전상근,정현배,김영채 한국임학회 1979 한국산림과학회지 Vol.43 No.1

잣나무 苗木의 生長에 미치는 光度의 影響을 알기 爲하여 잣나무 播種床에서 2年間 庇蔭網을 利用한 4水準의 人工庇蔭處理를 行한후, 苗木의 生長을 調査檢討했다. 調査된 生長의 內容은 苗丈, 地上部長, 地下部長, 直徑, 苗木의 生重量 및 乾重量, 地上部와 地下部의 生重量 및 乾重量等이었으며, T/R ratio도 求하였다. 全體的으로 볼 때 地上部長에 있어서만 庇蔭程度(相對光度差)에 따른 一定한 傾向을 찾어볼 수 없었을 뿐 其他 生長에 있어서는 相對光度가 높을수록 生長이 큰 傾向을 볼수 있었다. T/R ratio는 相對光度가 높을수록 그값이 작아졌었다.

加平地域 잣나무 次代檢定林 16年生의 樹高·根元 및 胸高直徑 生長의 變異와 相關

全尙根 慶熙大學校 1996 論文集 Vol.25 No.-

For the investigation on the variation and correlation in tree height, root-collar diameter (RCD) and diameter at breast height(DBH), twenty Korean white pine(Pinus koraiensis)families aged 16 were tested in Kapyung site. Family, block, and family×block interaction were significant sources of variances in height, RCD and DBH growth of progenies. Average height, RCD and DBH in the 20 families were 552.08±2.05㎝, 120.69±0.80㎜ and 87.02±0.59㎜, respectively. Number 20 family showed excellent growth of 640.58±9.98㎝ in mean height, 144.65±3.61㎜ in mean RCD, and 106.05±2.56㎜ in mean DBH, respectively. Highly significant correlationships were recognized between height and RCD, height and DBH, and RCD and DBH.

永同 地域 잣나무 風媒 次代 15年生의 樹高 및 直徑生長의 變異와 遺傳力 및 改良效果

全尙根,陳鉉五 慶熙大學校 1995 論文集 Vol.24 No.-

Twenty Korean white pine(Pinus koraiensis) families were tested in Youngdong site. Family, Block, and Family×Block interaction were significant sources of variance for height and diameter growth of progenies. The average height and diameter were 315.79m, 63.3mm, respectively. Heritability estimates of height growth were higher than those of diameter growth. Estimates of individual and family heritability were 0.30, 0.59 in height growth, and 0.23, 0.56 in diameter one, respectively. Correlatioship between height and diameter growth was significantly high(r=0.799). When the top 10% of individuals or families were selected, the expected genetic gains for tree height and diameter growth were higher in the combined selection and the mass selection than in another selection methods.

잣나무 風媒次代 12年生을 樹高 및 植徑生長의 遺傳力과 改良效果

全尙根 慶熙大學校 1993 論文集 Vol.22 No.-

Twenty Korean white pine(Pinus koraiensis) families were tested in 3 different regions. Family, site, and family x site interaction were significant sources of variation for height and diameter growth of progenies. The average height and diameter were 293.6cm, 64.1mm in Kapyung site, 265.05cm, 53.9mm in Kwangju site, and 174.7cm, 33.8mm in Youngdong site, respectively. Heritability estimates of height growth were higher than those of diameter growth across the sites. Estimates of family and individual tree heritability were 0.89, 0.47 in height growth, and 0.82, 0.30 in diameter one, respectively. When the top 10% of individuals of famililies were selected, the expected genetic gains for tree height and diameter were higher in the combined selecction than in another selection method. Therefore, it would be desirable to use the combined selection method for the advanced generation in Korean white pine.

잣나무의 子葉數 및 子葉長의 變異와 遺傳力에 關한 硏究

全尙根,奏雄 慶熙大學校 1990 論文集 Vol.19 No.-

This study was carried out to investigate the variation and heritability of cotyledon with 120 half-sib families of Korean White Pine sampled from 7(A-G) different plots. Family was a significant source of variation(1% level) for the number and length of cotyledons. Number of cotyledons with family ranged from 5 to 18, and averaged 11.91±0.35. The CV value and contribution rate were 13.40% and 11.25%, respectively. Family means of length of cotyledons ranged from 21.6 to 69.3mm. CV=9.51%, and averaged 47.12±0.98mm. The contribution rate of family to cotyledon length variance was 26.47%. Family within site was a significant source of variation(1% level) in both two cotyledon characteristics. Site was a significant source of variation(1% level) in the number and length of cotyledon traits, however, contribution rate was low level of 1.28%, 0.95% respectively for number and length of cotyledons. Replication has no effects in the two traits. There was no significant relationship between number and length of cotyledon. Individual tree and family heritability for cotyledon number were 0.45 and 0.72 respectively those for cotyledon length were higher(h^2_I=1.07, h^2_F=0.88) than the former trait.

