權景鶴,崔鳳鎬 충남대학교 농업과학연구소 1986 農業技術硏究報告 Vol.13 No.1
This experiment was carried out to obtain genetic information for future corn breeding. The materials used for the study were obtained from the nation wide collection of Korean local corn lines. A total of 262 lines were used for the study of morphological characters and for the classification of lines. Results obtained are summarized as follows; 1. The days to flowering of lines ranged from 57 days to 87 days. Most lines had an average of 67 days of flowering days. 2. The number of tillers of lines showed a lot of variation among lines with 49.2% of coefficient of variation. 3. The coefficients of variation computed based on the phenotypic observation or measurement of each line were 36.1%, 27.2%, 20.0%, 16.4% and 16.3% for kernel weight per ear, 100 kernel weight, ear height, plant height and ear length, respectively. 4. Ear height, ear length, ear diameter, tiller number and days to flowering were highly and positively correlation with the plant height, Kernel size, ear size, and plant height were highly correlated with 100 kernel weight and kernel weight per ear. 5. The 262 corn lines were possibly classified into four major groups by the Euclidean distance. Group Ⅰ comprised 110 lines, group Ⅱ 74 lines, group Ⅲ 66 lines and group Ⅳ 12 lines, respectively. Group Ⅰ was characterized as having early maturity, medium plant height large kernel size and large ear size. Group Ⅱ had medium maturity, short plant height, medium kernel size and small ear size. Group Ⅲ had medium maturity, medium plant height, large kernel size and medium ear size. Group Ⅳ had late maturity, long plant height, small kernel size, small ear size and many tillering. 6. The plant height showed significant difference between group Ⅰ and Ⅱ, Ⅱ and Ⅲ, and Ⅱ and Ⅳ group. No statistical differences were observed between group Ⅲ and Ⅳ. The ear size of group Ⅰ was significantly different from those of group Ⅱ, Ⅲ and Ⅳ. Also difference of ear size between group Ⅱ and Ⅲ was significant. The kernel size, 100 kernel weight and kernel weight per ear were all significantly different among all groups classified. The row number was different between group Ⅰ and Ⅱ. The row number of lines in group Ⅳ was significantly different with group Ⅰ, Ⅱ, Ⅲ respectively. The number of tillers and flowering days of linfes in group Ⅳ were greatly different from those of group Ⅰ, Ⅱ and Ⅲ. 7. The corn lines collected from northwest plain regions and middle hilly regions in Korea had medium maturity, medium plant height, large ear and large kernels. The corn lines from middle eastern hilly regions had medium size of ear kernels. The corn lines from middle southern hilly regions had late maturity, small kernel size and many tillers. The corn lines from southwest plain areas had late maturity, long plant height and many tillers.

본 시험에서는 중부이남 전역에서 수집한 재래재배종 대두 2,748 계통을 재배하여 백립중군을 분류하고 백립중군별로 특성을 조사하였다. 1. 백립중은 최소 7.3g부터 최대 48.4g까지 변이폭이 매우 컸으며, 군별 분류결과 1군(10.0g 이하)에 2.2%(60 계통), 2군(10.1-15.0g)에 14.7%(404 계통), 3군(15.1-20.0g)에 11.7%(323 계통), 4군(20.1-25.0g)에 26.2%(720 계통), 5군(25.1-30.0g)에 30.2%(829 계통), 6군(30.1-35.0g)에 10.6% (292 계통), 7군(35.1-40.0g)에 3.3%(91 계통), 8군 (40.0g 이상)에 1.1%(29 계통)가 분포되었다. 2. 백두중과 저형질과의 상관관계는 백립중과 성숙기, 결실일수와는 높은 정의 상관이었으나, 백립중과 개화기, 경장, 분지수, 절수, 협수, 도복과는 유의한 부의 상관이었다. 3. 백립중군별 평균협수는 백립중이 가벼운 1군이 66개로 가장 많았으며, 백립중이 가장 무거운 8군이 30개로 협수가 가장 적었다. The present study was conducted to evaluate agronomic characters of the soybean germplasm which was collected from the sites covering southern parts of Korean peninsula. The total collections of 2748 native soybean varieties were grouped by eight levels of seed weight and the correlation between the seed weight and the other agronomic traits were determined. Seed weight was ranged from 7. 3g to 48. 4g with a great variation and averaged 23. 5g. Seed size of the many local lines were relatively large than that of foreign varieties. Frequency distribution of the germplasm for seed weight were 2.2% in Group 1 (below 10.0g), 14.7% in Group 2 (10.1-15.0g), 11.7% in Group 3 (15.1-20.0g), 26.2% in Group 4 (20.1-25.0g), 30.2% in Group 5 (25.1-30.0g). 10.6% in Group 6 (30.1-35.0g), 3.3% in Group 7 (35.1-40.0g) and 1.1% in Group 8 (over 40.0g). There was positive correlationship between seed weight and maturity or fruiting period, while there was negative correlationship between the seed weight and the other traits such as days to flowering, plant height, and number of nodes and pods. While 100 seed weight of 464 lines (16.9% of total lines) were below 15g, and those are adequate for the bean sprouts. The fruiting period of large seeded lines was longer, however the number of pods per plant of those were less lines than that of small seeded lines.
