Morphological and Cytological Characteristics of Five Trisomics of Sorghum vulgare Pers.1
- K. F. Schertz2
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 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.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
