Abstract
|
|
|
|
The melon fruits obtained from the hybrid of Eunchun × Sungwhan were analyzed to compare the rind pigments, fruit quality, and isozymes to the parents. The rind color of the hybrid was resembled to Sungwhan. Pigments, such as carotenoids (lutein, violaxanthin, carotene) and chlorophylls, were observed in Sungwhan, whereas carotene was not detected in the F₁ hybrid. Little chlorophyll was observed, but more lutein was found in Eunchun. In soluble solid contents (SSC), Eunchun was higher than Sungwhan and the F₁ hybrid was similar to Eunchun. Fructose, glucose and sucrose were the same tendency to SSC. In total ascorbic acids, the F₁ hybrid was higher than Sungwhan, but lower than Eunchun. Significantly higher amino acids were detected in Eunchun than those of the other one. No differences were observed among the entries in electrophoretic band patterns of isozyme (PGI, PGM, 6-PGD and MDH) in cotyledons.
