참깨 選拔에 關한 硏究 : Ⅱ. 참깨 選拔指數의 分析과 多收性 品種 選拔 Ⅱ. Analysis of Selection Index and High-yielding Variety Selection of Sesame = Statistical Studies on Selection of Sesame Variety

국문 초록 (Abstract)

참깨의 交雜育種에 必要한 兩親의 選拔에 관한 基礎資料를 얻기 위하여 참깨品種을 國內外에서 蒐集하여 1986年에 82品種을, 1987年에는 13品種을 供試하여 참깨의 收量에 크게 影響을 미칠 것으로 期待되는 14個의 主要形質을 選擇하여 調査하고 Robinson et al의 方法으로 可能한 모든 形質을 組合시켜 選拔指數를 作成하고 選拔效率이 높은 2∼3個의 形質들을 組合시킨 選拔指數를 얻어 選拔指數別로 1990年에 供試한 참깨 品種의 供試集團에서 選拔得點이 가장 높게 評價된 品種들을 選拔한 結果를 要約하면 다음과 같다.
1. 品種集團에 관계없이 選拔指數의 評價結果 增收를 위한 選拔效率이 높은 形質들은 開花日數, 生育日數, 착삭부위장, 착삭절수, 주당삭수로 이들중 2∼3個의 形質을 組合시키는 것이 바람직하다.
2. 3個의 形質을 組合시켜 指數를 作成하면 13個 品種集團에서는 I=0.136X_1+0.051X_2+0.035X_5 (X_1=開花日數, X_2=生育日數, X_5=주당삭수), 82個 品種集團에서는 I=-14, 298X_1-3.916X_4+4,883X_5 (X_4=착삭절수)이며, 2個 形質을 組合시킬 경우 13個 品種集團에서는 I=0.148X_1+0.035X_5, 82個 品種의 集團에서는 I=-11.763X_1+4.402X_5가 選拔效率이 가장 높은 指數로 評價되었다.
3. 13個 品種集團에서 作成된 指數에 따라 選拔得點이 높게 評價된 品種들은 小林675, 水原11호, Anthalya, 산동 II, 보온1, 장수, PI 211630, 영암, 안동이였다.
4. 82個 品種集團에서 作成된 指數에 따라 選拔得點이 높게 評價된 品種들은 수원17호, Anthalya, PI 211630, 水原11號, 산동2호, 보은1호, 水原13호, 안동, 小林675호였다.
以上의 品種들의 評價結果 小林675, 水原 11號, 산동2호, Anthalya, 보은1호, PI 211630 등이 選拔有望品種으로 생각된다.

다국어 초록 (Multilingual Abstract)

To get basis data for the parent selection in cross-breeding of sesame, 82 varieties were tested in 1986 and 13 in 1987. 14 characters with great effect on yield were selected and checked. selection index was analyzed by Robinson at al's method. Selection index was made by combining 2-3 characters possessing high selection efficiency. The experiment groups of 1990 were plotted according to those selection indices in order to determine the sesame varieties whose selection score is high. The results of 1990 test are as follows :
1. Regardless of the variety, such characters as days to flowering, days to maturity, length of capsule bearing stem, number of nodes with capsule, and number of capsules per plant showed high selection efficiency, So it seems desirabel to combine 2 or 3 of these characters.
2. In 3 character combination, the index showing the highest solection efficiency in the 13 variety group was I=0.136X_1+0.051X_2+0.035X_5(X_1=days to flowering, X_2=days to maturity, X_5=number of capsules per plant) ; that in the 82 variety group was I=-14.298X_1-3.916X_4+4.883X_5 (X_4=number of nodes with capsule). In 2 character combination, that in the 13 variety group was I=0.148X_1+0.035X_5 ; that in 82 variety group was Ⅰ=-11.763X_1+4.402X_5.
3. The varieties, which obtained high selection score in the 13 variety group, were Sorim 675, Suweon 11, Anthalya, Sandong Ⅱ, Boeun Ⅰ, Changsoo, PI 211630, Youngam and Andong.
4. The varieties, which obtained high selection score in the 82 variety group, were suweon 17, Anthalya, PI 211630, Suweon 11, Sandong II, Boeun I, Suweon 13, Andong and Sorim 675.
The above results recommend as promising varieties Sorim 675, Suweon 11, Anthalya, Sandong Ⅱ, Boeun Ⅰ, and PI 211630.
