BREEDING EXPERIMENTS ON MEDICINAL PLANTS. 26. THE HEREDITARY CHARACTERISTICS OF THE R1705 MUTANT OF DATURA STRAMONIUM L, VAR. GODRONII DANERT (in German)
Examination of hereditary characteristics of the R 1705 mutant produced by x irradiation showed that, from mutants with reduced growth and low alkaloid content, alkaloid alkaloid-rich plants can be cultivated by crossing with the parent strain (RK 11). The mutant proved to be of recessive character. The F/ sub 1/ generation had the characteristic s of the original plant, while in the F/ sub 2/ generation there was a 1: 3 split, according to the rules of monohybrid splitting. In the F/sub 2/ generation the radiation-altered characteristics of mutant R 1705 collectively act as a single factor difference. The size of the plant, number of leaves and fruit, as well as the alkaloid content, of the parental, F/sub 1/, and F/sub 2/ generations have been determined. The F/sub 1/ generation showed strong positive heteroesis regarding plant size and alkaloid production. The number of leaves was greater than thnt of the parental plant. The water content of the fresh leaves of F/sub 1/ was 82.9% as compared with 80.5% of the dominant and 83.9% of the recessive parental plant. The percentage alkaloid content, as well as the total alkaloid content of leaves per plant and per soil surface, is also significantly higher than that of the control plant. Along with the approximately 70% higher alkaloid production and fresh leaf weight per plant, the fresh weight of roots also increased by approximately 30%. (BBB)
