Twenty cultivars of pea(Pisum sativum L.) were grown in the field of Kangwon National University. They were evaluated for maturity and other characters. The relationships between values measured were analysed by the method of path coefficient. Genotypic correlation coefficients were larger than phenotypic ones. The first flowering node number, flowering time and plant height were highly correlated with maturing time. Genotypic correlation between maturing date and the first flower node number was highly significant, 0.5893 which was made up largely of a direct effect of 1.5844. A highly significant correlation was likewise obtained for the comparison between maturing date and flowering time, being influenced mainly by the indirect effect via first flower node number. The association between earliness and plant height was moderately significant.

Origin, dessemination and utilization of semi-dwarf genes of wheat were studied. Begining of wheat cultivation in Korea was about 3000 years ago and varietal name was given around in 1400 A.D. Original population carrying semi-dwarf genes was found to be Korean native Anzunbaengimil or Nanjangmil which was introduced to Jappan in the period of 1904~1905 and presumably renamed as Daruma. Genetic resemblance of these two populations was discussed. Number of pure-line selections were made from this population and Norin 10 was released in Japan by utilizing this semi-dwarf genes. Korea also released Suweon 92 and Seuseun 27 using same gene sources. Contribution of this semi-dwarf genes to the increase of world wheat production was reviewed. Semi-dwarfing genes of wheat which extended a great contribution for increasing wheat production in the world were investigated on their origin, dissemination, and utilization and the results were summarized as followings. 1. Begining of wheat cultivation in Korea was postulated to be about 3000 years ago considering the history of wheat cultivation of China and Japan. 2. Wheat varietal name was recorded as early as in 1482. However, Nongsajiksul published in 1400 has a brief description about wheat (cultural) methods. Therefore, it is not difficult to presume that varietal name was available to that time. 3. Original population where the semi-dwarf plants were selected were Anzunbaengimil or Nanjangmil which were distributed all where in Korea in the period of 1500~1941. This population had great variation in plant height, presumably a mixture with individuals carrying Rht₁, Rht₂ or Rht₁ Rht₂. 4. Dissemination of Anzunbaengimil to Japan was possiblly made during the period of Imjin Japanese Invasion to Korea, or by the Japanese Agronomists who were dispatched to Korea for investigation of agriculture and land productivity from 1901 to 1905. 5. Anzunbaengimil(Crippled wheat) may be named as Daruma(crippled wheat) after introduction to Japan or renamed as Daruma after pure-line selections were made. Considering such traits as growth habit, glume color, plant, height grain color and plant type it was concluded that Daruma is orginated from Auzunbaengimil population. 6. In Japan, semi-dwarf gene from Daruma population have been utilized extensively and released Norm 10 which became an important world wide breeding material. Seuseun 27 and Suweon 92, the Korean semi-dwarfs, were also improved using same dwarf gene source as Norin 10. 7. Dwarf genes from Daruma population, have contributed for improving several early maturing and high yielding wheat varieties in Korea such as Suweon 85, Chokwang, Suweon 215, 216, 219 and 220. 8. Norin l0/Brfvor 14 was the dwarf gene source for improving Cains and Nugains at Washington State, USA and CIMMYT semi-dwarfs. Coullee, a hard white winter wheat, was improved using Suweon 92, and Seuseun 27 was utilized for improving Tam Wheat and Holley wheats at Texas A&M, USA.

The trials were carried out for improvement of early maturing wheat varieties, desease resistant and good quality through transfering good characters of barley to the wheat, during 1980-'81. For these purpose, Chinese Spring, a wheat variety was used as male and Manker 16 a barley variety, as female parents. EACA($\varepsilon$-Amino Caprolic Acid) known as an inhibitor of blood coagulation was injected to all barley from 14 days until heading with 1$m\ell$ per culm at the level of 500ppM. $GA_3$ solution which accelerates pollen activity was also used with 75ppM concentration after pollination for two days including check to determine the single effect of EACA. Two different methods of the cross were used. One was bud-pollination, another was post-pollination. The result indicated that the post-pollination was better than bud-pollination in terms of pollination rate, even though formation rate of normal embryo was seemingly adversed. The new plant derived from barley-wheat cross was similar in phenotype to the wheat.

The magnitude of additive effects generally parralled the magnitude of difference between parental means and appeared to be more independent from non - allelic interaction than dominance effects, whereas the magnitude of dominance effects were inflated by non-allelic interaction. Additive effects were significant for all characteristics observed and those of leaf width and leaf shape index of lugs, cutter and leaf and leaf width of tips were higher than dominance effects. Non-allelic gene interaction was expressed in leaf length of lugs, cutter and tips and heterosis of these characters were lower than the other characters.

