Selfed and Crossed Proportions of Avocado Progenies Produced by Caged Pairs of Complementary Cultivars

Abstract

Abstract Using a malate dehydrogenase isozyme system, it was possible to identify the pollen donor parent in progenies of avocado ( Persea americana Mill.) obtained by enclosing 2 cultivars of complementary flower type in a screenhouse with a beehive. The observed percentage of cross-pollination ranged from 7% to 92%. Isozymes are demonstrated to be a practical way of identifying hybrids.
