Looks like hype for a private enterprise to gain profit not based on any real research of the pear. If the pear is really outstanding, the money in commercial production is the usual route.
They got someone with a pedigree to say the pear seemed to perform well in someone’s yard. I would not be the first in line to make the Perdue pear the Perdue’s family “road to riches”.
Of course, it could be a great pear, it just hasn’t been thoroughly evaluated yet. That would be a very expensive process, so the fact it hasn’t been done is not proof of any hesitation to submit it to more scientific evaluation beyond the cost.
I’ve read the Hass avocado was a chance seedling grown in someone’s yard that turned out the be perhaps the most enriching patent for a discoverer’s family ever. It turned out to be a great tree for the industry and completely dominates its field.
Here, Harrow Sweet functions as an almost perfect pear with nice spreading branches to go along with its other virtues, including FB resistance. Perhaps its greatest single virtue, besides the quality of the fruit is it’s precocity. Fruit on the third year after planting is common.