To investigate the genetic and ecological variation of culm length of wheat the different daylength has been applied to major wheat varieties planted at greenhouse in Suweon. Standard errors of culm length were larger at 12 and 8hrs day length than that of 24hrs. Variations of culm length due to different photoperiod were more remarkable in medium and short culms than that of long one. Number of genes controlling culm length of variety Robin #2 was more or less 2 genes. This study has been conducted to investigate the genetic and ecological variation of wheat calm length measured from those plants grown at greenhouse. The results are as following. 1. The calm length of the winter wheat was highest under 12hrs daylength, while that of the spring wheat was highest under 8hrs daylength. Standard errors of culm length was larger under 12 and 8hrs daylength than that of 24hrs daylength condition. 2. The culm length was shortest under the 24hrs daylength compare to under 12 or 8hrs while it was highest under 12hrs. Short and medium culm length varieties were photo insensitive but those of long culm length were photo sensitive. 3. There are many types of varietal differences for the culm length under the daylength conditions. Highest culm length group under 12 and 8hrs contition was classified. The semi-dwarf varieties that did not change their plant heights under 8 and 12hrs conditions were Hira, Yecora Resel, Sava, Sturdy, Saric 70, Sekidorisai 66 etc. 4. Varietal difference of culm elongation was noticed between 8hrs and 12hrs daylength condition. On the basis of the evidences obtained from this experiment, it may be concluded that the genetic studies related to culm length should be carried out under the most favorable conditions for calm elongation. 5. Correlation coefficients estimated between culm length and heading or maturity were negative but insignificant, but their correlations were highly significant between photo treatments. 6. Calm length of F₁ was intermediate to the range of F₂ population which seems to be distributed normally. In this regard the gene involved with calm length seemingly inherit additively. Statistical analysis for the involved genes for calm length suggested 2 genes for the semidwarf variety Robin #2 was more or less 2 genes.

This experiment was conducted to clarify the genetic nature for vernalization gene using isogenic tester lines with Vrn1, Vrn2, Vsn3 and Vrn4 respectjvely, and for lateness gene in the major Korean wheat cultivars, which are used in breeding program for early maturity. Wheat cultivars, Suweon 210, Cheonggemil and Chugoku 81 were determined to carry two dominant Vrn genes such as ; Suweon 210 had Vrn 3 and Vrn 4 ; Cheonggemil had Vrn 2 and Vrn 4 ; Chugoku 81 had Vrn1 and Vrn4, Milyang 11 had one Vrn4 gene and Geurumil did not have any Vrn gene at all. Olmil appeared to possess no-known Vrn genes so far identified but has an additional Vrn for vernalization. This new gene may be different from the known Vrn1, Vrn2, Vrn3 and Vrn4. A recessive gene for lateness (P) which is independent from Vrn genes was identified in Suweon 210, Cheonggemil, Milyang 11, Chugoku 81 and Olmil. This new gene was determined to prolong to days of flag leaf emergence which required 20-day vernalization period.

Mesophyll protoplasts derived from young leaves of Nicotiana rustica and N. tabacum cv Burley 21 were fused with the aid of polyethylene glycol(PEG). Cytological examination of protoplasts after PEG treatment revealed 12.8 % heterokaryocytes. After 7 weeks culture, the hybrid calli showing greenish white with a compact appearance were selected in contrast to parental type calli tinged with white or green color. The somatic hybrid plants were verified by morphological, biochemical and cyclological analysis. A heterosis effect for plant vigor and height was observed but the shape of leaves and flower characteristics were intermediate between N. tabacum and N. rutstica. The isozyme banding patterns for peroxidase of somatic hybrid lines were compared with the parent species. A number of isozyme bands derived from both parental species were found in the hybrids. Somatic hybrid plants have been successfully backcrossed to the parental N. tabacum particularly with somatic hybrid plants as female parents. These hybrid plants yielded small seeds, only few which were germinable.

We fabricated a-Si:H thin-film solar cell using the two-dimensional(2D) periodic patterned glass substrate. The use of a 2D periodic texture rather than a randomly texture at surface of TCO can result in higher short circuit current densities(Jsc). In order to analyze the optical effect of patterning glasses, ray-tracing simulations were performed. Also, p-i-n cells were deposited on patterning glasses as substrate by PECVD. UV-Vis spectroscopy, I-V were carried out for the optoelectronic characterization. The anti-reflective and light-trapping performance of patterning glass substrate was investigated by a comparison of experimental results with numerical simulations.
