  • 1. Number of accessory chromosomes in the progenies of rye which were obtained from mother plants having 2, 4, and 6 accessory chromosomes by open pollination were observed. The result was shown in the Table 1. 2. Cross between the plant with 14 ordinary chromosomes having chromsome breakage and normal plant with 14 ordinary chromosomes was carried out. A plant among the progeny of this cross was found to have two accessory chromosomes in addition to 14 ordinary chromosomes. This phenomenon may be useful to postulzte the possible origin of accessory chromosome in rye.

  • The study was carried out to analyse the relationship between the frequency of accessory chromosomes in rye and soil property, such as pH, water content, P, N, K, Mg, and Ca. It was apparant that frequency of accessory chromosomes in rye was found to be higher in acidic soil than they are in basic soil. Chromosomal aberraton including translocation hetrozygote and broken centromere were found in the meiosis in PMC. It seems to be that more translocation heterozygote occurs in the plots of Paldang and Sinjangri where pH of soil shows high pH value.

  • Rye is cultivated on about 30,000ha domestically for forage and green-manure production in Korea. 'Daegokgreen' has been developed as a good quality rye cultivar for forage and green-manure, which was doubled-chromosome by colchicine treatment of diploid rye cultivar 'Gogu' in 2010. By the colchicine treatment with 0.05% for 12 hours at $2^{nd}$ leaf stage of 'Gogu', 31 tetraploid plants were obtained and they produced 2,470 seeds with 135 spikes. There was 4.4 in the number of spikes per plant, 18.3 in grain number per spike, and 37.6 g in the1,000-grain weight. The heading date of 'Daegokgreen' was April 11, which was two days later on average compared with 'Gogu'. The biomass (fresh weight) of 'Daegokgreen' was 3,701kg, which was similar to 'Gogu'. The average crude protein content of 'Daegokgreen' was 8.9%, which was 1.0% point higher than 'Gogu'. 'Daegokgreen' was found to be strong resistant to winter-kill and can be adapted to before maize cultivation.

  • Cover cropping and liquid manure application are considered as effective ways to replace the use of chemical fertilizer in orchard. This study was conducted to investigate the effect of cover crop species and liquid manure application rate on green manure production, leaf mineral content, fruit quality and soil chemical properties in pear orchard. The treatments include rye and hairy vetch as cover crops, two liquid manure application levels based on N and $K_2O$ requirement on each cover crop species, and chemical fertilizer as control. Green manure production was higher in hairy vetch than in rye. K content of pear leaves and soil exchangeable K content increased in N based liquid manure application treatments. The yield was higher in rye + liquid manure and fertilizer treatments, and fruit quality was not different between the treatments. Taking all of these into account, rye + $K_2O$ requirement-based liquid manure application is recommended in pear orchard for not only sufficient nutrient supply but also prevention of any problem related with soil $K_2O$ accumulation in pear orchard in long-term perspective.

  • This study was conducted to evaluate the effects of crop rotation on the weed occurrence in green onion and red pepper cultivation. Rye and hairy vetch were annually seeded for winter season. The reduction of weed germination was pronounced by about 50% in green onion field, but was not significant in red pepper field through rye cropping. Among weed species, the germination of Abutilon theophrasti, Cyperus iria and Digitaria ciliaris was distinctly inhibited by exudate of rye root, but not by that of hairy vetch in vitro experiment. The return of rye biomass into onion field decreased amount of weed biomass but increased index of weed diversity.

  • This study was conducted to increase the utility and productivity of forage crops at high altitued areas. For that purpose, 21 cultivars of corn and 2 cultivars of rye were cultivated for 3 years using a randomized block designed with 3 replications. The results obtained were as follows. 1. In the Taekwallyong area (800m above sea level) which has a short frostless period, all the seeding and harvest of corn must be finished within about 135 days between mid May, the time of the last frost, and late September, the time of the first frost 2. It was relatively safe for the early maturity cultivar(ll0days) and the medium maturity cultivar(l20days), compared to the late maturity cultivar(l30days) which might have had the possibility of an overlapping period between the time of harvest and the first frost in high altitude areas 3. The productivity of forage corn, which is the most efficient crop for capturing solar energy, varied significantly with the climate circumstances but the productivity of Taekwallyong showed similar results of 19 M/T/ha, compared with 20 M/T/ha in Suwon from the '96-'98 study 4. Rye could be cultivated in high altitude areas and when corn was raised as a second crop after rye in the same year, it was possible to increase the productivity of dry matter yield by 20% through double cropping(P < 0.05).

  • This study is aimed to analyze the effect of lactic acid bacteria inoculants (LAB) on quality of rye silage fermentation, harvested at early heading stage. The nutritive values were similar between the control and LAB inoculated silages. The pH of rye silage in LAB inoculation significantly decreased as compared to control (p<0.05). In addition, the content of lactic acid in LAB inoculation significantly increased (p<0.05), but the content of acetic acid in LAB treatments decreased. In addition, lactic acid bacterial counts in LAB inoculation significantly increased as compared to control (p<0.05). Therefore, we suggest that rye silage could be improved by novel lactic acid inoculation.

  • Cytological observations were carried out to investigate the frequencies and geographical distribution of accessory chromosomes in rye in Korea. (1) All the 41 strains of rye investigated were found to have accessory chromosomes and the frequencies of accessories are ranged from 2 to 73.3%. (2) The frequency ranging from 30 to 40% was predominant and it included 13 different strains. (3) The edaphic factor seemed to play more marked role than the climatic factor in determining geographical distribution of accessories in rye in Korea. (4) Breakages of A-chromosomes into two fragments were observed in 11 plants. This phenomenon may throw some light on possible orgin of accessory chromosomes in rye.

  • TO select the most suitable crop and variety of forage for nutrient quality at the southern part of Korea, the crop of wheat, barley and rye were grown from Oct. 1999 to June 2000. Paldanghomil variety of rye crop was shown to have the highest chemical components in comparison to other varieties of crops used in this experiment. It showed relatively high content of crude protein and in vitro dry matter digestibility (IVDMD) and low content of NDF, ADF, cellulose and lignin. Therefore, it was concluded that paldanghomil of rye crop was the most suitable variety with high weight and high nutrient quality for forage in the southern part of Korea. The heritabilities of all nutrient quality characters were estimated to be high.

  • Our ancestors had done their best for the moral training and home management, further more for the governing a country through observing the decorums. The 4 main decorums, i. e. the Coming-of-Age Ceremony, Wedding Ceremony, Funeral Rites and the Ancestor worship Ceremony during the Chosun Dynasty had guided well our ancestors'life harmoiously. The Wedding Ceremonies of them was one of the most happy events in their lives meaningful of the filial piety and the union of two families. The Wedding ceremonies consist of the 6 etiquetes, i. e., Eui-Hon (matchmaking), N뮤-Chae (present), Nab-Pye(bride's presents to her parents-in-law), Chung-Gi(ask the other part about an auspicious day), Moon-Myung(choice of an auspicious day), Chin-Young(take and meet a bride) in order of sequence. Chin-Young consists of Cho-Hon, Sa-Dang-Go-Woo, Sung-Bok, Cho-Rye, Boo-Myung-Ji & Mo-Song, Jun-An-Rye, Hab-Geun-Rye, Sin-Bang-Chi-Reu-Gi, Hyun-Goo-Rye, Myo-Hyun and Jae-Haeng ete, considerably complicated programs in order.
