The allelic segregation of 13 isozyme loci in hand-fertilized heterozygous cherimoya trees (Annona cherimola Mill.) has been studied. We analyzed 63 locus x progeny combinations and found non-Mendelian segregation in 12 cases. The sequential Bonferroni method revealed only eight cases of non-Mendelian segregation; these have been investigated with several chi-square tests to discover what processes were involved. Gametic selection appears to be the main contributor, although zygotic selection seems also to play a part.
