Production and characterisation of tomato derived from interspecific hybridisation between cultivated tomato and its wild relatives

Tomato (Solanum lycopersicum L.) is facing various problems of yield such as abiotic and biotic stresses. The wild tomato species are excellent source of economical traits which resistant to various types of stress and quality characters that can be transferred into cultivated tomato through intra and interspecific hybridisation. This study describes the development of inter and intraspecific hybrid tomato plants and screens the best hybrids. The interspecific hybrid tomato plants were developed by making a cross between wild tomato species and cultivated tomato. In the morphological traits, hybrids F1 showed intermediate values from both of their parents in fruit weight. Although wild parent male showed dominant impact in hybrids for many morphological characters such as leaf width and length, number of fruit set per truss, and fruit yield. The hybrids F1 also showed good characters in total soluble solids, total sugar, reducing and non-reducing sugar were enriched in cultivated tomato after crossing with wild relatives. The wild tomato has play important role in increased the lycopene level in hybrids. So, the hope that this study opens the new world gene pool for tomato breeding, ultimately contributing to the adapted of climate change and increase the tolerance to abiotic and biotic stress.
