Morphological and Cytological Characteristics of Five Trisomics of Sorghum vulgare Pers.¹

The objective of this study was to isolate, distinguish, and characterize the trisomics of a specific cultivar of Sorghum vulgate Pers. Five of 10 possible primary trisomics were derived from a triploid and were increased. They are as follows:

1. Small-glume trisomic — glumes yellowish and small in a flexible-branched panicle; late flowering
   
2. Stiff-branch trisomic — panicle grayish.green with stiff branches; seed brightly colored
   
3. Cone trisomic — panicle pointed at emergence, becoming cone-shaped as flowering progresses
   
4. Large-glume trisomic — panicle rather open-topped with large glumes
   
5. Bottle-brush trisomic — panicle straight-sided and white at the apex when it emerges
   

Each of these trisomics sets stone seed when crossed with other stocks and transmits the trisome chromosome with a frequency sufficient to make recovery feasible in the F₁ progeny. One can distinguish hybrid progenies if he is familiar with the characteristics of the trisomics within the parent cultivar.
