**7. Conclusion**

India stands second after China, in global production of fruits and vegetables but one–third of agricultural produce available for human consumption in the world per year gets wasted. Agricultural commodities after harvest are liable to decay thus, causing loss of quality and quantity Different factors are responsiple for causing post harvest losses. Ethylene as a gaseous hormone, plays an important physiological role in fruit ripening as well as accelerates the rate of aging and senescence. It also acts as a signaling molecule and controls ripening process in plants. Different transgenic approaches and breeding methods are developed in order to prevent Post harvest losses. Therefore, the significance of post harvest physiology is utmost important in the field of agriculture in developing Genetically modified crops.
