Ans. The main purpose of plant breeding is the genetic improvement of the crop in order to create desired plant type which are better for cultivation and to give better yields. Most of the crops are originated from domesticated varieties, but now-a-days plant breeding is carried out by using modern techniques or molecular genetic tolls.
By using this technology, we can improve the quantity and quality of food production by keeping the following steps:
Collection of variability.
⚫ Evaluation and selection of parents.
⚫ Cross hybridisation within the
selected plants. The role of plant
breeding has played an important
role in food production:
⚫ Lysine-rich maize kinds like Shakti, Rattan, Protina and others have been produced.
⚫ By mutation breeding more than 200 kinds of crop have been produced.
⚫ The quality of disease resistance in plants has been introduced by way of
plant breeding.
⚫ All sugarcane kinds are interspecific hybrids.
⚫ The plant breeding has given the improved kinds of crops like Taichung native-1 of rice and Sonora-64 of wheat.
