Plant Breeding by Moumita Barik Adak
Introduction Plant breeding is a scientific and artful practice that aims to improve the genetic characteristics of plants for specific desirable traits. It involves selective mating or manipulation of plants to develop new varieties with improved yield, disease resistance, better nutritional content, and other beneficial attributes. Plant breeders play a crucial role in enhancing crop productivity, ensuring food security, and adapting agriculture to changing environmental conditions.
Emasculation Emasculation is a controlled process in plant breeding that involves removing or inhibiting the development of the male reproductive organs (anthers) in a flower. This is done to prevent self-pollination and unwanted cross-pollination. By emasculating the flowers, breeders can ensure controlled pollination and crossbreeding of selected parent plants with desired traits. Emasculation is commonly used in creating hybrid varieties, where specific genetic combinations are desired for improved characteristics.
Grafting Grafting is a horticultural technique used in plant breeding to join different plant parts from two or more plants. The process involves attaching a scion (the desired plant part, often a shoot or bud) onto a rootstock (the root system of another plant). Grafting allows the combination of desirable traits from different plant varieties or species. It is commonly used to propagate fruit trees and ornamental plants, enabling the production of improved cultivars with desired fruit quality, disease resistance, and adaptation to various soil conditions.
Cutting Cutting is a method of vegetative propagation in plant breeding. It involves taking a stem or leaf from a parent plant and encouraging it to develop roots and grow into a new, genetically identical plant. This technique is particularly useful for propagating plants that do not produce viable seeds or for maintaining specific traits of a parent plant. Cuttings can be taken from both herbaceous and woody plants, making it a versatile and widely used method in horticulture and plant breeding.
