Book Description
This is a reference book which describes importance, use and basic information relevant to application of heterosis breeding in tomato for yield and quality contributing traits. Tomato is a tropical day neutral plant. It is self-pollinated crop but a certain extent of cross pollination may take place. It is a warm loving crop so easily tolerate heat and drought stress. India is the second top tomato growing country after China contributed about 11% of the World tomato production. Tomato is a rich source of antioxidants (mainly lycopene and -carotene), Vitamin A, Vitamin C and minerals like Ca, P and Fe in diet. Magnitude of heterosis, combining ability effects and its variances were estimated by line x tester analysis including 30 F1 cross combinations using 13 parents after selfing. These genotypes were evaluated for growth, yield and quality contributing traits. Ratio of general combining ability (GCA) and specific combining ability (SCA) variance revealed preponderance of non- additive genetic variances for all studied traits. Present book is basically written for Vegetable Science Scholar and persons interested in tomato improvement programme."

Book Description
When trying to solicit authors for this book it became apparent that the causal factors for heterosis at the physiological and biochemical level are today almost as obscure as they were 30 years ago. Though biometrical-genetical analyses point to dispersion of complementary genes - not overdominance - as the major cause of the phenomenon, plant breeders' experience still suggests a cautious, pragmatic approach to the dominance-overdominance controversy in breeding hybrid cultivars. Thus we are faced with a striking discordance between our limited comprehension of the causal factors and mechanism of heter osis on the one hand, and the extensive agricultural practice of utiliza tion of hybrid vigor on the other. Such utilization is the result of the economic value of hybrid combinations displaying superior yields and qualities as well as stability of performance, of benefits derived in breeding programs, and of the enhanced varietal protection of proprietary rights. No comprehensive and critical analysis of the phenomenon of heterosis in economic plants has been published for the last three decades since the now classical book Heterosis, edited by J . W. Gowen (Iowa State College Press, Ames, Iowa, 1952). The present book attempts to fill the gap and to assess the status of our present knowl edge of the concept, the basis, the extent, and the application of heterosis in economic plants.

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
This book describes the strategy used for sequencing, assembling and annotating the tomato genome and presents the main characteristics of this sequence with a special focus on repeated sequences and the ancestral polyploidy events. It also includes the chloroplast and mitochondrial genomes. Tomato (Solanum lycopersicum) is a major crop plant as well as a model for fruit development, and the availability of the genome sequence has completely changed the paradigm of the species’ genetics and genomics. The book describes the numerous genetic and genomic resources available, the identified genes and quantitative trait locus (QTL) identified, as well as the strong synteny across Solanaceae species. Lastly, it discusses the consequences of the availability of a high-quality genome sequence of the cultivated species for the research community. It is a valuable resource for students and researchers interested in the genetics and genomics of tomato and Solanaceae.

Book Description
Tomato [(Solanum lycopersicum Mill.) Wetted] is one of the most important vegetable crops grown in India. However, modern cultivars of tomato have a limited genetic diversity further the demand for high yielding disease resistant hybrids is alarming. In this study an effort was made to increase genetic variability for development of ToLCV resistant high yielding varieties and hybrids by utilizing exotic tomato breeding lines. Diversity analysis of 19 exotic tomato breeding lines and popular varieties viz., Pusa Ruby (P20), Vaibhav (P21) and Arka-Vikas (P22) was made with the D2 analysis, PCA, RAPD and SRAP markers, which revealed that exotic lines are diverse from popular varieties. Nineteen exotic tomato breeding lines and cultivars viz., P20, P21 and P22 were crossed in line x tester design to assess the combining ability and heterosis. A perusal of the results indicated that P21 x PT4227A, P22 x CLN2123E, P21 x CLN2768A, P21 x CLN2777F, P21 x CLN2400B, P22 x CLN2460E, P22 x CLN2777B, P20 x CLN2498E and P20 x CLN2777F showed significant heterosis over the best check hybrid. Further these hybrids could be used to develop mapping population and breeding for hybrid development.
