This study was carried out at the Crop Experiment Station, Rural Development Administration, Suwon, Korea in 1990. F₁ and F₂ generations from crosses between four determinate soybean cultivars of male parents(Hwangkeumkong, Jangyeobkong, Paldalkong and Suwon 148) and two indeterminate soybean cultivars of female parents(Clark and L63-2404) were used as materials to study on the inheritance of growth characters and yield components. Heritability estimate for days to maturity was fairly high. Stem height, number of nodes on mainstem and mainstem dependence rate of number of nodes and pods had relatively high heritabilities. The heritability of branch-related and yield-related characters was low. Genotypic and phenotypic correlations were significantly positive between seed weight per plant and most of growth or yield components except 100-seed weight. But highly negative correlations were existed between seed weight per plant and mainstem dependence rate of number of nodes and pods. Path corefficient analysis revealed that number of seeds per plant had the greatest direct effect on seed weight per plant, while the total number of nodes per plant and number of nodes on branches showed the greatest direct effects on the number of seeds poer plant.

This study was conducted to study on the inheritance of growth characters and yield components at the Crop Experiment Station, Rural Development Administration, Suwon, Korea in 1990. Some quantitative characters in F₁ and F₂ of crosses between four determinate soybean cultivars as male parents(Hwangkeumkong, Jangyeobkong, Paldalkong and Suwon 148) and two indeterminate soybean cultivars as female parents(Clark and L63-2404) were investigated and analyzed for combining ability. In F₁ general combining ability(GCA) of male parents indicating principal contribution of additive genetic effects was significant in stem height, number of nodes on mainstem, number of branches, number of nodes per plant, and mainstem dependence rate of number of nodes. GCA of male and female as well as specific combining ability(SCA) was significant in days to maturity, suggesting that additive and non-additive genetic effects of male and female act simultaneously. Both GCA and SCA effects were not significant in yield components. In F₂, both GCA of male and SCA effects were significant in stem height, number of nodes, number of pods, mainstem dependence rate, and grain weight per plant. GCA effect of male was significant in number of branhces. GCA effects of both male and female were significant in days to maturity and 100 seed weight. Non-additive genetic effects were shown in number of pods on mainstem, number of pods per plant and number of grains per plant. The significance and directions of GCA and SCA effects varied according to males and females, generations and relevant characters. According to the estimated GCA, Clark and Deogyukong were found to be desirable parents for greater vegetative growth and yield, whereas Suwon 148 for earlyness, Hwangkeumkong for large seed size, and Paldalkong for high mainstem dependence rate and short stem. The estimated SCA effect for yield and lateness was great in the crosses of L63-2404×Dogyukong and Clark×Suwon 148, while SCA effect for earlyness was large in L63-2404×Suwon 148 and Clark×Dogyukong.

Soybean grain is most widely used and soybean crop produces most high protein per area among crops. To meet rapid increase of human population and supply protein in safety. soybean has considered more and more important crop. And it has been emphasizing that high quality and high protein soybean breeding must be made efforts in future. Many papers related to soybean breeding for high quality and protein and soybean protein composition have suggested the problems to do in future. Soybean germplasm collection. classification and conservation should be continuously performed, and it is emphasized that wild type of soybeans (G. soja) be considered to use in breeding for high protein varieties. Selections would be better emphasized in first yield and therefore high yield of protein per area. Selection for high protein would be secondary criterion. High protein lines with high yielding potential could be selection from certain populations, and breeders should consider this phenomenon in procedure of selection. Heritability of protein percent is relatively high and genetic gain of increment of protein percent is large. Soybean protein which is comprised 70 to 90% of globulin is constituted mostly 11S and 7S proteins. Sulfur-containing amino acids, methionine and cysteine, are identified to contain more in 11S protein than 7S protein. High 11S germplasm should be desirable to use in crossing plan, and selection of high ratio of 11S/7S lines be better in development of high quality varieties.

