This study was investigated the quality characteristics of muffins which were prepared with whole waxy sorghum flours. Muffins were made with different sorghum flour contents of 10, 30, 50 and 100% substitution for wheat flour. The crude protein and fat contents of muffins were not different among samples, but the crude ash content was determined to increase with increasing content of sorghum flour. The specific gravity of the sorghum muffin batter as well as the weight and uniformity index of the sorghum muffins, were not significantly different from those of the control. The volume of muffins was found to decrease significantly when 100% sorghum flour was substituted for wheat flour. In terms of color, the L and b values of muffins were decreased with increasing contents of sorghum flour, and the a value was increased. The sensory test revealed that the hardness and adhesiveness of muffins was increased with the addition of sorghum flour, but springiness and chewiness decreased. According to the results of a sensory evaluation test, the flavor, taste and texture of muffins were reduced with the addition of 50 and 100% sorghum flour. The appearance and overall acceptability of sorghum muffins were not found to be different significantly from those of the control, up to 30% level substitution with sorghum flour.

Tempeh-type fermented products were prepared from soybean, sorghum or mixture of soybean and sorghum(1 : 1) with the traditional Indonesian inoculum(LARU : mixed cultures of Rhizopus oligosporus). Fermentation increased protein and fiber contents in the soybean tempeh(ST) and tempeh of soybean-sorghum mixture(SSM). Fat content was slightly higher in sorghum tempeh(SGT) and SSM than that of control. During the fermentation, pH, soluble solid and soluble nitrogen were increased, while no significant change was found in the total solids. The trypsin inhibitor activity(TIA) and phytic acid content decreased after 32 hrs fermentation. It is suggested that Rhizopus oligosporus is capable of hydrolyzing trypsin inhibitor and phytic acid of the substrate. Thiamine and niacin contents increased in all samples as compared with the unfermented control. In amino acid level, there were some decreased in total amino acids after 32 hrs fermentation in three types of tempeh. While the concentrations of lysine, valine. tyrosine and alanine in ST, SGT and SSM were increased those of serine and glutamic acid were decreased in compare to the unfermented control.

1972년도의 양계상황은 어떻게 될 것인가? 1972년도 종계의 적정수요선은 얼마나 되며, 1972년도 외국종계의 적정수요수수 및 실제도입 수수는 얼마나 될 것인가? 이에 따라 1973년도 양계업은 호황이 될까? 아니면 불황이 될 것인가? -요컨데 공급과 수요의 균형이 문제다. 다시한번 차분히 생각하고 생산 및 규모조절을 한다는 것은 경영합리화를 위한 한가지 수단이 될 수 있을 것이다.

This study was carried out to investigate the effect of harvest stage of Sorghum ${\times}$ Sorghum Hybrid (SSH) and manufacture methods of SSH silage on nutritive values and quality of SSH silage manufactured with SSH grown in paddy land of Department of Animal Resources Development, National Institute of Animal Science, RDA. SSH "SS405" was harvested at two different growth stages (heading and ripen stage) and ensiled at each harvest stages. The content of crude protein in both square baled SSH silage (SBSS) and bag silage (BS) increased with delayed harvest maturity, but the contents of ADF (acid detergent fiber), NDF (neutral detergent fiber) decreased. The contents of ADF and NDF was not influenced by the inoculation of lactic bacteria. The contents of TDN (total digestible nutrient) in both stage and in vitro dry matter digestibility (IVDMD) in heading stage was not influenced by the harvest stage of SSH. The pH in all SSH silage ranged from 3.8 to 4.4 at two different harvest stages, and pH in heading stage was higher than that of ripen stage (P<0.05). The content of lactic acid of all SSH silage increased with delayed harvest maturity (P<0.05), but the content of acetic acid decreased (P<0.05). The contents of lactic acid and acetic acid in ripen stage were not influenced by manufacture method of silage. The content of lactic acid in both SBSS was higher than that of both BS and RBSS in heading and ripen stage (P<0.05), but the content of acetic acid decreased (P<0.05). The contents of lactic acid and acetic acid in BS were similar as compared to that of RBSS. Therefore, we suggest that the quality of SSH silage in both heading and ripen stage can be improved by manufacture methods of SBSS and BS.

