The germplasm is evaluated for selection of parent plants with desired characteristics. You will work with real seed companies, analyse their breeding programs, and present advisory reports in final presentations. Plant breeding is done to-Increase crop yield. The use of herbicides and pesticides controls weeds or kills insects, and prevents diseases, which also results in higher productivity. This helps to preserve the original traits. Strike a Balance Between Speed, Cost and Quality. Increase tolerance to environmental stresses. Plant breeders apply biotechnology and molecular breeding strategies to improve the overall function of various plants and crop systems. Plant breeding - Plant breeding - Hybrid varieties: The development of hybrid varieties differs from hybridization in that no attempt is made to produce a pure-breeding population; only the F1 hybrid plants are sought. Made with ♡ by Sagar Aryal. January 7, 2021 – Most plant-based foods we eat today are a product of innovative plant breeding … Higher quality varieties are essential for a successful plant breed development. Among the work steps covered by Easy Breed are the planning of crosses and the subsequent creation of populations. • Extracting DNA from the tissue sample of each individual and preparing DNA samples for PCR and marker screening. The developed progenies are then evaluated and those with the desired combination of characteristics are self-pollinated to attain homozygosity. Acquaah, G. 2007. Conventional breeding practices used by plant breeders The process of conventional breeding has evolved over time, creating an effective framework that not only improves crop perfor-mance, but also supports development of foods that are safe and nu-tritious to consume. Plant breeding is the purposeful manipulation of plant species to create desirable plant types that adapt to human needs more efficiently. Such crops are known as genetically modified crops. As all traits of a plant are controlled by genes located on chromosomes, conventional plant breeding can be considered as the manipulation of the combination of chromosomes. Your email address will not be published. Plant breeding entered a new era in the 1950s and ‘60s with the advent of the Green Revolution. Following are the steps of classical breeding: Collection of variability: collection and preservation of all the different wild varieties, species and relatives of the cultivated species is a pre requisite for effective exploitation of natural genes available in the population. This 1-year degree in “Plant Breeding” is tailor-made for your interests. First, plants of a given popul… Steps in Plant Breeding * 4 points extra for more than 1600 words article. Increase yield 3. Variability forms the root of all breeding practices. With successful results, the crops are released commercially for public consumption. The first step involves … The following are the three main steps of plant breeding – Introduction of variations, selection and hybridization. The modern method of plant breeding is carried out in the following steps:-. During this time period, new chemical fertilizers and synthetic herbicides and pesticides find their way to agriculture. Variability forms the root of all breeding practices. 1. Required fields are marked *. The F1 hybrid of crosses between different genotypes is often much more vigorous than its parents. Know other methods of plant breeding in detail. There are three wass whereby unconventional methods of plant genetics can be used for applied plant breeding. Marker-assisted breeding involves following steps- • Planting the breeding populations. The EU Commission has included the revision of a Community Plant Variety Right (CPVR) regulation in its recently published IP Action Plan, in a move welcomed by plant breeding organizations.
