Agriculturists(農(nóng)學(xué)家) believe amaranth(莧屬植物) is the most promising（有 前途的)crop to come along in the near future.It has been discovered that amaranth is a highly nutritious(有營養(yǎng)的) food.It has something that is missing in wheat(小麥) and rice.Amaranth can be made into flour and many other foods.Bread made from amaranth is heavy and very compact compared with the light and airy bread common in North America.It is true that breeding a wild plant into a major food crop such as wheat requires much research time.Agriculturists know that it has taken hundreds of years of breeding different kinds of wheat to get the kinds we have today.At present,there are several problems in growing amaranth as a crop.Because it is a wild plant,it is hard to know the date when the crop will be ready to be harvested.It is impossible to know the height of the plants or the yield of a given amount of seed.It is important to breed a plant of the same height and one that can be harvested
