MUTATION BREEDING IN TOBACCO (NICOTIANA TABACUM L.) FOR BLUE MOULD (PERONOSPORA TABACINA) RESISTANCE

摘要

These results indicated that mutation breeding can be used to improve the quantitative and qualitative characteristics of tobacco. The mutation breeding programme showed that some traits in the Bursa-18000 tobacco variety can be improved, since the selected mutants were characterized by blue mould resistance. In addition, some other morphological and agronomic traits were improved, including a higher yield per unit area, a higher plant height, a higher number of leaves per plant and a higher sugar content.
