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.

In order to breed high yielding good quality leaves mulberry cultivar, which is essential for silkworm rearing, the characteristics of newly bred mulberry strain were surveyed. Materials and Methods: materials -Mulberry Jamgsang 123 which is registered as newly bred mulbery cultivar Suilppong -Sikworm Baegogjam nd Daesungjam were reared for practical leaves quality examination in spring and autumn, respectively by feeding Jamsang 123 leaves (omitted)
