Question

Which is the most common method of obtaining improved variety of crops? Explain briefly.

Answer 1

The most common method of obtaining variety of crops is grafting (hybridisation).(i.e. interbreeding of two different plants to obtain plant with required characteristics). For example: A farmer grows two varieties of rice, one which produces nutritionally-rich grains during the monsoon season and the other which produces nutritionally-poor grains in all seasons. Through hybridisation of both the varieties, a hybrid plant is obtained. Therefore, a hybrid plant formed will have characteristics from both the parent plants. Hence, it will be able to produce nutritionally-rich grains, which can be cultivated throughout the year.
