Book Description
The esculent Lycopersicon esculentum, long thought to be poisonous, has become a major U. S. food crop and source of vitamins and minerals, thanks largely to genetic modification and new production technology Rick (1978) Tomato (Lycopersicon esculentum Mill. ) is one of the most important solana ceous vegetable crops grown worldwide under outdoor and indoor conditions. It has become an important commercial crop so far as the area, production, industrial values and its contribution to human nutrition is concerned. During the past few decades tremendous developments have contributed to the knowledge and understanding of various areas of genetics, breeding and biotechnology and voluminous literature has been generated. The purpose of preparing this monograph is to give a comprehensive up-to-date treatment to the various aspects of genetic improvement of tomato. The emphasis has been placed on cytology, classical and molecular genetics, reproductive biology, germplasm resources, hybrid seed production, use of wild taxa, selection/ breeding methods, breeding for abiotic and biotic stresses, processing and quality breeding, improvement for mechanical harvesting, and biotechnology: tissue culture, protoplast fusion, and genetic transformation. These topics are presented in 22 different chapters. However, a few aspects have been discussed in more than one chapter. For example, seed production is treated in chapters 1, 4 and 8; molecular biology/genetic engineering in chapters 3 and 22 and heterosis in chapters 8 and 16.

Book Description
Surveys of Biological Progress, Volume I is an 11-chapter text that covers the advances in some aspects of biology, including growth and development, gene, virus, hormones, and ecological studies. This book starts with an introduction to the status of biological education in school curriculum and to the nature of gene actions. The subsequent chapter deals with the salient features of tracer methods and their application in biological and biochemical studies. Considerable chapters are devoted to various topics of biological interest, including nutrition, reproduction, growth and development, virus-causing tumors, and the link between hormones and sex differentiation. These topics are followed by a discussion on the specific activities of growth hormones and their link with the phenomena of tissue growth and differentiation. The concluding chapters consider the improvement in plant breeding methods and the effect of environmental factors on vitamin C content of food plants. These chapters also review the contribution of ecological studies in delineating population issues. This book is of value to biologists, and biology teachers and students.

Book Description
Research was undertaken to develop F1 hybrids in tomato for high yield, processing qualities with resistance to root knot nematode. Total of eighty F1 hybrids were developed and studied for yield, yield contributing traits, processing qualities and resistance to root knot nematode. Twenty three hybrids were found to be resistant to root knot nematode. Among the parents, SL120 was adjudged as the best general combiner for fruit weight, yield and all the root knot nematode resistant traits. Four hybrids were found to be superior with high mean and high heterosis for yield, processing qualities and resistance to root knot nematode. SCA variance was higher than GCA variance indicating better role of non additive type of gene action, emphasizing the importance of heterosis breeding. Biochemical analysis of two important enzymes; peroxidase and polyphenol revealed that the activity of both the enzymes were more in resistant hybrid and its parents. This work has resulted in the development of four high yielding F1 hybrids with high level of resistance to root knot nematode along with processing qualities. They are CLN 2026CxSL 120, CLN 2026ExSL 120, LE 812xSL 120 and CLN 1464A x SL120.
