Abstract

Meiotic investigations were carried out in four different accessions of Balanites aegyptiaca (L.) Del. collected from various parts of Rajasthan, India. Chromosome associations, chiasma analysis and distinct pattern of chromosome/chromatids at anaphase I and II were studied in detail. The study revealed that all the accessions had the gametic chromosome number, except one (B. aegyptiaca BSJO-25160) that had n = 18. BSJO-25160 accession was characteristic in exhibiting chimeric nature as revealed through chromosome mosaicism, which resulted in variant chromosome number ranging from n = 9 to n = 16 in different pollen mother cells analyzed. The evolutionary implications of chromosome mosaicism/chimerism and its role in the development of anueploid series are discussed in detail.
