As scientists have developed more productive crop varieties, farmers have switched from growing many traditional varieties to new high-yield varieties. For example, in India, the 10,000 varieties of rice once grown have been reduced to 10 major ones for most of the rice crop. Why is this practice of reducing the varieties of a crop dangerous? Question options: It makes the overall crop more susceptible to pests and/or disease. It reduces the variety of crops available for human diets. it requires a larger investment than small farmers can make it could reduce or cause the extinction of some predatory insects

A. What challenges face the next Green Revolution? B. What is Marker Assisted Breeding? C. Most of the improvement in agricultural crop yields has been through inputs: getting more fertilizer to the plant, decreasing weeds, spacing, reducing loss from pests and local environmental changes. But the next big engineering feat will be with the plant molecular pathways themselves, in particular, photosynthesis. The article refers to C3 and C4 plants. What are plant geneticists trying to accomplish? D. What is the #1 seller at Wal-Mart?
Frank is a farmer who is primarily motivated to maximize yield and profit. What type of agriculture does he likely practice? Diversified Sustainable intensification Conventional Agroecological Celeste purchases maize seed one year to see if she can increase her yield. The crop looks good and so she decides to save a portion of the seed to plant the next year. The next year she plants the saved seed and is disappointed in the outcome. The crop isn’t uniform and doesn’t yield well. What type of seed was the maize that Celeste saved? Open-pollinated Hybrid Heirloom Bt A plant breeder at a university has developed a new variety of wheat through a breeding process that has taken place exclusively on university agricultural experiment land, where the soil quality is excellent and irrigation is readily available. In these conditions, this new wheat variety has experienced yield increases of up to…

Miracle RiceRice is staple food in Asia. In the 1950s, Asia faced food shortage 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 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 ground breaking. 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. 1) Is the IR8 rice variety considered a genetically modified organism (GMO)? Why or…
