Plant Introduction

The process of bringing plant genetic resources from one region to another to conserve and utilize them for agricultural advancement.

Hybridization

A breeding technique where two different varieties are crossed to combine their desirable traits and create a new variety.

Marker-Assisted Selection

A modern breeding method that utilizes specific DNA markers to identify and select individuals with desirable traits.

High Throughput Phenotyping (HTP)

A modern breeding method that focuses on rapidly measuring and analyzing a large number of plant traits to select the best individuals.
