abstract

Recent legislation has authorized Federal Marketing Order standards for all Pacific Coast Bartlett pears. If size standards are invoked, they should take into account any variations in shape of pears produced in different districts. Study of fruit measurements in California suggests that sizes of Bartlett pears for canning may be determined satisfactorily by sorting the pears in a sample according to weight. This method has several advantages over the present one based on minimum diameters.
