Abstract |
Coix, Sorghum and Zea are closely related plant genera in the subtribe Maydeae. Coix comprises 9-11 species with different ploidy levels (2n = 10, 20, 30, and 40). The exclusively cultivated C. lacryma-jobi L. (2n = 20) is widely used in East and Southeast Asia for food and medicinal applications. Three fertile cytotypes (2n = 10, 20, and 40) have been reported for C. aquatica Roxb. One sterile cytotype (2n = 30) closely related to C. aquatica has been recently found in Guangxi of China. This putative hybrid has been named C. aquatica HG (Hybrid Guangxi). The genome composition and the evolutionary history of C. lacryma-jobi and C. aquatica HG are largely unclear. |
