Chromosome Morphology of Clitoria ternatea and C. biflora

Abstract

Karyomorphology of four varieties of Clitoria ternatea and one of C. biflora revealed the chromosome numbers as 2n=16 for C. ternatea and 2n=14 for C. biflora. Karyotypes were mostly symmetrical with majority of chromosomes being sutmedian. Only in C. ternatea var. Faint blue and C. biflora there was one pair of subterminal chromosomes. One pair of median chromosomes was noted in all the types except C. ternatea Blue. There was one pair of SAT chromosomes in all the five taxa, its position being V in C. ternatea and IV in C. biflora. Intraspecific variations were not so conspicuous. However, C. ternatea Faint blue appeared to be relatively more advanced among the types studied.
