“Sangbeak” (Perilla frutescens (L.) Britton), is a cultivar for leaf vegetable, from a cross between YPL5 (Ipdeulkkae1/ YCPL187) and “Namcheon” at the National Yeongnam Agricultural Experiment Station (NYAES), RDA, in 2003. The size of fully grown leaf is a important trait in delayed harvesting. The maximum leaf size of “Sangbeak” is 18.5cm, smaller than 21.4cm of a check cultivar, “Ipdeulkkae”1, leading to the constant leaf quality in delayed harvest. The fresh leaf yield of “Sangbeak” is 6% higher than that of “Ipdeulkkae 1” (5029 vs. 4742 kg/10a). For the leaf production, “Sangbeak” could be grown in whole area of South Korea. However, because of its late maturity, seed production culture is available in South Gyeongsang and South Jeolla provinces.
“Daeshin” (Perilla frutescens (L.) Britton), a new cultivar for leaf vegetable, was developed from a cross between YPL5 (Ipdeulkkae1/YCPL187) and Milyang2 at the National Yeongnam Agricultural Experiment Station (NYAES), RDA, in 2002. For the cultivation of leaf vegetable perilla, seeds are sown in narrow spacing of 10 × 5 cm and all branches are removed to harvest uniform leaves from main stem. Because of the narrow planting distance, it is difficult to distinguish seeds from soil in dark brown seed cultivar. Therefore the gray-white size color of “Daeshin” is very useful characteristic for easier sawing in perilla cultivation. “Daeshin” grow vigorously and yield high quality leaf. The fresh leaf yield of “Daeshin” is 9% higher than that of “Ipdeulkkae 1” (4,823 vs. 4,459 kg/10a). For the leaf production, “Daeshin” is adaptable to whole arable land in South Korea. However, the southern parts of Korea such as South Gyeongsang and South Jeolla provinces are appropriate for the seed production.

Foehn damage on rice plant is one of the important abiotic stresses in eastern costal area of Korea. To know the relationship between foehn impact and morphological traits of rice, wind tunnel method was used with 106 rice cultivars. Less influencing traits on foehn were short panicle, large panicle number per hill, thin panicle neck, and the flag leaf of narrow, short and thick. Leaf pubescence reduced the impact on foehn. 'Naepungbyeo' belong-ed to foehn tolerant varietal group, while 'Ansanbyeo' belonged to the opposite group. Three levels of root cutting treatment with two rice cultivars were conducted to evaluate the foehn impact using wind tunnel. The severity of wind damages was followed the sigmoidal curve duration of wind tunnel treatment were prolonged. Different responses of root cutting to wind tunnel treatment could be used to evaluate the severity of the foehn impact. 'Naepungbyeo' was one of the less implausible cultivars on foehn. 'Nae-pungbyeo' showed tolerant response to wind under 21% root removing treat-ment (20㎝ root cutting), however 'Ansanbyeo' was wilted under the same treatment. In case of 35 % root removing treatment(10㎝ root cutting), both rice cultivars failed to alive against foehn wind.
