Abstract

ABSTRACT JOSON, MARIBEL TOBIAS. 1990. University of the Philippines at Los Banos. Cytology of Clitoria ternatea L. (family Fabaceae).

Adviser: Dr. Dolores A. Ramirez

The chromosome number of Clitoria ternatea L. Acc. 4 is 2n=16. Pseudo-chromosome rings were observed in a few cells. Abnormalities were seen during metaphase I and II and anaphase I like laggards, non-congression, early disjunction of a bivalent and late disjunction of a bivalent. Anaphase II and telophase I and II were found to be normal. Analyses of pachytene chromosome showed that chromosome 1, 3, 4, 5, 6 and 8 are metacentric, while chromosome 2 and 7 are submetacentric or acrocentric. Their lengths range from 19.1 to 68.2 microns. The high frequency of bivalent formation during diakinesis and the highly normal chromosome behavior during the later meiotic stages favor the production of fertile gametes in C. ternatea. Pollen fertility ranging from 93.88 7. to 97.94% was observed.
