Variety screening identifies potatoes with resistance to zebra chip disease – AgriLife Today

AMARILLO – The Texas A&M AgriLife Research plant pathology team in Amarillo intentionally infected potato plants with psyllids positive with the bacterium that causes zebra chip, a deadly disease plaguing the potato industry for the past 15 years.

The outcome is some promising germplasm that will help in the battle against the costly disease, said Dr. Charlie Rush, plant pathologist.Rush and Dr. Fekede Workneh, senior research scientist, conducted the study funded by a grant from the Texas Department of Agriculture to look for potato varieties that have some resistance to zebra chip bred into them.

“If potato varieties with genetic resistance can be identified, growers will have another tool in developing a comprehensive integrated pest management program to battle against the disease,” Rush said.
