Explain the advantage of cross-breeding of two species of sugarcane in India.
Sugarcane (Saccharum barberi) grown in North India, has poor sugar content and yield whereas, S. officinarum grown in South India, has thicker stems, higher content of sugar, but cannot grow in North Indian climatic conditions. The hybrid of these two species, produced by cross-breeding, has the following desirable traits:
(i) High yield
(ii) Thick stems
(iii) High sugar content
(iv) Ability to grow both in South and North Indian sugarcane fields.
