Abstract

Genetic diversity is important in breeding program. Fusarium wilt resistant is one of the character that desired in the superior variety in shallot. This study was aimed to obtaining the genetic diversity based on morpholigical marker, ISSR moleculer marker, and resistant to wilt fusarium disease character of 19 Indonesian shallot genotypes. The experiment used randomized complete block design, with three replications, and shallot genotypes as a treatment. Fusarium oxysporum f.sp cepae was isolated from shallot plant that cultivated in Brebes, Central Java was used in this study that artificially innoculated on the shallot genotypes. The results showed that there were genetic diversity based on morphological character, ISSR moleculer marker, and fusarium wilt resistant. Batu Ijo and Rubaru were more resistance than the other genotypes based on incubation periode, disease incident, and infection rate.
