The objective of the study was to compare two cytoplasmic male sterile forms (CMS-eastii and CMS-glutinosa) with a fertile tobacco cultivar (Zamojska 4). A pot culture experiment was conducted in the greenhouse over the period from 1980 to 1982. Each pot contained 5 kg of light loamy sand. A part of the plants was given supplementary red (R) or far red (FR) light in a growth chamber. Plant height and leaf number were determined at 12-day intervals during plant growth. Leaves were picked when mature and their fresh and dry weight were measured. Harvested leaves were analyzed for the contents of nitrogen, water-soluble sugars, nicotine, carotenoids, and chlorophyll. CMS-eastii and CMS-glutinosa were found not to differ from their fertile counterpart with regard to two important characteristics, i.e. leaf number and rate of appearance of successive leaves. Small differences were found for the number of days to flower. The male sterile forms bloomed 7 days later than their fertile counterpart. Moreover, the male sterile forms and their fertile analogue differed in plant height and leaf size. The plants of cv. Zamojska 4 were taller than the male sterile plants. Cv. Zamojska 4 and CMS-glutinosa produced leaves of similar size but the leaves of CMS-eastii were distinctly smaller. The differences in plant height between the male sterile forms and their fertile analogue were somewhat larger for plants grown at red light than for those reared at natural daylight. Conversely, the largest differences in leaf size were found at natural daylight. With regard to quality, the male sterile forms were inferior to the fertile cultivar. The leaves of the male sterile plants contained more nitrogen and had a wider ratio of nitrogen to nicotine content. However, the ratio of water-soluble sugars to nicotine, being more than 10, was acceptable both in the male sterile forms and in the fertile cultivar.
