This experiment was carried out to get the genetic information for increase breeding efficiency in soybean. Six soybean varieties were used as diallel-cross materials to investigate the inheritance of flowering and maturity. Incomplete dominance with large additive effect was present according to the genetic parameter of variance component for days from planting to flowering(DPF) and days from planting to maturity (DPM). The DPF was ruled by more recessive alleles and DPM by more dominant alleles. A few genes were thought to govern the DPF and DPM. By Wr/Vr graph analysis, relevant genes for DPF and DPM acted as partial dominance and the dominance order of parents was changed along with generation. Okuhara wase was dominant in DPF, while Paldalkong was recessive. Yuhsuzumi and Danyeobkong were dominant in DPM, while Okuhara wase and Paldalkong were recessive. By the generation mean analysis, all three soybean crosses revealed that additive gene effect was significantly high in both DPF and DPM. F₂ individuals in all three soybean crosses showed continuous normal distributions of DPF skewed to late parent and transgressive segregations of DPF over the early or late parent. F₂ distributions of all three crosses for DPM were also continuous ones having central peak near mid-parent with transgressive segregations mainly toward to the earlier direction over the early parent. All genotypic correlation coefficients was higher than phenotypic one and interrelationships among DPF, days from flowering to maturity(DFM) and DPM was closely associated. Broad sense heritability was fairly high for DPF(0.645) and DPM(0.678) in F₂.

Exact estimates of genotype×location interaction are of major concern to the plant breeder in developing improved varieties. This study were conducted to compare the growth characters of Korean native black soybean lines grown in Korea and Taiwan, and to examine the selectable growth characters regardless of locations. One hundred and forty Korean native black soybean genotypes were evaluated in two different locations(Taiwan and Korea) for growth and yield characters. Average DPM(days from planting to maturity) was larger in Korea(141 days) than in Taiwan(102 days), and DPF(days from planting to flowering, 24 days) was shortened more than DFM(days from flowering to maturity, 15days) in Taiwan. One hundred seed weight was not different from two locations, and seed yield was 245, 192㎏ per 10 are in Korea and Taiwan, respectively. All the growth characters were closely related to the flowering and maturity responses in Korea, whereas plant height and pod number/plant were not in Taiwan. Significant correlation between DPF and DPM was present in Korea. But in Taiwan DPF was negatively correlated with DFM. Selectable characters regardless of locations were suggested to be DFM, plant height, and 100-seed weight in which significant correlation were found between Korea and Taiwan.

This experiment was carried out to know the varietal difference of elcological variation in flowering and maturity through five times planting from April 20 to July 10 with 20-day interval for 1991-1992. Tested fifty five soybean genotypes were classified into three or four groups based on seasonal response of flowering and maturity by principal component analysis. The upper two principal components for DPF (days from planting to flowering), DPM (days from planting to maturity), and yield per plant contributed about 96, 95, 63 percent of respective total variances. Fifty-five soybean genotypes were roughly classified into four groups by the response of flowering and three groups by the response of maturity and yield per plant, respectively. The variation of DPF at different planting time in Ⅰ and Ⅱ Group was smaller than that that in Ⅲ and Ⅳ Groups, and the shortened degree of DPM along with planting time in Ⅰ group was smaller than that in Ⅱ and Ⅲ Groups. Decreasing degree of yield per plant by late planting in all groups was critical from June 20. Yuhsuzumi and Okuhara wase were seletcted for early flowering and maturity soybean materials. Jangyeobkong and Paldalkong were also picked up for medium ones, and Danyeobkong and Dogyoukong were selected for late ones.

중부지역에서 청보리 뒷그루로 만파한 사일리지 옥수수 품종의 생육 및 수량

청보리와 사료용 옥수수 작부체계에서 청보리 수확 후 만파한 사일리지 옥수수 7품종에 대하여 생육 및 수량을 적파재배와 비교하고자 2007년과 2008년 충남농업기술원에서 수행하였다. 청보리 뒷그루로 옥수수를 만파하면 생육기간의 단축과 고온기 생육으로 인하여 경직경과 이삭의 크기와 무게가 크게 감소되었다. 적파에 비하여 만파시 지상부 전체 건물중에서 잎과 줄기의 구성비율이 증가되고 암이삭의 비율이 감소되었는데, 그 정도는 품종간 차이가 있었다. 청예수량, 건물수량 및 TDN 수량은 적파에 비하여 청보리 뒷그루로 만파시 변이계수가 높았다. 적파를 대비로 할 때 만파재배시청예수량 91.8%, 건물수량 72.6%, 종실수량 51.0%, TDN 수량 68.1% 수준으로서 종실수량의 감소폭이 가장 컸고, 이로 인하여 TDN 수량이 크게 감소되었으며, 청예수량은 감소폭이 가장 적었다. 청보리 뒷그루로 만파 재배시 건물수량과 TDN 수량이 높은 품종은 강다옥으로서 다른 품종에 비하여 이삭의 크기와 무게의 감소폭이 적었다. 따라서 청보리 뒷그루로 만파하면 경엽 건물수량에 비하여 종실수량의 감소폭이 크므로 총 건물수량을 확보하기 위해서는 파종기 이동에 의하여 이삭의 크기와 무게에서 변화가 적은 품종을 선정할 필요가 있었다. Few management studies have been conducted on late planting date for corn silage in paddy field as a barley-corn forage cropping system. Experiments were conducted during 2007 and 2008 at the Chungnam Agricultural Research & Extension Services. The objectives of this study were to determine relationships between planting date and corn forage yield and to determine the best hybrid at the delayed planting after whole crop barley's harvest. The treatments consisted of 2 planting dates and 7 hybrids. Delayed planting considerately reduced stem diameter, individual ear size and weight. The ratio of dried leaf and culm in aerial plants was increased and that of ear was decreased. The coefficient of variation in fresh, dry matter (DM) and total digestible nutrients (TDN) yield was higher at delayed planting date on cropping system with whole crop barley than that of planting at optimum season. So, fresh weight was reduced by 91.8%, dry matter by 72.6%, grain yield by 51.0% and TDN yield by 68.1%. The appropriate hybrid for delayed planting after whole crop barley harvest in middle region was 'Gangdaok' as lower in the reduction of ear size and weight compared to that of planting at optimum season. Reduction in grain yield caused to decrease the DM and TDN yields. Therefore, to gain stable dry matter in silage corn by delayed planting date on cropping system with whole crop barley was necessary to select corn hybrid on the minimum reduction in ear size and weight.

Soybean seeds are one of the most improtant sources of protein and oil in the world. Recently, emphasis has been placed on the chemical composition of soybean seeds for the processing soybean foods. This study was conducted to determine the influence of location on chemical composition of 3 genotypes of soybean seeds grown at 6 locations. On the mean value, Cheju showed the highest in crude protein content whereas Mokpo was the lowest, on the other hand, Mokpo showed the highest in crude lipid content. It was suggested that environmental factors contributed greatly to seed chemical composition. On the correlation coefficient among the chemical constituents and yield, it was shown that the protein content was negatively influenced by lipid and carbohydrate content but yield was not correlated by chemical constituents. There was a positive correlation between protein content and yield, and a negative correlation between lipid content and yield, only in Cholwon. No significant effect of interaction between location and variety was found in the analysis of variance for seed crude protein and lipid content. The results show that soybean lines having high protein or lipid can be selected regardless of locations.
