The effects of Rhizobium inoculant, compost, and nitrogen on nodulation, growth, dry matter production, yield attributes, and yield of pea (Pisum sativum) var, IPSA Motorshuti-3 were assessed by a field experiment. Among the treatments Rhizobium inoculant alone performed best in recording number and dry weight of nodules/plant. The highest green seed yield of 8.38 ton/ha (36.9% increase over control) and mature seed yield of 2.97 ton/ha (73.7% increase over control) were obtained by the application of 90 kg N/ha. The effects of 60 kg N/ha, Rhizobium inoculant alone and Rhizobium inoculant along with 5 ton compost/ha were same as the effect of 90 kg N/ha in recording plant height, root length, dry weight of shoot, and root both at preflowering and pod filling stages, number of mature pods/plant, number of mature seeds/pod, 1000-seed weight, green, and mature seed yields of pea.

This experiments were conducted to evaluate suitable plant-type and cultivars for producing fresh pod peanut from late seeding as succeeding crop, compared with early seeding as proceeding crop or single cropping. 12 cultivars according to grain weight and plant types, 6 virginia typed cultivars(ssp. hypogaea) and 6 shinpung typed cultivars(ssp. fastigiata), were used for early and late seedings. The plant growth and yield potential in early seeding were better than those in late seeding. But the ratios of dry/fresh pod and of mature pod in late seeding were higher than those of early seeding. The yield of fresh pod by cultivars in two seeding times showed significant correlation with pod scale such as fresh pod weight, 100-grain weight, and dry seed yield positively, but pod number negatively in early seeding only. Yield of fresh peanut between Virginia and Shinpung types didn't show significant difference in early seeding, but showed in late seeding. Average yield of Virginia typed cultivars showed significantly higher than that of Shinpung typed ones. This yield gap between two plant types was the same tendency on extending seedings to July 20.

땅콩의 낙협 저항성 유전 자원을 발굴하여 재배 및 육종의 소재로 활용하기 위하여, 우리나라 장려 품종 7종을 포함한 Virginia type 94품종, Spanish type 99품종 및 Valencia type 18품종등 합계 218품종을 공시하여 파종 후 개화까지의 소요 일수, 주당 성숙 협과수, 종실 100립중, 낙과와 자방병 사이의 인장강도 및 포장 낙협률등 주요 특성을 조사함과 동시에 낙협 저항성의 요인을 검토하였던 바 그 결과를 요약하면 다음과 같다. 1. 파종 후 개화까지의 소요 일수는 Spanish type 및 Valencia type의 품종들이 Virginia type의 품종들에 비해 짧은 편이었으며, 우리나라 장려 품종들은 비교적 짧은 편에 속하였다. 2. 주당 성숙 협과수는 Spanish type의 품종들이 Virginia type 및 Valencia type의 품종들에 비해 많은 편이었으며, 우리나라 장려 품종들은 비교적 많은 편에 속하였다. 3. 종실 100입중은 우리나라 장려 품종들이 소입중인 Spanish type 및 Valencia type의 품종들은 물론, 같은 대립중인 Virginia type의 품종들보다도 무거운 편이었다 4. 협과와 자방병 사이의 인장강도는 품종에 따라 다양하였으나, Spanish type의 품종들이 비교적 강한 편이었고 우리나라 장려 품종들과 Virginia type의 품종들이 비교적 약한 편이었는데, 포장 낙협률은 우리나라 장려 품종들과 Virginia type의 품종들이 비교적 높은 편이었고 Spanish type의 품종들이 비교적 낮은 편이있다. 5. 파종 후 개화가지의 소요 일수, 주당 성숙 협과수, 종실 100입중, 협화와 자방병 사이의 인장강도 및 포장 낙협률 사이에는 각각 높은 산관관계가 인정되었으며, 특히 포장 낙협률은 협과와 자방병 사이의 인장강도, 주당 성숙 협과수 및 종실 100입중 등 여러가지 요인들의 복합 작용에 의해 발현되는 형질인 것으로 생각되었다.

