Objectives of Plant Breeding

Major Objectives of Plant Breeding Program Plant breeding is an important branch of agricultural science. Its main purpose is to develop new and improved crop varieties. These improved varieties give better yield, better quality, and better resistance against diseases and harmful environmental conditions. A plant breeding program is planned according to the needs of farmers, consumers, industries, and climate. The major objectives of plant breeding are explained below in simple paragraph form. 1. Higher Yield The first and most important objective of plant breeding is to increase crop yield.

High-yielding varieties help farmers earn more profit and improve food security. This is why yield improvement is considered the central objective of every breeding program. 2. Improved Quality Another major objective is to improve t...
