Sung Kyun Um(嚴聖均),Zhoo Hyeon Kim(金周玹) 한국육종학회 1989 한국육종학회지 Vol.21 No.4
With a purpose to increase the effect of selection in bitter gourd (Momordica charantia L.), four inbred lines were crossed each other for a diallel cross set, and grown in the green house. The characters investigated were fruit length, fruit width, fruit weight, number of fruit, thickness of fruit flesh, days to maturity(from flowering), seed length, seed width, seed weight, number of seed per fruit, ovary length, ovary width, ovary weight, peduncle length, and yield. Correlation coefficient analysis revealed that six characters i.e. fruit weight, fruit length, ovary length, peduncle length, seed width, and yield showed highly positive correlations each other. Among 15 characters, eight characters, such as ovary length, ovary width, ovary weight, seed length, seed width, seed weight, number of seed, and peduncle length, showed partial dominance in vr-wr graph analysis, but they showed different degree of dominance. Ovary length, seed length, seed width, and seed weight were controlled by additive rather than dominant effect of genes, and they had very high heritabilities in both broad and narrow sense, while in ovary weight, ovary width, and peduncle length, additive effect of genes was similar to dominant effect. Number of seed per fruit was governed by dominant rather than additive effect of genes. Heritabilities(h²N) in the narrow sense were low or moderate for number of seed, ovary width, and ovary weight, and that of peduncle length was high.

여주의 果重을 目標로 早期에 選擇할 수 있는 效果的인 方法을 檢討키 위하여 果實特性面에서 相異한 4個育成系統을 材料로 이들을 二面交雜하여 兩親과 F1組合들을 pot에 심어 溫室內에 栽値하여 相觀및 遺傳分析을 試圖하였다. 相觀分析에서 調査된 形質은 子房長등 15個 形質이었고, 이중 種子 및 子房關聯形質인 種子길이, 種子幅,種子重,種子數,子房長,種子幅,種子重,果梗長, 8個形質에 대해서는 二面交雜分析을 하였다. 收量과 相關이 매우 높은 形質들은 果長, 果重, 子房長, 果梗長(花梗長), 種子幅등 이었으며, 이들 形質들은 相互間에도 높은 相關이 있었다. 種子數를 除外한 大部分의 形質들이 遺傳子의 優性 果보다 相加的效果가 컸으며, 特히 子房長과 果梗長, ,種子幅은 매우 높은 相加的遺傳子作用에 의해 支配되, 遺傳力도 매우 높았다.

從來의 繁雜한 菊花揷木法의 改良을 目的으로 揷床에 水分保有量을 달리하는 5區를 만들어 比較試驗하였다. 1. 對照區인 볕가림 없는 보통式 揷床에서는 揷穗가 2∼3日後 全部枯損되었으나 그 外의 造作한 試驗區에 있어서는 枯損의 率이 적었다. 2. 本 實驗의 5個의 造作區에서는 個體當 草長, 發根數, 總發根長을 調査하여 그 試驗區別, 成績을 各各 分散分析한 結果 1%의 高度의 有意性이 認定되었으므로 水分保有量이 菊花揷木에 있어서 顯著한 影響을 미침을 알수 있었다. 3. 各試驗區의 平均間 有意差를 檢定하기 爲하여 Kramer의 多重檢定을 한 結果 草長, 發根數, 總發根長 모두 水分保有量이 많은 A區에서 작은 E區의 順으로 良好하며 有意差는 草長에서 A區와 E區間에 發根數에서 A區와 C,D,E區間에 總發根長에서는 A區와 D,E區間에 1%의 水準의 高度의 有意性이 認定되었다. 以上의 諸結果로 보아서 適當한 水分保有量을 確保할 수 있는 揷床을 造作함으로서 까다로운 菊花揷木法을 若干解消할 수 있는 可能性을 暗示하였다. The comparative test was performed on five cutting pots whose moisture content was respectively different, with a view to improving the conventional complicated cutting methods to nurse chrysanthemum. Five different cutting pots were made from A to E. Drainage tube was made 9 cm height from bottom in pot A, and the rest were also made 7 cm, 5 cm, 3 cm and 0 cm height from bottom in pot B,C,D and E, respectively. The results obtained are summarized as follows: 1. The control plots, when unscreened from sunlight, withered without exception in less than two or three days after implanted, but on the treated plots they promised to survive even under the unscreened condition. 11. Plant height, number of rooting-cutting, total length of rooting-cutting were examined from each of the five treated plots on the basis of individual plants. From the results by the analyses of variances as shown in table 1,3 and 5, it was recognized that highly significant differences among the treatments were observed for all characters. This enabled the author to realize that moisture content had on outstanding influence on chrysanthemum cutting nursing. III. The recorded results had been analyzed statistically by the method of Kramer's multiple range test. According to the Kramer's multiple range test in all experiments, there was not significant difference at the 1% level(p<0.01)for plant height between A plot and the other plots. On the other hand, there was not significant difference at the 5% level(p<0.05)for plant height between C plot and the other B, D plots and between D plot and E plot. For number of rooting-cutting, there was not significant difference at the 1% level between A plot and B plot and between B plot and the other C,D,E plots. And for total length of rooting-cutting, there was not significant difference at the 1% level between A plot and the other B, C plot and between B plot and the other C,D,E plots. The results were proven to be excellent in plant height, number of rooting-cutting and total lenght of rooting-cutting, told in order, from plants from the cutting pots of highly hydrous plots to those of the cutting pots of plots containing less water. The above results suggested the possibility that the conventional complicated methods of cutting chrysanthemum can be improved to some extent by using well-prepared cutting pots capable of securing a proper amount moisture.
