The tallest culm length was observed in Geonganghongmi cultivar grown in coast area, and culm length was always taller in coast area than that of inland area among these three red rice cultivars. However, number of tiller per rice plant was not affected by different cultural area. Number of spikelets per panicle was much more increased in inland area. Regional difference in number of spikelets per panicle was only observed in Jeongjinju cultivar. Among these red rice cultivars, the highest brown rice yield was Jeongjinju rice cultivar having 702kg in inland area and 692kg in coast area, respectively. The $L^*$ values, which expresses the brightness, were in the range of 36.3 ~ 36.7, 36.7 ~ 37.0, and 38.7 ~ 39.6 in Jeogjinju, Hongjinju, Geonganghongmi rice cultivars, respectively. The $a^*$ values, which expresses the redness positively and greenness negatively were in the range of 12.3 ~ 12.8, 12.2 ~ 12.3, and 12.1 ~ 11.9 in Jeogjinju, Hongjinju, Geonganghongmi rice cultivars, respectively. In addition, the b values, which expresses the yellowness positively and blueness negatively were in the range of 13.8 ~ 14.0, 13.6 ~ 13.5, and 14.9 ~ 14.7 in Jeogjinju, Hongjinju, Geonganghongmi rice cultivars, respectively. Anthocyanidin content ranged 524 to $610{\mu}g/g$ dry weight basis. Cyanidin content was 11.4 to 14.0 times higher than that of delphinidin under coast and inland area. Among these rice cultivars, anthocyanidin content was always higher in rice cultivar grown at coast area. Highest head brown rice rate was only observed in Geonganghongmi to 95.2 at coast area and 95.4 inland area, respectively. Protein content was always higher in coast area than that of inland area. The lowest protein content was measured in Jeogjinju and amylose content was relatively increased in inland area compared to that of coast area. Consequently, in considered with brown rice yield and pigment content, Hongjinju rice cultivar was recommended in optimal pigment rice cultivar in eastern coast of Gyeongsangbuk-do Province.

Typhoon "MAEMI", happened in September 2003, hit the great damage to Gyeongnam province area. Especially, rice plant was lodged or severe leaf damage was caused. This study was conducted to find out the extents of leaf damage among different rice cultivars, and to evaluate rice yield and eating quality due to leaf damage after typhoon. Rice cultivars torn off over half of the flag leaf length (FLL) were one medium-late maturing cultivar (Donginl), medium maturing cultivar (Yeonganbyeo), eight early maturing cultivars (Samcheonbyeo, Jounghwnbyeo, Munjangbyeo, Taebongbyeo, Odaebyeo, Samhaegbyeo, Sobaegbyeo, Sinunbongbyeo), two long-il type cultivars (Samgangbyeo, Namcheonbyeo), and three special use cultivars (Heukseonchalbyeo, Jinbuchalbyeo, Yangjobyeo). Cultivars torn off below 1/10 FLL were eight medium-late maturing cultivars (Chucheongbyeo, Daecheongbyeo, Saechu cheongbyeo, Donganbyeo, Daeyabyeo, Hwamyeongbyeo, 방eongsanbyeo, Dongjinbyeo) and two medium maturing cultivays (Donghaebyeo, Gumobyeo2). The rest cultivars were tore off by 1/10∼1/2 ELL. In yield components, the longer was flag leaf damage, the lower was ripened grain ratio, grain weight and brown/rough rice ratio, which was severly impacted to late than to ordinary season cultivation. However, rice yield did not decrease up to tearing by 1/10 ELL. Head rice ratio decreased from flag leaf tearing over 1/10 ELL in late season cultivation. The longer was flag leaf damage, the lower was eating quality, which could not show significantly different.