Occurrence and yield characteristics of lepidopteran insect pests in both PUR (paddy-upland rotation) and CU (continuing upland) fields for 8 maize (Eolrukchal 1, Heugjeom 2, Miheukchal, Ilmichal, Heukjinjuchal, Chalok 4, Mibaek 2, Daehakchal) and 7 sorghum (Hwanggeumchal, Anzunbaengisusu, Moktaksusu, Sodamchal, DS-202, Nampungchal, Donganme) varieties was surveyed. The population of Ostrinia furnacalis adults showed 3 times highest peaks in 2016. In addition, the damaged ratios of maize and sorghum leaves and stems were increased depending on the growth periods of the crops and those by O. furnacalis larvae were also increased steeply in mid August. The damaged ratios of maizes such as Miheukchal, Eolrukchal 1, Ilmichal, Heugjeom 2, and Mibaek 2 by O. furnacalis larvae were statistically different (P=0.05) between organically managed PUR and CU fields. Except for DS202 among sorghum varieties, the damaged ratios of the other ones were high and similar (50-92%) in the CU field. The ear damaged ratio of maize varieties by lepidopteran larvae including O. furnacalis and Helicoverpa armigera was from 5 to 38% in Chalok 4 and Heukjinjuchal, respectively, and Daehakchal gave relatively higher damage ratio in the PUR field (33%) than in the CU field (14%). The ear ratio of Sodamchal and DS-202 varieties in the PUR field was 94 and 82%, and all sorghum varieties were damaged over 78% by lepidopteran larvae in the CU field. Interestingly, the correlation coefficients between the damaged ratio and invasive pores on their stems by O. furnacalis larvae were positive (maize $r=0.69_{paddy-upland}$, $0.95_{continuing}$; sorghum $r=0.93_{paddy-upland}$, $0.97_{continuing}$, respectively). Additionally, the correlation coefficients between the damaged ratio and the ear weight or the thousand kernel weight (g) of maizes and sorghums by lepidopteran larvae were negative (maize $r=-0.38_{paddy-upland}$, $-0.49_{continuing}$; sorghum $r=-0.70_{paddy-upland}$, $-0.57_{continuing}$, respectively). These results indicate that the focused management on lepidopteran insect pests occurring maizes and sorghums cultivated in PUR and CU fields is an important strategy to secure their yields.

BACKGROUND: Sorghum (Sorghum bicolor (L.) Moench) ranks as the 6th most planted crop in the world behind wheat, rice, maize, soybean, and barley. The objective of this study was to identify bio-marker among sorghum cultivars using proteomics approach such as two-dimensional polyacrylamide gel electrophoresis (2-DE) coupled with mass spectrometry (MS). METHODS AND RESULTS: Proteins were extracted from sorghum seed, and separated by 2-DE. Total 652 spots were detected from 4 different sorghum seed after staining of 2-DE with colloidal Coomassie brilliant blue (CBB). Among them, 8 spots were differentially expressed and were identified using MALDI-TOF/TOF mass spectrometry. They were involved in RNA metabolism (spot1, spot 4), heat shock proteins (HSPs, spot 2), storage proteins (spot 3, spot 5, and spot 6), and redox related proteins (spot 8). Eight of these proteins were highly up-regulated in Whinchalsusu (WCS). The HSPs, Cupin family protein, and Globulin were specifically accumulated in WCS. The DEAD-box helicase was expressed in 3 cultivars except for WCS. Ribonuclease T2 and aldo-keto reductase were only expressed in 3 cultivars except for Daepung-susu (DPS). CONCLUSION(S): Functions of identified proteins were mainly involved in RNA metabolism, heat shock protein (HSP), and redox related protein. Thus, they may provide new insight into a better understanding of the charactreization between the cultivars of sorghum.

Until now, The experiment about the forage crop have been almost not conducted on the reclaimed land. Therefore, this experiment was carried out in order to know productivity of summer forage crop using slurry composting-biofilteration (SCB) liquid fertilizer on reclaimed land of Hwaong and Sukmoon in korea from 2008 to 2009. The forage crops used in this experiment were corn and sorghum${\times}$sorghum hybrid which are used as summer forage crops in South Korea. The experiment was treated with chemical fertilizer (CF), swine slurry (SS) and SCB liquid fertilizer. Dry matter (DM) yield of corn was higher than those of sorghum${\times}$sorghum hybrid in both reclaimed lands but the effect of SCB liquid fertilizer was not appeared. The neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents of corn were lower than those of sorghum${\times}$sorghum hybrid. The crude protein (CP) content and in vitro dry matter digestibility (IVDMD) of corn were higher than those of sorghum${\times}$sorghum hybrid. In generally feed values of corn were higher than those of sorghum${\times}$sorghum hybrid. The results of this study showed that summer forage crop cultivation using uses SCB liquid fertilizer on reclaimed land are possible.

To obtain basic information on forage sorghum F$_1$ hybrid breeding a total of 16 lines were selected from 311 introduced sorghum germplasm accessions, assessed and classified by the taxonomic distance and principal component analysis. The lines of which plant height and morphological characters were diverse and the 50% flowering date was similar to each other, were selected for parental lines in sorghum $\times$ sweet sorghum and sorghum $\times$ sudangrass crossing groups. Three varietal groups were classified by the average linkage cluster analysis based on the D$^2$ computed in eleven characters. Group I, II and III included 6 lines of sudangrass, 4 lines of sweet sorghum and 6 lines of grain sorghum, respectively. In the result of principal component analysis for eleven characters, about 82% of total variation could be appreciated by the first four principal components, the first principal component was highly loaded with head compactness and shape, l00-seed weight, plant color and grain covering, the second principal component with flowering date, plant height and awnness.
