Annexure I. Genetics is the study of heredity and variation. The genes present in the nucleus and cytoplasm governs the heredity and variation. The nuclear x cytoplasmic interaction largely determines the phenotype apart from the environmental factors. Gregor Johann Mendel laid the foundation for the classical nuclear genetics. The science of organelle genetics began in 1908 with the discovery of variegation of leaf colour in 4 0 clock plant (Mirabilis Jalapa). This finding unveiled the role of chloroplast genome in heredity and variation for the first time in the world. The discovery of male sterility in flax and the possible role of mitochondrial genome in the expression of male sterility made a spectacular jump in agriculture. Knowledge of organelle genetics has paved the way for the sustained food and nutritional security through crop breeding. Our main objective in writing this text book has been to strength the knowledge of graduates and researchers in genetics and plant breeding. The quintessence of organelle genetics rests on the discovery of the presence of Deoxyribo Nucleic Acid (DNA) in chloroplasts and mitochondria. Now it is well understood that organelle genes are capable of executing both auto and hetero catalytic functions viz. replication and protein synthesis. Manipulation of the organelle genomes through conventional plant breeding has gained momentum during the 20 century. Twenty first century researches are eagerly anticipating about the impact of organelle transfer techniques in evolving high yielding lines. 168 pp.

Assessing diversity by morphometric through classical plant breeding is very much useful to study the crop evolution and to identify suitable parents for developing superior progenies. The genetically diverse parents will show high combining ability resulting in high heterosis in F1 generation and throw some useful segregants in the F2 and in later segregating generations too. Genetic diversity has been classically measured with Mahalanobis' D2 method. Diversity analysis over season and environments also gives useful information in identification of suitable parents. The consistent genetic diversity over seasons and environments would be useful in practical plant breeding. Further, genetic diversity has also being measured with molecular markers to avoid environmental interaction. The book carries useful information on genetic diversity and phenotypic stability among various field and horticultural crops for the researches who involved in crop improvement program.

Selected references and further reading. Subject index. Biotechnology is the controlled engineering of plants suing in vitro methods. As a technology it is competent to meet the challenge for the increased turnover of biomass for the energy production. The world's demand for food shelter and wood is expected to double by 2030. Hence a large scale propagation and rapid multiplication of short duration plants synthesis of novel disease resistant high yielding disease free and photosynthetically efficient plants can no doubt help to solve many of the problems. Tissue culture methods have far reaching implications for the induction of genetic variability through somatic hybridization induction of mutants and selection of disease free as well as disease resistant plants. In vitro haploid production will quicken the development of inbreds (instant) and mass multiplication of elite plants. Recent strides in plant molecular biology paved the way for the DNA mediated gene transfer. The structure of blue print of life i.e. DNA deduced by Watson and Crick (1962) and the action of certain endonucleases in making nick and scission of DNA brought out by Arber Nathan and Smith (1970's) made scientists to transfer genes across taxonomic barriers and irrespective of origin birth and dignity. From 1980 onwards large number of transgenic plants were produced both in monocots and dicots by the uptake and incorporation of foreign genome and DNA recombinations. Plant biotechnology is racing ahead in geometric proportion because unlike biotechnology of animals plants raise few social moral and legal issues. Tissue culture and genetic engineering are the most important component of biotechnology. It is envisaged that in future agricultural and forest biotechnology will complement the classical methods breeding and generate novel variabilities. It will open new vistas to enable the improved production of many agronomically important plants. There is a growing need for a simple textbook in vitro plant breeding. It is our earnest hope that this present book will meet the demand for a comprehensive textbook on tissue culture and genetic engineering for the students of both under and post graduation. 288 pp.

It is a complex character. It is controlled by the action and interaction of many independent variables. Correlation measures the relationship between any two variables. But, the causal basis of such relationship is determined by path coefficient analysis. Path coefficient analysis gives a clear cut idea about the direct and indirect effects of the independent variables towards the dependent variable. This book has been written primarily for post-graduate scholars and researchers in plant breeding and genetics. The authors have attempted to write it so simple and comprehensive manner. The special feature of the book is the collection and presentation of literature related to correlation and causation. Data have been given elaborately and have been discussed with the available literature.
