The title of my research is “Evaluation of determinate tomato varieties on the basis of screening and grafting.” In Pakistan average yield of tomato is very low as compared to other countries of the world. In my present work basic theme is to improve the yield of tomato in Pakistan.
There are number of reasons that are responsible for low yield of tomato in Pakistan such soil-born diseases, improper remedies against insect/pest attack & disease, water and salinity stresses and extreme weather conditions. Grafting is the best solution to overcome the above mentioned causes as it reduce the effect of soil borne pathogens (Lee et al., 2010), increase vigor (Lee et al., 2003), resistance to biotic and abiotic stresses (Lee et al., 2003) and increase fruit quality and yield (Flores et al., 2010). Commercial vegetable grafting was introduced to Europe in the 1990s by international seed companies (Kubota et al., 2008). The grafting technique is now rapidly spreading all over the world for multiple purposes, but in Pakistan grafting of tomato is not practiced.
Therefore, it is necessary to study the grafting technique under optimum condition for successful grafting. My research focus will be primarily based on the improvement of tomato quality in case of non-grafted and grafted tomato plants.
To evaluate better rootstocks and scion varieties in relation to successful grafting;
To make comparison of non-grafted and grafted plants in terms of growth and quality tomatoes.
