ULTRASTRUCTURAL CHARACTERIZATION OF PEARL MILLET CYTOPLASMS

Published on

The three cytoplasms of pearl millet with single nuclear genotype, L1l0 (SI), L1l0 (52) and
LllO (S3) were examined under electron microscope for ultrastructural cytoplasmic
variations. Differences among three cytoplasms were observed and it was noted that each
cytoplasm showed its structural superiority over the other two in some traits, but showed
its inferiority to others in some other ultrastructural traits. This indicated the possibility of
improvement and developing commercial lines in S2 and S3 cytoplasms with productivity
almost equal to the level of the lines, and hybrids in SI cytoplasm general1y prevalent in
India, thus, diversifying cytoplasmic base of the crop.
