Would someone please direct me to research that proves or disproves the following statement. " phenotypic "plus" tree selections do not generally yield genetically superior progeny." I am looking into the question of "high grading." It has been said and seems intuitively correct that the practice of "cutting the best and leaving the rest" will lead to genetic decline in the offspring of "the rest." True or false.
