Enzyme electrophoresis was used to estimate genetic diversity and population structure of maize, Zea mays L. (Graminales) in Korea. In nine populations, fourteen of the 24 loci (58.3 %) showed detectable polymorphism. Genetic diversity (0.205) was higher than average values for species with similar life history traits. Although our data are relatively small and the landraces not direct ancestors of cultivar, apparently the domestication process has eroded the levels of genetic variation of maize. The recent cultivars were found to have fewer alleles per locus (1.42 vs. 1.56), fewer alleles per polymorphic locus (2.27 vs. 2.33), lower percent polymorphic locus (33.3% vs. 41.7%), and lower diversity (0.159 vs. 0.185) than landraces. These genetic diversity parameters indicated that the cultivar populations were genetically depauperate relative to landlaces. The GST value of nine populations was 0.239. Nearly 76% of the total genetic diversity in Zea mays was apportioned within populations. The indirect estimate of gene new based on mean GST was moderate (Nm=0.80).

We bred a mulberry cultivar named 'Saealchan' through local adaptability test, which is under registration as a new cultivar for fruit production. Local adaptability test had been carried out at four local places (Jeonju, Gongju, Jangseong, and Sangju) for five years from 2013. This variety 'Saealchan' belongs to Morus alba L. selected from seedlings collected from mother mulberry 'Shimheung'. Saealchan was resistant to popcorn disease and high yielding variety in fruit productivity by 194% compared to control cultivar 'Shimheung (Morus alba L.)' for three years. Although fruits of 'Saealchan' was smaller in size and lower in sugar content of mulberry fruits compared to control variety 'Shimheung', it showed strong resistance to sclerotial disease compared to 'Shimheung'.

New triploid mulberry cultivar, Suilppong was bred among selected lines from F$_1$ seedlings obtained by crossing the female, artificial tetraploid No. 411 which obtained from Chungilppong seedlings, and the male, Kugsang 21. Local adaptability test has been carried out at four places (Suwon, Kongju, Jeonju and Jangsung) for five years since 1997. Leaf quality was tested by silkworm rearing for two silkworm rearing seasons (spring and autumn) at Suwon in 2000. Suilppong was recognized to be superior in productivity to control cultivar, Kaeryangppong. The new cultivar, Suilppong, has following agronomic characteristics as compared with Kaeryangnppong, which is leading cultivar widely cultivating in Korea. It is belonging to Morus alba L. with mixed shapes from the ovate to 5 lobated leaf shape, sprouting in spring nearly the same to the Kaeryangppong (Morus alba L.), high leaf yielding of 20% compared to Kaeryangppong (Morus alba L.). It is adaptable to everywhere except the places where cold damage occurs frequently in Korea. Suilppong is recommended to rear silkworms not only in spring but also in autumn besides for young silkworms.

This study was carried out to develope new zoysiagrass cultivar 'Senock' (Patent registration: 10-2003-0072018). Artificial crossing between collected lines of Z. sinica and Z. matrella (collected in South Korea) was conducted to develope F1 plant (CSM) which was cultivated at field for open self-pollination. Among the open pollinated progenies, CSM8 (Senock) showed superior performance in color and density rating. 'Senock' showed genetically dark green color, with medium leaf width ($3.1\pm0.17mm$), low plant height ($14\pm5.67cm$), and wide leaf angle ($67.3\pm11.1degree$). Height to the lowest leaf blade of this cultivar was $2.0\pm0.14cm$, which may allow low mowing height. Specific bands with primer number OPB7 by RAPD analysis can be used for cultivar identification.

New mulberry cultivar, Hansungppong, was bred among selected lines from F1 seedlings obtained by crossing the female, Yongcheonppong, and the male, Kugsang 21. Local adaptability test has been carried out at two places (Suwon and Chunchun) for four years since 1995. Leaf quality was tested by silkworm rearing for two silkworm rearing seasons (spring and autumn) at Suwon in 1998. Hansungppong was recognized to be superior in productivity and cold resistance to control cultivar, Yongcheonppong. The new cultivar, Hansungppong, has following agronomic characteristics as compared with Yongcheonppong, which was strongest leading cultivar against cold injury in Korea. It is belonging to Morus alba L. with the ovate leaf shape, sprouting in spring nearly the same to the Yongcheonppong (Morus alba L.), high leaf yielding of 10% compared to Yongcheonppong (Morus alba L.) and the high degree of cold resistance. It is adaptable to everywhere in Korea. Hansungppong is recommended to rear silkworms not only in spring but also in autumn besides for young silkworms.

A new standard carnation Dianthus caryophyllus 'Pink Beryl' was bred from a cross of red standard cultivar 'Francesco' and purple standard cultivar 'Saturn' in 1996 at the National Institute of Horticultural & Herbal Science. After investigation of the characteristics for 4 years from 1997 to 2000 and registered to the official breeding variety of Rural Development Administration in 2000. 'Pink Beryl' is pink standard cultivar with round edge of petal for cut flower. It has medium resistance to Fusarium wilt. To avoid calyx splitting caused by high temperature, this cultivar is recommended to grow over $8^{\circ}C$ at night and under $25^{\circ}C$ at days during flower bud differentiation period.
