“…Chaturvedi and Mitra [4] reported shoot-bud induction in callus tissue of Citrus grand& by BAP, whereas Kn totally failed to do so. Similarly, in certain other woody plants, e.g., Populus [10], tS"cea [1] and tS"nus [9], BAP has been employed to induce shoot differentiation. The responses of shoot apices to different concentrations and combinations of BAP and IAA are given in Table 1.…”

“…WINTON (1970) using the same cell stock of triploid cells used by MATHES (1964) found that some shoots rooted in light while others would only produce roots in darkness. Bows (1971) reports that Turaxucum @Wde callus cultures have produced lines which differentiate either normal shoots, teratological shoots, or produce callus only.…”

Tissue culture, variation, clone plant breeding, mutagens. SUMMARY This literature review suggests a novel approach to intra-clonal plant improvement which will utilize both the natural and induced variation associated with clonally propagated plants through various in vitro and in vivo procedures. Many plants obtained in this manner will be of single-cell origin and, hence, of pure mutant type avoiding the traditional chimerism phenomena of mutation breeding studies. While such a system of plant breeding is not intended to replace conventional breeding methods for most crops, it may have special use for the plant breeder who is working with crops which are unique, highly-adapted, or in which the sexual apparatus is disturbed.

“…This has been repeatedly demonstrated (for literature see BAJAJ & BOPP, 1971), and now it is possible to obtain a whole plant (BRAUN, 1959;VASIL & HILDEBRANDT, 1965), or even a tree (WINTON, 1970) from an isolated single cell and callus tissue under aseptic conditions. This work has now been extended to naked protoplasts removed from the confines of cell walls, and plants of tobacco (TAKEBE et al, 1971;NITSCH & OHYAMA, 1971;BAJAJ, 1972;CARLSON et al, 1972)carrot (GRAMBOV et al, 1972;KAMEYA & UCHIMIYA, 1972) and Petunia (DURAND et al, 1973;FREARSON et al, 1973) have been regenerated from them.…”

During a short span of the last four years there have been exciting developments in the field of protoplast culture and somatic hybridization.Enormous interest and enthusiasm was shown by plant scientists at the 'International Colloquium on Protoplasts and Fusion of Somatic Plant Cells', and 'Third International Symposium on Yeast Protoplasts' held in 1972 at Versailles (France) and Salamanca (Spain), respectively. At present, large quantities of protoplasts can be enzymatically isolated, and when cultured they regenerate a wall and divide to give rise to a clone of homogenous callus tissue. By manipulation of nutritional and physical conditions this tissue can be induced to differentiate into both haploid and diploid plants. The protoplasts can also be induced to fuse with one another, the fused product can be cultured, and made to regenerate into a somatic or 'parasexual hybrid'. The protoplasts take up micro-and macromolecules, viruses, bacteria, and genetic materials like DNA and nuclei, and serve for the transformation and cell modification studies. Isolated chloroplasts have also been transplanted into albino protoplasts and green plants obtained.The protoplast culture work has unlimited potentialities for plant improvement. It is already being used as a novel research tool by the physiologists, virologists, molecular biologists, geneticists, and for morphogenetic studies. The work could have far-reaching implications in agricultural research as in future (1) the regeneration of somatic hybrids from fused protoplasts of sexually incompatible or distantly related plants, (2) the introduction of nitrogen-fixing bacteria and blue-green algae into non-legumes specially the cereals, (3) the induction of disease-resistance in a crop by the incorporation of a selective genome into the protoplast, (4) the induction and easy detection of mutations in haploid protoplasts, (5) the transplantation of 'foreign chloroplasts' into crop plants with inefficient photosynthetic system, (6) culture of protoplasts to raise clones for vegetative multiplication and also for genetic diversity and (7) insertion of a part or complete genome by transgenosis, cell modification, and nuclear transplantation could replace or at least help to modernize some of the conventional practices used for plant improvement. To get this gigantic task done a close collaboration between various disciplines of plant sciences is desired, and the resources pooled together to get the maximum benefits of the facilities and the talent available. A great deal of responsibility lies specially with the geneticists and plant breeders who will eventually deal with the ultimate product. These above mentioned possibilities are by no stretch of imagination meant to be any substitute for the present day plant breeding practices, but they are certainly new valuable tools which can be exploited.
