It should be represented in the unit of number of SCN eggs per 100cc of soil," said Lopez-Nicora. "The second information requested is a female index on PI 88788."

"The female index on PI 88788 is basically a number that represents the amount that specific population of SCN can reproduce on soybeans with the PI 88788 resistance gene," said Lopez-Nicora.... Continue reading
