Abstract

Plant breeding is an art, science and technology in which we can change genetic makeup of the in plants for human mankind. For improvement in plants different breeding methods can be used. On the basis of mode of pollination and propagation different breeding methods were developed. The continuous application of traditional breeding methods in a different species could lead to the narrowing of the gene pool from which cultivars are drawn, rendering crops vulnerable to biotic and abiotic stresses and hampering future progress. Several modern breeding methods are available for development of high yield varieties. At present development of hybrid varieties is a future need to increase production and feed growing population. Genetic engineering, mutation breeding and polyploidy have significant potential to improve crops.
