词汇 | hybrid |
词源 | hybrid. The offspring of a tame sow and a wild boar was called a hybrida by the Romans, and this Latin word came into English in the early 17th century to describe such ani- mal offspring. Hybrid wasn’t applied to plants until almost 200 years later. A hybrid is, strictly speaking, the offspring of a cross-fertilization between parents differing in one or more genes, and a great many, possibly the majority, of cultivated plants have resulted from either natural or artificial hybridization. |
