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: Small‐glume trisomic — glumes yellowish and small in a flexible‐branched panicle; late flowering Stiff‐branch trisomic — panicle grayish.green with stiff branches; seed brightly colored Cone trisomic — panicle pointed at emergence, becoming cone‐shaped as flowering progresses Large‐glume trisomic — panicle rather open‐topped with large glumes Bottle‐brush trisomic — panicle straight‐sided and white at the apex when it emergesEach 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 F 1 progeny. One can distinguish hybrid progenies if he is familiar with the characteristics of the trisomics within the parent cultivar.
