"In this greenhouse, we are producing new potato varieties of our standard
cultivated potatoes," Dr. Porter said. "We extract the seeds from this fruit
to get new plant material."
Right now, the process is very slow and time-consuming.
"We have to spend 10 to 12 years selecting in the field, testing at many
locations in the U.S., to find out what ones out of those thousands of new
individuals might be useful for new varieties," Dr. Porter said.
The new DNA-based tool will hopefully help develop new potato varieties
quicker, in five to six years, half the time currently needed.
Dr. Porter said their work is important for many reasons.
"Because potatoes are a very important crop, new varieties are worth
millions of dollars, and so developing new varieties is really important, it's
important for consumers, better quality potatoes, potatoes that are
produced with less risk for the environment and its important to growers
because they can more efficiently grow potatoes," said Dr. Porter.
Dr. Porter and Dr. Tan are also focused on developing potato varieties
resistant to diseases and pests. They have partnered with a team of
national and international researchers to develop and test
genomics-assisted tools in hopes to advance the breeding of crops such
as potatoes and sweet potatoes.
DNA based-tools have recently become available and are now widely used
to improve a variety of economically important crops.
“Our potato improvement program is very effective at delivering improved
potato varieties to Maine growers and beyond. The exciting new
DNA-based tools that will be developed in this research project have the
potential to speed up the delivery of new, higher quality, high yielding,
pest resistant potato varieties to Maine growers and the U.S. potato
industry,” Dr. Porter said.
The goal of the project is to generate DNA-based marker data and
combine their normal data from the field, apply that information using
computer-based models, and do predictions on what the best parent plants
are to speed the development of new potato varieties.
"The effort that we are putting towards this project is to be able to make
these advances for potato in particular," said Dr. Tan. "That means that
we are able to make potato breeding as advanced as breedings for other
crops. I think, to me, that's the most important part of this project."
This research project is funded with a $4.3 million grant from the U.S.
Department of Agriculture’s National Institute of Food and Agriculture
(NIFA).
Dr. Porter and Dr. Tan are part of the research group working to develop
applications for potato breeding along with researchers from Texas A&M
University, Cornell University, North Carolina State University, the University
of Minnesota, and Oregon State University.
