담배(Nicotiana tabacum L.) 葯培養에 依한 半數體 倍加系統의 特性
S.C. LEE(李承哲),W.S. KUM(琴完洙),J.E. JIN(陳晶義),J.D. LEE(李廷德) 한국육종학회 1982 한국육종학회지 Vol.14 No.2
The field evaluation were conducted on dihaploid progenies derived from anther culture of F₁ plants of Va115×Vam-Hicks and Vall5×SC72 (Nicotiana tabacum L.). Dihaploids showed reduced vigor and growth when compared with midparent value but had increased number of harvested leaves and total alkaloids, and later the days to flower. The range of dihaploid characters were deviated more than that of their parents. There were two unexpected genotypic correlations, that is, the genotypic correlations between yield and total alkaloids of the dihaploid progenies of two combinations used were not significantly different from zero, and days to flower and total alkaloids of the dihaploid progenies of one combination was correlated positively.

생육형이 다른 대맥품종을 혼파하였을경우 품증종에 일어나는 경합상을 구명하기 위하여 본실험을 행하였던바 그결과를 요약하면 다음과 같다. 1. 장기종인 브흥은 단간종인 수원18호 보다 경합능력이 현저히 높았으며 이러한 경향은 보비구에서 보다 배비구에서 더욱 현저 하였다. 2. 혼파했을 경우 장기종의 간장은 짧아지고 단간종의 간장은 길어 졌으며 이와 반대로 수장에 있어서 단간종은 오히려 짧아지고 장간종은 길어졌다. 3. 수수 및 일수립수는 처리간 차이가 인정되지 않았다. 4. 단파의 경우 수원18호는 보비구가 배비구보다 약간 수량이 많았고 이와 반대로 부흥은 배비구가 보비구보다 현저히 수량이 많았다. 그러나 혼파의 경우에는 전체적으로 배비구에서 보비구보다 현저한 수량의 증가를 나타내고 있다. 5. 장기종인 부흥이 단간종인 수원8호보다 현저히 경합력이 우세하였으며 이러한 경향은 시비량이 증가될수록 크게 나타난다. The experiment about the mixed sowing of two different growth type varieties of barley-Buheung and Suwon#18-has been conducted to determine the competition effect between two varieties, and its results are as follows: 1. Buheung-long stem variety-showed higher survived ratio than Suwon#18-short stem variety- and that tendency was significant under the high fertilized condition. 2. When tow varieties-Buheung and Suwon#18-were sowed together, the culm length of Buheung was shorter than the single planted Buheung and that of Suwon#18 was onger than the single planted Suwon#18, however, the panicle length showed the opposite tendency to the culm length variation. 3. The number of panicles and the number of grains did not show any differences among the treatments. 4. In case of the single sowing, Suwon#18 showed higher grain yield under the common fertilized condition but Buheung showed significantly increased grain yield under the heavy fertilized condition, however, in case of the mixed towing of two varieties, the grain yield was significantly increased in heavy fertilized plots than standard fertilization. 5. The competition power was significantly superior in Buheung to Suwon#18 and this tendency was rather definite according to the fertilizer application.

N. megalosiphon에서 유래된 세포질적 웅성불임 향초의 특성
이승철,금완수,진정의,조명조,정윤화,이정덕,Lee, S.C.,Kum, W.S.,Jin, J.E.,Joh, M.J.,Jeong, Y.H.,Lee, J.D. The Korean Society of Tobacco Science 1982 한국연초학회지 Vol.4 No.1
Cytoplasmic male- sterile Hyangchio, derived from male- sterile Burley 21 containing N. megalosiphon cycloplasm, and male- fertile Hyangchio (Korean local aromatic variety) were evaluated in replicated pot trials in green-house. Male- sterile Hyangchio was comparable to the male- fertile Hyangchio for six agronomic traits and total alkaloids content. The only significant difference was that the male- sterile Hyangchio flowered 2.3 days later than the male- fertile Hyangchio. M ale- sterile Hyangchio has increased the yield than the male- fertile Hyangchio significantly in case of non- topped.

This study was conducted to investigate the effects of topping time and degree on the characteristics of three tobacco varieties, and to establish the early topping (Button stage) method at Eumseong Experiment Station, Korea Tobacco Research Institute in 1979-1980. The results are summarized as follows; yield increased in the plots of By 104, topping at button stage and under first leaf from floral arsis. Quality was good in the plot topped at button stage and under first leaf from floral axis. Price per 10a was highest in the plot topped at button stage and under first leaf from floral axis.
