MODIFICATION OF BARLEY MUTANTS DIFFERING IN HEADING TIME BY CHANGING THE GENETIC BACKGROUND: LINE × TESTER ANALYSIS FOR YIELD AND YIELD COMPONENTS

摘要

Induced mutations play an important role in generating genetically different germplasm, since they provide unselected variability for breeders. They can change all the important characters of a crop plant in the desired direction. In the event of unwanted simultaneous changes, it has been well documented that modification is possible by changing the genetic background of the mutant. In this study, an attempt was made to modify barley mutants differing in heading date in changed genetic backgrounds, including the original parents of the mutants.
