ABSTRACT 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.

栽培番茄与其野生近缘种间种间杂交番茄的生产和表征

摘要 番茄 (Solanum lycopersicum L.) 面临着各种产量问题，如非生物和生物胁迫。野生番茄品种是经济性状的极好来源，可以通过种内和种间杂交转移到栽培番茄中，这些性状可以抵抗各种类型的压力和品质特征。本研究描述了种间和种内杂交番茄植物的发育，并筛选了最佳杂交种。种间杂交番茄植株是通过在野生番茄物种和栽培番茄之间进行杂交而开发的。在形态性状方面，杂种F1在果实重量方面表现出来自父母双方的中间值。尽管野生亲本雄性在叶宽和叶长、每株坐果数等许多形态特征方面对杂种表现出显着影响，和果实产量。杂种F1在总可溶性固形物方面也表现出良好的性状，与野生近缘种杂交后，栽培番茄中总糖、还原糖和非还原糖均富集。野生番茄在提高杂交种番茄红素水平方面发挥了重要作用。因此，希望这项研究为番茄育种开辟新的世界基因库，最终有助于适应气候变化并提高对非生物和生物胁迫的耐受性。
