Abstract:
:Anthers of Nicotiana tabacum cultivar Wisconsin 38 were treated with the mutagen ethyl methane sulfonate and cultured to obtain populations of haploid plants of high genetic variability. The selection of these populations by their photosynthetic efficiency was carried out in a hydroponic culture chamber with a CO(2) atmosphere concentration close to the compensation point. Plants that survived 45 days of treatment were grown in pots in a greenhouse and their performance was compared to a population of unselected haploids. The growth characteristics, net photosynthesis, and chlorophyll content were measured and the haploid character verified. Selected plants were propagated by in vitro culture of buds and then diploidized to obtain seeds. Growth and other characteristics of the plants obtained were compared with those of the parental variety (Wisconsin 38) in a field assay. Growth, dry weight, leaf area, and net photosynthesis of selected plants were higher than in control plants.
