Question

Which of the following is an example of new crop?

• A. Jojoba
• B. Leucaena
• C. Guayule
• D. All of the above

Answer 1

The correct option is D All of the above

Jojoba is a native shrub of the Sonoran, Mojave and Baja California deserts of Arizona, California, and Mexico as well as the southernmost portion of the California Floristic Province. It is the sole species of the family Simmondsiaceae, placed in the order Caryophyllales. Jojoba is grown commercially for its oil, a liquid wax ester, extracted from its seed. Parthenium argentatum Gray, commonly known as the Guayule is a flowering shrub in the aster family, Asteraceae, that is native to the southwestern United States and northern Mexico. Leucaena leucocephala is a small, fast-growing mimosoid tree native to southern Mexico and northern Central America (Belize and Guatemala), but is now naturalized throughout the tropics. Common names include white leadtree, jumbay, and white popinac. So, all the three are examples of new crops. Thus, option D is correct and other options are wrong.
