A new graft cactus (Gymnocalycium mihanovichii) cultivar ‘Suyeon’ was developed from a cross between two pink with black breeding lines ‘9603010’ and ‘9603026’, by line selection at the National Horticultural Research Institute, Rural Development Administration in 2005. It was developed with the aim of breeding a cultivar showing vigorous growth and multiple colors. A line ‘9603010’ was derived from a cross between a black line and a pink line. Investigation into characteristics was conducted three times from 2003 to 2005. The color of both body and tubercle was pink with black. The shape of the globe was round and it had 7 to 9 deep ribs. The spine was short and straight, and its color was brown. Growth was retarded compared to a comparative cultivar ‘Ojack’, on the other hand, showed good propagation capability, setting 11 tubercles per globe. Characteristics of the cultivar could be maintained by vegetative propagation. Growers should take care to protect them from strong sun light and virus infection.

AFLP markers were successfully employed to detect genetic relationship and genetic variation within and between Oryza species. Analysis of 59 accessions of Oryza species with six AFLP prim er combinations detected a total num ber of 715 polym orphic bands

MITEs (miniature inverted-repeat transposable elements) are one of the major transposable elements in maize. We have applied MITE-AFLP technique to study the genetic diversity and genetic relationship among 25 elite maize inbred lines. While MITE-AFLP fra
