Names aside, the Zill family has invested about 80 years in the improvement of Mango variety. In all fairness, they deserve a lot of credit for their work.. Chances are good that although they have released a lot of new varieties recently, each one is an improvement on already well bred parents. What tastes good to one person may not taste good to the next, but the concensus seems to be that Gary has a grasp on the improvement process.. We should be careful how we describe a mans hard work. By discounting varieties it can be just as negative for a company as it is positive. By telling people that something is not worth planting you can create a narrow minded view limiting diversity. With power comes responsibility.
