Abstract
A desynaptic clone of Sternbergia fischeriana has been recorded from Kashmir. It has a diploid chromosome count of 22, 4 long and 18 medium. Of the 11 pairs 2 are heteromorphic. Male meiosis reveals desynapsis of medium strong type. Preponderance of univalents causes irregularities in chromosome segregation resulting in genetically unbalanced gametes, only a small fraction of which are viable. Desynapsis coupled with structural heterozygosity leads to highly aberrant meiosis and results in total sterility of the clone.