Compositional and quantitative changes of 4-desmethylsterols in soybean (Glycine max. cv. Gangrim) seed and pod at six stages of development from flowering were investigated. The content of 4-desmethyl-, 4-monomethyl- and 4,4-dimethylsterols in developing soybean seed and pod was found to vary between 0.16-0.35, 0.04-0.12 and 0.04-0.06%, respectively. The predominating 4-desmethylsterols were sitosterol, campesterol and stigmasterol. The proportion of sitosterol in seed decreased to 57.0% with maturation, while in pod increased up to 88.7%. ${\triangle}^{7,22,25}$ Stigmastatrienol estimated 7.5% was detected in the fully mature seed.

Lipoxygenase and Kunitz trypsin inhibitor protein of mature soybean [Glycine max (L.) Merr.] seed are main anti-nutritional factors in soybean seed. A new soybean cultivar, "Gaechuck#1" with the traits of black seed coat, green cotyledon, lipoxygenase2,3 and Kunitz trypsin inhibitor protein free was developed. It was selected from the population derived the cross of "Gyeongsang#1" and C242. Plants of "Gaechuck#1" have a determinate growth habit with purple flowers, brown pubescence, black seed coat, black hilum, oval leaflet shape and brown pods at maturity. Seed protein and oil content on dry weight basis have averaged 39.1% and 16.2%, respectively. It has shown resistant reaction to soybean necrosis, soybean mosaic virus, Cercospora leaf spot and blight, black root rot, pod and stem blight, and soybean pod borer. "Gaechuck#1" matured on 5-10 October with a plant height of 50 cm. The 100-seed weight of "Gaechuck#1" was 23.2g. Yield of "Gaechuck#1" was averaged 2.2 ton/ha from 2005 to 2007.

Three peroxidase (POD) cDNAs were isolated from dehydration-treated fibrous roots of sweetpotato (Ipomoea batatas) plant via the screening of a cDNA library, and their expressions were assessed to characterize functions of each POD in relation to environmental stress. Three PODs were divided into two groups, designated the basic PODs (swpb4, swpb5) and the anionic PODs (swpa7), on the basis of the pI values of mature proteins. Fluorescence microscope analysis indicated that three PODs are secreted into the extracellular space. RT-PCR analysis revealed that POD genes have diverse expression patterns in a variety of plant tissues. Swpb4 was abundantly expressed in stem tissues, whereas the expression levels of swpb5 and swpa7 transcripts were high in fibrous and thick pigmented roots. Swpb4 and swpa7 showed abundant expression levels in suspension cultured cells. Three POD genes responded differently in the leaf and fibrous roots in response to a variety of stresses including dehydration, temperature stress, stress-associated chemicals, and pathogenic bacteria.

The effects of Rhizobium inoculant, nitrogen, phosphorus, and molybdenum on nodulation, dry matter production, yield attributes, pod and seed yields, protein and phosphorus contents in seed of pea (pisum sativum) var. IPSA Motorshuti-3 were assessed by a field experiment. Among the treatments Rhizobium inoculant in combination with 25kg P and 1.5kg Mo/ha performed best in recording number of nodules/plant, total dry matter yield, number of pods/plant, number of seeds/pod, 1000-seed weight, green pod yield, green and mature seed yields of pea. The highest green pod yield of 15.37 t/ha ($97.05\%$ increase over control) and green seed yield of 9.6t/ha ($69.31\%$ increase over control) were obtained by inoculating pea with Rhizobium inoculant in association with 25kg P and 1.5 Mo/ha. The effects of 60 or 120kg N/ha were comparable to Rhizobium inoculant in most cases. There were positive correlations among yield attributes, yield, protein and phosphorus contents in seeds of pea. From the viewpoint of yield attributes, yield, and seed quality, application of Rhizobium inoculant along with 25kg P and 1.5kg Mo/ha was considered to be the balanced combination of nutrients for achieving the maximum output from cultivation of pea in Shallow-Red Brown Terrace Soil of Bangladesh.
