Sorghum propinquum

Sorghum propinquum is a species of wild Sorghum native to most of tropical Asia, from India to Southeast Asia, southern China, Malesia and Papuasia.[2] A perennial, rhizomatous diploid with the same number of chromosomes (2n=20) as the annual, non-rhizomatous diploid Sorghum bicolor, it is being studied for its potential for sorghum crop improvement.[3] In an ancient hybridization event with S. bicolor, it gave rise to Johnson grass (S. halepense), one of the planet's worst weeds.[4]
