<![CDATA[ An experiment to study the inheritance of sweetness in sweet corn has been conducted since May to October 2004 in Arjasa, Jember region and at Seed Technology Laboratory of Agricultural Faculty – University of Jember. Randomized Complete Block Design with sub-sample was used in this study and four replicates. The result showed that genotypes had significantly different on all observed parameters and sugar content heritability value is 20.33%. The gene that determines sweetness had a linkage with wrinkled seed type character. Self-fertilization of sweet corn produced 100% wrinkled seeds. It indicated that wrinkled seed was controlled by recessive homozygous gene. On the other hand, self-fertilization of smooth seed produced two ear types, the first type was 100% smooth seed, which meant that it was controlled by dominance homozygous gene; the other produced smooth seed and wrinkled seed by 3:1 ratio, indicated that it was controlled by heterozygous gene. Key words: sweet corn, sweetness, heritability.]]>
