The influence of cytoplasms from different Nicotiana species on flue-cured tobacco (N. tabacum var. Hicks) was studied. Means of normal Hicks and CMS Hicks (4 malesterile lines) were compared for a few agronomic and chemical traits. Days to flower, plant height, and total alkaloids were significantly different at 1% level, and leaf width and yield at 5% level. Early field growth of CMS plants with different cytoplasms was slower than normal Hicks. CMS Hicks lines with these cytoplasms showed recovery of subsequent growth and no significant differences in quality of cured leaves.

Seeds of 2 tobacco varieties were irradiated with 6 dosage levels of gamma-ray rang ing, from 5 KR to 30 KR, in an attempt to induce mutations. A chemical mutagen, Ethyl Methane Sulphonate, was also used in this experiment:3 varieties, 4 levels of concentration from 0.5 to 4%, and 2 different length of treatment, 3 and 12 hours. At the dosage level of 25-30 KR, 50 % of plants died 4 weeks after germination, and those survived plants showed considerable seedling retardation of more than 50%. Sensitivity to irradiation was more profound in B.Y 104 than Hicks variety at the seedling stage. Overall reduction of plant height in the field was 10-15% compared to untreated plants. The treatment of 4% EMS for 3 hours reduced survival rate to 50 % and 2% for 3 hours caused 50% reduction in leaf length. Three varieties responded same to the various treatments, but the survival rate and leaf length decreased as the duration and concentration of EMS treatment increased.

우리나라 고추재배에 큰 문제가 되고 있는 TMV, 역병, 더뎅이병에 대한 저항성품종 육성의 처음단계로써 이 3가지 병에 대한 고추의 계통 및 품종에 대한 저항성 정도를 검정하였다. TMV에 있어서 37계통중 5개가 저항성으로 나타났고 역병의 34계통 중 4개, 더뎅이병에서는 외국 도입계통들이 저항성으로 나타났다. 이 성적은 2차년도 교배 조합을 작성할 때 도움이 될 것으로 보인다.