全尙根 慶熙大學校 1982 論文集 Vol.11 No.-

The degree of infestation varied with the difference of density and coverage of pine tree, and then the highest degree of infestation appeared at about 2500 individuals per ha in density and 40-60% in coverage, but the degree of infestation decreased if it was lower or higher than the above range.

잣나무의 遺傳力에 關한 硏究 (Ⅳ) : 5, 6年生의 葉長, 葉幅, 鋸齒數의 遺傳力 Heritability of needle length, width, and number of serration in 5-and 6-year-old seedlings

全尙根,柳芝昊 경희대학교 부설 식량자원개발연구소 1987 硏究論文集 Vol.8 No.-

15 families of open pollinated progeny of Pinus koraierisis were investigated to estimate the heritabilities for needle length, width, and number of serration. In the needle length and width, the significant differences were found between families, and between sites, as well as recognized that the needle length and width of 6-year-old seedlings were larger than those of 5-year-old seedlings. In needle length, single tree and family heritabilities were h^(2)_(I) = 0.12, h^(2)_(F) =0.71 and h^(2)_(F)= 0.08, h^(2)_(I) = 0.71, in 5-and 6-year-old seedlings, respectively. Heritabilities for needle width were estimated as h^(2)_(I)=0. 09, h^(2)_(F)=0. 55 in 5-year-old and h^(2)_(I)=0. 02. h^(2)_(F) =0. 22 in 6-year-old seedlings. Heritabili- ties estimated for numated of serration in 5-and 6-year-old seedlings were h^(2)_(I) =0. 09 h^(2)_(F)=0. 88, and h^(2)_(I) =0. 19 h^(2)_(F) =0. 84, respectively.

全尙根 경희대학교 부설 식량자원개발연구소 1988 硏究論文集 Vol.9 No.-

Average height, diameter and seed weight of twenty two mother trees, and height and diameter growth of progeny families from the mother trees were examined, and the variations depending upon family and block for five years (from 5-year-old to 9-year-old seedlings), as well as relationships among surveyed characters were analysed in Korean white pine. The results obtained from the above were as follows; 1. Mean height and diameter of the mother trees were 18.78 ± 0.37m and 28.30 ± 0.89 ㎝respectively, and the coefficients of variation were 9.21% for the height and 14.7% for the diameter. 2. Average seed weight over the whole families was 610.9±11.9㎎, but it varied with mother tree and seed production year. The F-11 mother tree produced the heavest average seed weight of 847.2±45.0㎎ and A-15 showed the lightest average seed weight of 448.3±18.7㎎. 3. The average height and diameter of progeny families from 5-year-old to 9-year-old seedlings, and the coefficients of variation of the two characters were as following table. 표 원문을 참조하세요 4. The height and diameter growth were affected by family and block, and showed the change of exponential curve with the increase in seedling age, and the estimated growth formulas of height and diameter were Y=4.450e^(0.243)x and Y=0.249e^(0.410)x 5. The effect of family on the variance in height and diameter decreased but that of block increased linearlly with the increase in tree age. 6. No. relationships between height and diameter were found in mother trees and progeny seedlings. But relationships between height and diameter in mother trees, progeny seedlings, and among seedling ages, were significant.

The objectives of this study were to analyze variation and to estunate heritabilities for cone production of 18-year-old open-polhated progenies of Korean White Pine in three different sites. The results were summarized as follows ; 1. Family, site, block, and interactions among these factors were significant source of variance for cone production. But the effects of family × site interaction were not relahvely large as compared with other source of variance. 2. Average values were 0.85 at Kapyung site, 0.87 at Kwangju site, 0.72 at Youngdong site and 0.82 overall three sites m mean of cone number per tree, respectively. 3. Family of No. 20 showed excellent value of 0.96 in mean of cone number per tree over all sites. 4. Individual-tree and family heritabilities were estimated 0.040∼24 and 0.16∼0.69 for cone production, respectively. For overall the sites, estunate of individual-tree heritability was 0.006 and that of family was 0.349 for cone production. 5. Heritability estunates vaned with testing site, and those for family were higher than for individual-tree.