Alternaria spp.were predominantly isolated from the abnormal leaf spot lesions of pear cultivars Niitaka and Nijiiseiki. Alternaria isolates from the cultivar Niitaka were not pathogenic to both cultivars, but the isolates from the cultivar Nijiiseiki developed typical lesions of black leaf spots and were identified as A. kikuchiana. However, no typical abnormal leaf spot lesions were produced by the Alternaria isolates. Foliar spray of twelve different agrochemicals including lime sulfur, either alone or in combinations, with 7 times applications from April to July failed to reduced the disease development. Application of 17 different pesticides including fungicides, insecticides and herbicides currently used in pear orchards did not cause leaf injury similar to the abnormal leaf spot. Simulated acid rain of as low as pH 3.0 did not incite any leaf lesions alike the abnormal spot lesions. Mineral contents in the leaves of both cultivars did not differ significantly between the healthy leaves and those with abnormal leaf spots. When cuttings of pear tree were obtained in February from newly emerged twigs of the healthy or the diseased trees of Niitaka and planted in sand in the greenhouse, only those from the diseased trees developed typical leaf lesions of the abnormal spot. These results indicate that abnormal leaf spots are caused by unknown systemic agents in pear trees, rather than by Alternaria spp., chemical injury or acid rain.

Soybean [Glycine max (L.) Merrill] crops, grown in a rice soybean rotation, can suffer when grown in soil with excessive moisture. The objective of this work were to determine the reduction in growth and yield, responses of vegetative and reproductive growth of soybean to excessive soil moisture achieved by prolonged irrigation. Responses of different cultivars were determined at growth stages from V6 to R8 to clarify the sensitive growth stages or characteristics to excessive soil moisture. Cultivar differences in response to excessive soil moisture condition were conspicuous in seed dry weight and harvest index (HI) but not in the response of seed number or pod number per plant. The timing of irrigation causing the condition of excessive soil moisture influenced the vegetative or reproductive traits. Soybean plants were more affected by irrigation commencing at the pre-flowering than at the post-flowering stage. Post-flowering irrigation did not reduce growth of vegetative organs significantly; in fact the growth of stems and leaves was facilitated by the prolonged irrigation commencing at flowering. Differences between cultivar response to prolonged irrigation were assumed to relate to the reduced amount of assimilates translocated to the reproductive organ.

Cruciferous vegetables are rich in biologically active compounds such as glucosinolates and have various health benefits. Among these vegetables, Kimchi cabbage (Brassica rapa L. ssp. Pekinensis) is one of the most popular leafy vegetables due to the presence of the highest amounts of numerous vital phytonutrients, minerals, vitamins, and antioxidants. This study aims to investigate the effects of six cultivars (Chundong 102, Asia No Rang Mini, Hwimori Gold, Asia Seoul, Wol Dong Chun Chae, and Asia Bbu Ri) on hairy root induction and glucosinolate biosynthesis in the hairy root cultures of Kimchi cabbage. Seven different glucosinolates, in this case sinigrin, gluconapin, glucoerucin, glucobrassicin, 4-methoxyglucobrassicin, gluconasturtiin, and neoglucobrassicin, were detected in the hairy root cultures of Kimchi cabbage. Among the different cultivars, Asia No Rang Mini was the most promising candidate for hairy root stimulation, as it achieved the highest values for the growth rate, root number, root length, transformation efficiency, and total glucosinolate content. Overall, the Asia No Rang Mini cultivar of Kimchi cabbage performed best as a promising cultivar hairy root culture for glucosinolate production.

The key to development of barnase-barstar transgene based hybrid seed technology is the availability of tightly regulated tapetum specific promoter, as any leaky expression of the barnase gene leads to several unintended effects. In the present study, we used two different tapetum specific promoters i.e. promoter of the RTS gene isolated from rice cultivar IR64 and the OsG6b promoter from japonica rice cultivar Hayayuki to express the barnase gene in rice transgenic lines. While viable male sterile transgenic lines could not be obtained with RTS promoter we could develop single copy male sterile lines when the barnase gene was expressed under the OsG6b promoter.

Shiitake mushrooms (Lentinula edodes) containing ${\beta}$-glucans may be beneficial for human health; they have been used in the treatment of cancer, hypertension, and high cholesterol levels. The objective of this study was to determine the ${\beta}$-glucan content in different sections of the fruiting bodies and mycelia of ten shiitake mushroom cultivars. The measured ${\beta}$-glucan content ranged from $20.06{\pm}1.76%$ to $44.21{\pm}0.13%$ in the pileus sections, and from $29.74{\pm}1.40%$ to $56.47{\pm}4.72%$ in the stipe sections. The results of this study indicate that the variance in ${\beta}$-glucan content dependent on the shiitake cultivar, and that the ${\beta}$-glucan content is higher in the stipe than in the pileus.
