This trisomic plant and its progenies showed a typical qualitative trait of Bush, the primary trisomic for chromosome 1. The trisomics have narrow, a relatively short, dark blue-green leaves. One primary trisomic plant was obtained among the 45 plants in the selfed progeny. Genetic analysis with some multiple genetic marker stocks will provide interesting information on the genetic architecture of this particular segment and also chromosome 1 as a whole. The extra chromosome seems to consist of a complete short arm and a small segment of the long arm.
Detailed analysis is now underway.
