Question

Sonora' and 'Lerma Rojo' are varieties of
a. Barley
b. Sugarcane
c. Rice
d. Wheat

Answer 1

Hint: Plant breeding the technique which is utilized to produce the variety of species, it is used to done purposefully, in order to get some specific genetic and phenotypic variations, and this may be done some of the methods such as selective progeny, or controlling the pollination, or by genetic engineering, commonly done in done crops such as rice, wheat, etc.

Complete answer:
Sonora and Lerma Rojo are the varieties of dwarf species of wheat.

This species is not native to India, where they were brought from the other countries, and done the recombination and mutation and finally integrated with the Indian agriculture.

In order to produce the various varieties of wheat in India, many scientists introduce mainly five dwarf species which include Lerma Rojo Sonora 63, Sonora 64, Mayo 64, and S-227 this is the main dwarf species, along with them more than 200 varieties are introduced and done the research.

All of these varieties are very extensively tested in major wheat growing states in our country and they came to know that some species such as Sonora 64, Lerma Rojo, and some species have characteristics of dwarfism and have the capability to produce the high yield in our country.

From the above option:
- Some of the rice varieties that are cultivated in our country are mainly derived from Oryza
- Barely is also a cereal grain, which comes under the grass family and is cultivated globally.
- Sugar cane is mainly a perennial grass, which grows mainly in tropical areas, useful for sugar production.

Hence, The correct answer is option (D).

Note: Norin 10 is the semi-dwarf wheat variety originated in Japan, it mainly consists of two important genes such as Rht1 and Rht2, this gene reduces the size, and the above-given species which are Sonora 64 and Lerma Rojo are also produced from this variety.
