Epidemic necrotic soybean mosaic virus(SMV-N) was observed on the early planted soybean fields of Kyungbuk Provinical Rural Development Administration in the southern part of Korea where no record of severe SMV-N was made hitherto. Milyangkong which is successfully being cultivated without any SMV-N infection on farmer’s fields in the normal planting date of June 20 showed 88.7%, 38.9%, 25.8%, and 10.4% of SMV-N infection rates in the early planting dates of April 15, April 30, May 15, and May 30, respectively. A great deal of difference in infection rates of SMV-N among twenty tested soybean vareties as well as among three planting times, April 20, May 20, and June 20, were recognized. At the same time, high negative correlations between the infection rate of soybean mosaic virus(SMV) at flowering and that of SMV-N at maturity were also recognized at all three planting times. All American soybean varieties having indeterminated growth habits and some of Korean varieties such as Jangbaekkong, Namhaekong, Danwonking, and Eunhakong which are somewhat suceptible to SMV showed high resistance to SMV-N. Two Korean varities, Paldalkong and SS77053 were resistant to SMV and SMV-N simultaneously. Applying of the cross protection theorem is advisable in the development of soybean varieties for the upland-paddy field rotation croppings, which can be a means of avoiding the deveatating yield loss by possible epidemic SMV-N.

This study was carried out to investigate the possibility of the use of immunosuppressive agents(ISA) which are commonly used for the elimination of immune system during the organ or tissue transfer in the fields of human medical science for the elimination of post-fertilization barrier which is one of the main obstacles in the inter-subgeneric or inter-specific hybridization of soybeans. Some of the results obtained are summerized as follows ; Even with dried seeds in pod shell, the successful seed germination into complete plants by the conventional filter paper method was possible for the seeds of 25 days after flowering for regular seeds. But, in case of the hybrid seeds of G. max×G. tomentella, the seed development was completely ceased within 20 days after crossing. Considering the development of G. max seeds, it was inferred that the development of hybrid seeds was ceased much prior to they have normal germinability. Some varietal difference in the crossability of G. max with G. tomentella was recognized but high degree of crossability of G. max with four-types of chromosome number in G. tomentella, of which diploid chromosome number are 38, 40, 78 and 80, was possible. All ISA tested in this experiments showed a fairly good effects to prolong the days to hybrid-pod abscission up to 20 days after hybridization. Cytrabine, procarbazine(N-methylhydrazine) and mitomycine C were approved to maintain the pod-shell development up to 60 days after the cross. But the ovule development was seemed to be continued only up to 40 days after cross even with the ISA treatment. No significant dosage effects on the hybrid pod abscission was observed but the optimum dosage measured at 65 days after the cross was 4,000 ppm, 20 ppm and 100 ppm for cytarabine, mitomycine C, and procarbazine, respectively.

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.

콩 雄性不稔集團에 있어서 花粉媒介忠 총채벌레의 發生消長과 選好性 關聯 形質

This study was conducted to be prepared for the commercial production of hybrid(F₁) soybean seeds by either developing the practical cytoplasmic male-sterility or gametocides. Number of pods of male-strile plant were about a half of those of fertile plant, 40 pods per plant, equivalent to 800㎏ of seed yield per hectare. The inhabitaiton density of thrips(Podothrips graminum) which was the only insect that inhabited in the flower was the highest from the end of July to the early of August in Taegu area and decreased thereafter. So it is inferred that the flowering of male sterile population for hybrid seed production should be adjusted to this period. Mean number of thrip per flower showed no significant difference between the fertile and the male-sterile plants in the male-sterile population, but a great deal of varietal differnece in the number of thrips was found ; the higest inhabitatiion density was found in Jangkyungkong, Hwangkeumkong and Jangyeobkong and followed by Williams, Williams 79, L71-9120, Union and L62-5366. Soybean varieties showed the lowest inhabitation density were Jangbaekkong, Baegunkong, Paldalkong and Baekcheon. No preferencial difference in the inhabitation density of thrips for the growth habits, flower color and nectar contents of soybeans was seen but high positive correlation was recognized between the 100 seed weight or flower size and the inhabitation densety. Therefore, it is advisable to develop the malesterile population towards having plants of large seeded and to use large seeded pollen parent, at the same time, when hybrid seeds are produced.

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.
