Question 16

How did plant breeding techniques help north Indian farmers to develop cane with desired characters?

Answer

Plant breeding is the purposeful manipulation of plant species in order to create desired plant types that are better suited for cultivation give better yields and are disease resistant.



Conventional plant breeding has been practiced for thousands of years since the beginning of human civilisation; recorded evidence of plant breeding dates back to 9,000 to 11,000 years ago.

With the help of plant breeding, the two varieties of sugarcane i.e. Saccharum barberi [sugarcane of North India] and Saccharum officinarum [sugarcane of South India] were crossed to obtain sugarcane varieties having desirable qualities. So that a good quality sugarcane variety could be grown in North India.
