is one which’s being employed, and we’ll have to be taught extra about it.”
