Abstract

The meiotic behavior of A. bilimbi or kamias from three geographical sites (Los Banos, Novaliches I and Novaliches II) was determined using the modified acetocarmine squash technique. All the plants from the different sites showed a diploid chromosome number of 2n=24. Abnormality observed during diakinesis was the presence of reduced bivalents (11 II=19.72%). Metaphase I was highly normal (65.34%). Abnormalities observed during this stage' were laggards (5.30%), non-congression (27.08%), and early disjunctions (4.80A). During anaphase I, although laggards were observed (21.63%), still a high normal anaphase I cells were noted (78.37%). Telophase I cells were all normal. Metaphase II and anaphase II were highly normal with a frequency of 81.53% and 83.61%, respectively. Telophase II was also normal. Pollen fertility ranged from 93.21% to 94.88%.
