Inheritance In Tomato

Tomato being a classical experimental material because of its self pollinated nature easy in crossing with other varieties, large number of seeds/fruit, easily grown under varied climatic conditions and large number of mutable loci, has been given little attention towards its genetic improvement especially for quality traits. Very high degree heterosis for yield, its components and quality characters has been reported. Study of genetic diversity among the existing genetic stocks provides an opportunity for selecting the diverse parents for the hybridization. The genetics of yield, its components and quality characters are of great significance in designing and execution of appropriate breeding programme. The present manuscript was written to achieve the following objectives:- 1.To estimate the heterosis, general combining ability, specific combining ability effects of the parents and their hybrids. 2.To estimate the components of variance for various characters. 3.To study correlation and path analysis for yield, its components and quality traits.
