Abstract
Five 2x haploid plants derived from three different tetraploid Mediaago sativa L. plants all had normal pachytene pairing, and their karyotypes were very similar to that of diploid M. sativa. A hybrid of one 2x haploid with diploid M. falcata L. also had a normal karyotype. The pachytene chromosome lengths of the 2x haploids were shorter than those of diploid M. sativa and M. falcata but close to values for tetraploid M. sativa and autotetraploid M. falcata. The results presented support an autotetraploid origin of the parental tetraploid alfalfa.
