Detailed cytogenetical studies in Cyamopsis tetragonoloba (L.) Taub. (=C. psoralioides DC.) have been carried out. Seven and fourteen have been found to be haploid and diploid number of chromosomes respectively. Karyotype has been analysed and found to be symmetrical type according to Stebbins (1958) classification.
Inversion heterozygosity in the C. tetragonoloba has been reported for the first time. Meiotic abnormalities in the form of inversion and sticky chromatin bridges, laggards, etc. have been observed at anaphase I in about 27% cases.
Pollen sterility of about 18-20% have been found to be chromosomal in nature and caused by deficiency and genic unbalance in the microspores.
