Self-incompatibility genotypes of 224 plants of Ipomoea trifida from six populations in Central America have been determined by genetic analysis of segregants in F1 families derived from cross-pollinations with the most recessive homozygote. A total of 49 different S-alleles was identified in these populations. From analyses of S-allelic interactions in heterozygous plants which were generated from cross-pollinations between plants possessing different S-alleles, a linear dominance hierarchy… CONTINUE READING
