A set of 21 crosses of Fl generation by diallel crosses from seven parent silkworm, Bombyx mori L. were used as materials to estimate genetic parameters such as gene action and combining ability. Experiments were conducted in 1985, and three characters, which are weight of cocoon, weight of cocoon layer and ratio of cocoon layer, were observed. The data were analyzed for each character by Jinks', Hayman's and Griffing's methods. The result obtained are summarized as folllows: 1. In Vr-Wr graphical analyses, weight of cocoon was found to be inherited in over dominance, and weight of cocoon layer and ratio of cocoon layer were observed as partial dominance. 2. Estimate of additive component of variance(D) was greater than those of dominance component of variance(H) for weight of cocoon layer and ratio of cocoon layer, and positive values of F were observed for all characters. 3. Mean squares of general combining ability were higher than those of specific combining ability. 4. Variety Jam 107 was expressed as the highest GCA effects for three characters, and high SCA effects for all characters were observed in combinations of Jam 113 X Jung 14 and Jam 107 X jung 14.

鄭元福 한국잠사학회 1989 한국잠사곤충학회지 Vol.31 No.2

This experiment was carried out to analyze genetic parameters for the selection of silkworm by diallel-crossing with three Japanese and four Chinese silkworm races. Heritability, genetic correlation and path coefficient were calculated as the statistical parameters to evaluate direct or indirect effects of various gentic characters on bave weight. The heritabilities of fifth instar period, cocoon weight, cocoon layer weight, cocon layer ratio, fibroin contents, boiling off ratio and bave weight were over 76.65% in both F1 and F2 generations. There were positive coefficients in both phenotypic and genotypic correlations between male and female of both F1 and F2 generations. The latter showed greater values in general. The correlation between bave weight and the characters of cocoon weight, cocoon layer weight,cocoon layer ratio, fibroin contents were over 0.727 in both sexes of F1 and F2. Therefore, these results suggest that above characters would be useful for genetic selection of silkworms. As result of path coefficient analysis, there was a direct effect with path coefficient value of 0.991 between bave weight and F1 female cocoon layer weight, and with the value of 0.803 between bave weight and F1 male cocoon weight. In F2, the effect showed 0,938 between bave weight and male cocoon layer ratio, and 0.930 between bave weight and male fibroin contents. The characters of cocoon weight and cocoon layer weight had greater influence on direct or indirect effects (in path coefficient) than the others.

鄭元福 東亞大學校 1984 東亞論叢 Vol.21 No.3

家蠶의 2化性 越年卵 3品種을 催靑條件에서 低溫(15±3℃)의 明·暗과 高溫(25℃)의 明·暗으로 各各 催靑하여 桑葉育한 結果를 要約하면 다음과 같다. 1. 催靑中 段階別의 蠶卵무게의 變化는 高溫과 明條件에서 무게의 感少가 많았다. 2. 幼蟲期의 眼蠶 體重은 全體的으로 보아 暗處理가 무거운 傾向이었다. 3. 全?重은 低溫과 高溫 모두 暗處理가 무겁고 또 低溫보다 高溫이 무거웠다. 4. ?層比率은 蠶118과 多寶蠶이 明處理에서 높았다. 5. 休眼卵蛾 比率에 있어서는 低溫 催靑에서 非休眼 卵蛾가 나타났으며, 蠶118과 多寶蠶은 蠶117보다 休眼率이 높았다. The bivoltine races of the silkworm, Jam 117, Jam 118 and Dabo-Jam were hatched under the condition of the long day(16 light hr and 8 dark hr) and continuous dark at low temperature(15℃)and high temperature(25℃). The larva of the bivoltine races wer reared on julberry leaves as usual. 1. The weight of eggs was decreased in long day condition and at high temperature(25℃)in batching stage. 2. The weight of molting larva tended to become heavier in continuous dark condition. 3. The single cocoon gained its weight in continuous dark condition either at high temperature(25℃)or at low temperature(15℃). 4. Coccon-layer ratio of Jam 118 and Dabo-Jam was increased in long day condition. 5. The non-dispause eggs appeared under the condition of low temperature of low temperature and diapause ratio of Jam 118 and Dabo-Jam was increased highly in contrast to Jam 117.

목화육종의 선발에 대한 유전적 parameter를 추정하기 위해 목화 7개 품종을 이면교배하여 주요 형질의 유전력과 유전상관을, 그리고 유전상관의 값을 이용하여 여러 형질이 직접 또는 간접적으로 섬유장에 미치는 영향을 구하기 위한 경로계수를 산출하였다. 친품종을 재료로 한 각 형질의 유전력은 잡종 F??세대에서 개서일수, 초장, 주당삭수, 삭중, 삭당실면중, 삭당조면중, 섬유장 등이 모두 72.71% 이상이었다. 형질상호간의 상관관계를 보면 표현형상과 유전상관의 값이 正·負間에 같은 방향이었고, 유전상관의 값이 표현형상관의 값보다 일반적으로 높았다. 섬유장과 삭당조면중의 형질상호간에는 正의 상관값을 보였다. 경로계수는 섬유장에 관여하는 직·간접효과가 삭당조면중의 영향이 컸던 것으로 평가된다. This experiment was carried out to analyze genetic parameters for the selection of upland cotton by diallel-crossing with seven strains of upland cotton. The results were as follows: 1. The heritability of seven characters were generally high. 2. The genotypic correlations between characters were generally higher than phenotypic ones. 3. The correlation between staple length and lint weight per boll were positive. 4. It was estimated from the path coefficient analysis that direct effects and indirect effects related staple length were much affected by lint weight per boll.

