- Rice is a staple food in Asia. In the 1950s, Asia faced food shortages and an impending famine. If you have relatives that lived in Asia during the ’50s and ’60s, they may tell you that due to the rice shortage, many starved and those who were lucky had to supplement their diet with other crops, such as barley. In 1962, an organization focused on research and development of rice called the International Rice Research Institute (IRRI) developed a high-yielding variety of rice by crossing the two types of rice from Indonesia and China. The result was groundbreaking. The new variety called IR8 (India Rice 8) increased its yield as much as 10 times the traditional variety of rice. By the early 1970s, many rice farmers in India, the Philippines, and Vietnam switched to cultivating IR8 rice, making these countries into major rice exporters, preventing a mass famine in Asia, and saving millions of lives. In many major Canadian cities, a GMO-free, organic diet is becoming more popular, as can…Some crop plants are modified genetically by manipulating their genes. How are they made beneficial?In most parts of the world, commercial potato crops are produced asexually by planting tubers. However, in some regions of the world, such as Southeast Asia and the Andes, some potatoes are grown from true seeds. Discuss the advantages and disadvantages of growing potatoes from true seed.
