Vegetables are important constituents of our healthy diet and provide more profits to the growers. Crop improvement is the most satisfying method of increasing the productivity of any crop. Production and consumption of vegetables has expanded greatly. Improved varieties have had a main role in the increase in yield and quality of vegetable crops.
The diversity of vegetable crops is appalling and greatly contributed to increased production and consumption of vegetables world over. For improvement of crops information on origin, distribution and evolution of crop and its related species is very essential. Information on genetics and genetic resources is prerequisite to choose the appropriate breedinng strategies to fulfill the objectives. Objectives of breeding vary with region and also purpose for which the product is used i.e., for fresh market, for processing or dual purpose and how the crop is grown i.e., under protection, open field cultivation or kitchen garden etc. Depending on the objectives and genetic resources, breeding methods or procedures can be adopted and it will results in useful varieties or hybrids. Information on breeding of vegetables crops is covered in very abridged form. More number of crops covered in this book by appending and updating information on genetics, genetic resources, breeding methods/procedures and varieties developed in each of the 26 vegetable crops wherever information is available.
Origin and evolution, genetic resources, genetics of fruits, breeding methods and varieties/hybrids developed is the sequence followed in presenting the and varieties/hybrids developed is the sequence followed in presenting the information on each of the crops.
