【正文】 chers at five universities. They have been using conventional(傳統(tǒng)的 ) breeding methods to develop and test soybeans that can grow well under dry conditions. His research has taken him as far as China, where soybeans have been grown for thousands of years. Farmers in the United States, however, have grown soybeans for only about a century. Tommy Carter says the soybeans they grow are for the most part geically similar. More differences, or diversification(多樣化 ), could better protect crops against climate changes that can reduce production. Those changes include water shortages which could increase because of global warming. The Agriculture Department has a soybean germplasm(生殖質(zhì) ) collection, a collection of geic material passed from one generation to the next. They looked at ones from the ancestral home of soybeans, Asia. They searched for germplasms that could keep plants from weakening and wilting(枯萎 ) during hot, dry summers in the United States. Tommy Carter says they found only five. But these slowwilting lines, he says, produce four to eight bushels(蒲式耳 ,容量單位 ) more than normal soybeans under drought conditions. The yield depends on location and environment. Scientists are also working on other plants that either use less water or use it better, or both. For example, panies like Monsanto, DuPont and Syngenta have been developing corn with reduced water needs. Monsanto expects to be ready in a few years to market its first corn seeds geically engineered to resist drought. 111. Which sentence is NOT true about Tommy Carter39。s most famous scientist after Albert Einstein.
