A new cultivar of Rosa hybrida “Orange Flash” was selected from the progenies of a cross between “Lora” and “Timeless” at the Gyeonggi-Do Agricultural Research and Extension Services in 2000. It was finally selected in 2004 after investigation of the characteristics for three years (2002-2004). “Orange Flash” was developed for a standard type cut flower. The major characteristics of “Orange Flash” are 107stems/m2/year in yield, 24.8 in petal number and 10.9 days in vase life. The cultivar was applied for a variety protection in 2005, and was released to commercial growers in 2006.

A new cultivar of Rosa hybrida “Pink Flash” was selected from the progenies of a cross between “Red Sandra” and “Neon” at the Gyeonggi-Do Agricultural Research and Extension Services in 2000. It was finally selected in 2004 after investigation of the characteristics for three years (2002-2004). “Pink Flash” was developed for a standard cut flower. The major characteristics of “Pink Flash” are 132stems/m2/year in yield, 57.7 in petal number and 8.0 days in vase life. The cultivar was applied for a variety protection in 2005 and was released to commercial growers in 2006.

Three interspecific hybrid populations, Glycine max/G. gracilis, G. max/G. gracilis, and G. max/G. soja, were developed for genetic analysis. Genetic inheritance of 8 quantitative traits (days to flowering, days to maturity, reproductive period, leaf shap
