Abstract

Karyotj^e analysis of four cyprinids Cirrhinus reha (Hamilton), Amblypharyngodon mola (Hamilton), Esomus danricus (Hamilton) and Chela hacaila (Hamilton) from rivers and ponds of Orissa, India were studied. The diploid chromosome numbers in these four species were ranged from 48-52. The karyotypes were observed to be 2n=50, 10 metacentric (m) + 8 sub-metacentric (sm) + 6 sub-telocentric (st) + 26 telocentric (T) in C.re!7a;2n = 52,8m + 8sm + 36T;2n=48,12m + 12sm + 24Tand2n=52,14m + 8sm + 12st +18 in A. mola, E. danricus and C. bacaila, respectively. Species specific karyotypes were also observed among all these species. No sex chromosomies could be found in the form of heteromorphic pair. The evolutionary significance of these four karyotypes was also discussed.