Nature of gene action and inheritance of the days to flower in mungbean (Vigna γ-adiata (L.) Wilczek) were determined in the F₁ and F₂ generations of 30 possible combinations of six-parent diallel cross. All the F₁ populations were grown in the pots(1/5,000a) under three different day length conditions (natural, 9-hour and 16-hour photoperiods). The F₂ populations were grown under two different plantings, early and late, in the experimental field of Crop Experiment Station, Suweon, Korea in 1984. The analysis of degree of dominance on the days to flower showed partial-to over-dominance, but the direction of dominance varied with different cross combinations. Early flowering in F₁ generation appeared to over-dominance over the late flowering under 9-hour photoperiod with no general tendency under natural and 16-hour photoperiod. Combining ability analysis indicated that both additive and non-additive gene action were involved in the days to flower. The estimation of broad sense heritability was considerably high for the days to flower (78.3%). The heritability estimates and F₂ distribution suggested that the photo-sensitive factor of V1094, which is photo-insensitive genotype was not expressed due to recessive inhibitor factor.

One of the severest endemic soybean diseases especially to soybean varieties resistant to mosaic disease in Korea is the necrotic soybean disease caused by the necrotic strain of soybean mosaic virus(SMV-N). To establish a reliable screening method for the disease, a series of experiments were carried out at the Crop Experiment Station, Rural Development Administration, Suwon, Korea for five years from 1979 to 1984. Soybean cv. Wayne appeared to be a good source of the strain SMV-N propagation since Wayne produced severe mosaic symptoms by infection with SMV-N. Only 11 soybean varieties which were all susceptible to SMV out of 48 tested were found to carry the seed-borne SMV-N. The range for the seed-born SMV rate of 48 tested soybean varieties was 0-64%. For practical screening of breeding line in the field, planting soybean varieties producing mosaic symptoms and transmissible of SMV-N around soybean lines to be tested was found to be very effective.

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.

The host affinity and interaction between soybean variety and nodule bacteria strain including R-214, USDA110, and A-1017H⁺ selected as high N-fixing strain in Korea, America and Japan, respectively were examined. The host specificity of nodule strains and various degrees of host affinities between soybean varieties and nodule strains were very high for R-241 with Hwangkeumkong, Jangyeobkong, Union, and Toyosuzu, etc.: very low for R-214 with A-1017H⁺ and IAC-2 and Peking soybean varieties introduced from Brazil and China. High affinity for USDA110 with Jangyeobkong, Hwangkeumkong, Kwangkyo, Williams82, Nambushirome was detected. In general, R-214 originated in Korea showed high host affinity with most of soybean varieties tested. USDA110 known having broad host affinity in America showed a quite good affinity with all soybean varieties. On the contrary, A-1017H⁺ known as a good nodule strain in Japan showed very low host affinity with soybean varieties presented variable response with soybean varieties.

Germination and seedling elongation of soybeans(cults : ‘Essex’ and ‘Williams’), and sunflowers cults. ‘Seed Tec’ 327 and ‘SIGCO 449’) were measured at three temperatures(15.0, 22.5, and 30.0 C) and four soil water potentials(-1.80, -0.50, -0.04, and 0.02 MPa), with and without treatment with super slurper. Measurements were made at 0, 1, 2, 4, and 8 days. Seedling moisture uptake and seedling development were affected by temperature, soil water potential, and cultivar of each of the two species. Super slurper did not significantly affect seedling growth. Highly significant positive correlations were found between seedling moisture content and seedling length. Negative correlations were found between seedling dry weight and the other dependent variables. Multiple regression equations for seedling moisture content of two species were developed as a function of cultivar, temperature, soil water potential, and interaction terms in germination time. Soybeans required more time to achieve the initial one cm of seedling length than sunflowers at the lower soil water potential(-1.80 MPa), but less time at the high soil water potential(-0.02 MPa).

Crossability of interspecific hybridization in genus Vigna was measured in all possible combinations between adzuki bean and mung bean as female parents and mung bean, adzuki bean, black gram, rice bean and V.glabrescens as male parents. Incompatibility was found in interspecific hybrids when adzuki bean was crossed as female parent. Immature embryo culture derived from hybrids of adzuki bean×black gram and adzuki bean×V.glabrescens failed to regenerate plants, whereas regenerated plants of adzuki bean×rice bean and adzuki bean×mung bean were completely died at seedling stage after transferring. Some seedling were obtained through embryo culture of mung bean×adzuki bean or mung bean×V.glabrescens, but they were not survived at all. F₁ hybrids were flowering well but sterile in mung bean×rice bean and V.glabrescens×mung bean. Even though mung bean was fairly compatible with black gram, embryo culture was the only way to obtain hybrids. Hybrids were partially fertile and flowering well, but their pod set was low. Normal pollen germination and pollen tube growth were observed in all hybridizations among Vigna species. Mostly, pollen tubes reached ovules within 24 hours after pollination.