家蠶 F_1世代에 있어서 몇 가지 量的 形質에 대한 遺傳力 및 遺傳相關의 推定

鄭元福,張權烈,韓鏡秀,金鎭馨,柳甲道,鄭鎬永,柳秀徹 한국잠사학회 1986 한국잠사곤충학회지 Vol.28 No.2

Since the estimate of the genetic relations between characters gave us effective basic informations about the selection of good strains of silkworm, the experiment was carried out to estimate the heritability and the genotypic correlation, etc. using the 21 combinations F1's by diallel crosses of seven strains of the silkworm. As the result of this experiment some conclusions obtained were as follows; 1. The genotypic correlation is estimated highly positive in the heritability for all the 9 chcracters. 2. The correlations between all the characters are positive and the genotypic correlation is generally higher than the phenotypic one. 3. Since all the correlations between the bave length and other characters are highly positive, it can be considered that the effects of the other characters on the bave length are very important.

목화의 F₂잡종집단에 대한 유전분석

정원복 한국생명과학회 2002 생명과학회지 Vol.12 No.2

목화 특성을 고려한 4개 품종을 이면교배하여 얻은 F$_2$세대의 12개 조합을 재료로 각 형질에 대한 유전자의 분포상태 및 우성정도 등을 산출한 결과는 다음과 같다. 개서일수는 상가적 효과, 우성효과, 모본효과, 정역간의 효과에서 유의하였다. 주당삭수와 개화일수는 상가적 효과, 우성효과, 모본효과에서 유의하였고, 삭중, 삭당 실면중, 삭당 조면중, 종자수, 종자폭, 종자 100립중은 상가적 효과와 우성효과에서 유의하였으며, 종자장은 상가적 효과에서만 유의하였다. Vr-Wr graph에서 주당삭수, 삭중, 삭당 실면중, 삭당 조면중, 종자폭, 종자 100립중, 개화일수, 개서일수는 불완전 우성으로 유전되고, 삭당 종자수, 종자장은 초우성으로 유전되었다. 유전분산 성분에서 삭중, 삭당 실면중, 삭당 조면중, 삭당 종자수, 종자장, 개화일수는 상가적 효과가 우성효과보다 컸고, 주당삭수, 종자폭, 종자 100립중, 개서 일수는 우성효과가 상가적 효과보다 컸다. 협의의 유전력은 삭중, 삭당 실면중, 삭당 조면중, 개화일수, 개서일수가 43.19% 이상으로 높았고, 광의의 유전력은 주당삭수, 삭중, 삭당 실면중, 삭당 조면중, 종자장, 개화일수, 개서일수가 51.71% 이상으로 높았다. The experiment was conducted to get basic information for cotton breeding program through four-variety diallel cross population. Additive, dominant, maternal, and reciprocal effect were observed significantly for days to maturity. Based on the Vr-Wr graphical analysis, the characters, number of bolls per plant, boll weight, seed and lint weight per boll, lint weight per boll, width of seed, 100-seed weight, days to flowering, and days to maturity were found to inherit incomplete dominance, and the characters of number of bolls per plant, width of seed, number of seeds per boll, and length of seed were assumed to inherit over dominance. The component of genetic variance analysis for boll weight, seed and lint weight per boll, lint weight per boll, number of seeds per boll, length of seed, and days to flowering showed that additive effects were higher than dominant effects. The narrow-sense heritability(h$_2$N) for boll weight, seed and lint weight per boll, lint weight per boll, days to flowering, and days to maturity showed high values as more than 43.19%. The estimate of broad-sense heritability(h$_2$B) value was higher than that of h$_2$N because of the low importance of dominance effects.

정원복 東亞大學校 大學院 1999 大學院論文集 Vol.24 No.-

This study was conducted by reciprocal diallel crosses using four six-rowed barley and three two-rowed barley to observe the selective index, genetic advances and selective efficiencies from F1 hybrid. The results obtained were as follows. The heritabilities of culm length, culm diameter, awn length, length of flag leaf, leaf width, number of spikes per plant, 1000 grains weight, and number of grains per spike were over 74.93%. The selection weight of leaf width was the highest of all the characters or the combinations of all the characters. The genetic advance of the leaf width was the highest of all the characters. The relative efficiency was the highest in the combination of tiller number, length of flag leaf, leaf width, number of spikes per plant, and 1000 grains weight, when put awn length, leaf width, and 1000 grains weight as 100 percent respectively.
