horticulture, the branch of plant agriculture dealing with garden crops, generally fruits, vegetables, and ornamental plants. The word is derived from the Latin hortus, “garden,” and colere, “to cultivate.” As a general term, it covers all forms of garden management, but in ordinary use it refers to intensive commercial production.…

What is crop breeding?

Crop breeding largely deals with the creation, selection, and fixation of superior phenotypes for the development of improved lines or cultivars to fulfill the needs of farmers and consumers both locally and globally. However, for a long time, grain quality breeding was not a major focus of crop breeders, rather increasing yield per unit area has been the major concern. Recently, considering food and nutritional insecurity, grain nutritional improvement has become essential in major staple crops. The Harvest Plus challenge program coordinated by the International Center for Tropical Agriculture (CIAT) and the International Food Policy Research Institute (IFPRI) initiated a global platform integrated breeding program called biofortification, under the slogan of “better crops for better nutrition.” Biofortification, which can be defined as genetic enhancement of bioavailable essential micronutrients, minerals, and vitamins, in edible parts of crops for measurable impact on human health (Bouis, 2003 ), is an integrated multidisciplinary and sustainable breeding approach. As (explained) in Section 3, considerable variability in the concentration of grain micronutrients in cultivated sorghum and pearl millet varieties has been reported ( Ashok Kumar et al., 2012, 2015; Govindaraj et al., 2009, 2016a,b ). However, wider variation is found in untapped germplasm and can be used for successful genetic improvement, but difficulties in the use of such new sources in traditional breeding include linkage drag of undesirable alleles. So, like any other quantitative traits, variability for micronutrient content should be balanced by adaptation or performance. Random mating of source populations for recombination could overcome this problem, but it is a lengthy cultivar development process. In general, micronutrient traits are under multi-genic control; hence enabling genomics technologies in biofortification breeding will increase efficiency by avoiding linkage drag and speed up cultivar development.

What is the introduction of crop breeding?

Introduction – novel genes for the next generation of improved crops. Crop breeding as a science-based discipline has existed for more than 100 years. It is therefore quite remarkable that the basic breeding techniques used to select and combine favourable agronomic traits have hardly changed at all.

How does crop breeding affect oil?

Crop breeding has achieved numerous modifications of the fatty acid profile of oil in many species, mainly through the incorporation of genes with large effects (for a review see Velasco and Fernández-Martínez, 2002 ). The effect of the environment on these genotypes is relatively small (e.g. up to 6.9% for high-oleic sunflower; Izquierdo and Aguirrezábal, 2008 ), but it can still be a concern, especially with strict market standards. The stability of improved fatty acid compositions and the achievement of a desired quality under specific environments are important breeding objectives.

How to achieve targeted genetic gain?

Targeted genetic gain can be achieved at a faster rate by shortening the breeding cycle or generation time rather than selection intensity and heritability, which are highly trait and environment dependent. Shortening the breeding cycle or generation time can be achieved by adopting SB.

How does genome editing help in crop breeding?

Moreover, such techniques have the potential to decrease regulatory burdens, at least in the United States. The numerous benefits associated with genome-editing technology, without doubt, will change the face of basic plant research and crop breeding. Genome editing enables discovery of gene function through targeted mutagenesis, leading to trait discovery via the formation of new gene variants. It also simplifies and expedites the introduction of novel traits and maintenance of complex traits through gene stacking. For producers, this means more products of higher quality with fewer costs, less labor, as well as new markets and opportunities. For consumers, this new technology will mean the abundant availability of more nutritious food at lower cost.

What are the traits of agronomy?

In terms of agronomy, the traits which belong to this latter category are yield, nutrient uptake, durable resistance to pathogens and pests, tolerance to abiotic stresses (e.g. drought, heat), taste, aesthetics, processing qualities, and nutritional value to name but a few.

Is rice genetic engineering?

However, rice genetic engineering by itself face s several constrains that limit application of genome-editing technologies. For example, most genome-editing studies were performed only with a limited number of transformable japonica rice varieties. It is still technically challenging to perform genetic engineering in the majority of rice cultivars, especially indica rice that remains recalcitrant to tissue culture and regeneration. Difficulty in rice protoplast culture and regeneration precludes the application of preassembled ribonucleoprotein of CRISPR/Cas or recombinant TALEN proteins for genome editing—processes that do not involve DNA in mutagenesis. Another issue is the uncertainty of regulatory rulings by governments in regard to genome edited rice. The stringency of such regulation will affect the application of genome-editing technologies in rice breeding and commercialization of TALEN- and CRISPR-modified rice. Overcoming these limitations will be a key to allowing full realization of the great potential of genome-editing technologies to meet the increasing challenge for achieving food security posed by the ever increasing world population.

Cross-breeding: individuals of different breeds or lines are used to mate. Pure breeding: the same breed or lines are used to mate. Inbreeding: two close relatives mate.

Why is animal production increasing?

To fulfil this growing demand, global animal production should increase while taking into account issues of environmental sustainability, food safety, and animal welfare. The breeding sector can contribute to finding solutions that are cost and resource efficient, diminish or eliminate environmental pressure, are adaptive to climate change, are beneficial for animal health and welfare, improve food quality and safety, and that meet the needs of citizens, both today and in the future.
