What are the current trends in wheat breeding research?

 

Wheat is one of the most important staple food crops worldwide, providing approximately 20% of the calories consumed by humans. Wheat breeding research plays a crucial role in improving the productivity, yield, and quality of wheat varieties. Over the years, wheat breeding research has evolved, and new technologies have emerged to accelerate the breeding process and develop improved wheat varieties. In this article, we will discuss the current trends in wheat breeding research and current trends in indian wheat industry.

1.       Genomics-assisted breeding: The use of genomics in wheat breeding has become increasingly popular in recent years. It involves using genomic tools to identify desirable traits in wheat plants, and then using traditional breeding techniques to incorporate these traits into new wheat varieties. Advances in genomics technology have enabled breeders to identify desirable traits, such as disease resistance, yield potential, and nutritional quality, with greater precision and speed than ever before. This approach has led to the development of high-yielding, disease-resistant, and climate-smart wheat varieties.

2.       Marker-assisted selection: Marker-assisted selection (MAS) is a breeding technique that uses molecular markers to identify genes associated with desirable traits. These markers can be used to select plants with specific traits without waiting for the plants to grow to maturity. This technique has been successfully used in wheat breeding to develop varieties with improved yield, quality, and resistance to biotic and abiotic stresses.

3.       Hybrid wheat: Hybrid wheat breeding involves crossing two genetically diverse parents to produce offspring with improved yield potential and other desirable traits. Hybrid wheat has been shown to increase yield by 10-20% compared to conventional wheat varieties. Hybrid wheat breeding is a complex process and requires careful selection of parents and management of the hybridization process.

4.       Doubled haploids: Doubled haploids (DHs) are plants that have been developed through a process called haploid induction, which involves producing haploid plants from a single seed. DHs are genetically uniform and can be used to accelerate the breeding process by reducing the time needed for multiple generations of selfing. This technique has been used to develop new wheat varieties with improved yield, quality, and resistance to diseases.

5.       High-throughput phenotyping: High-throughput phenotyping (HTP) involves using automated systems to measure plant traits, such as growth rate, yield potential, and disease resistance, in large populations of plants. This approach allows breeders to quickly and accurately assess the performance of new wheat varieties under different environmental conditions. HTP has enabled breeders to identify traits that are difficult to measure manually and to develop wheat varieties with improved yield, quality, and resilience to climate change.

6.       Genome editing: Genome editing is a powerful new technology that allows breeders to precisely and efficiently make changes to the DNA of a plant. This technique has the potential to revolutionize wheat breeding by enabling breeders to introduce new traits into wheat plants more quickly and efficiently than traditional breeding methods. Genome editing has already been used to develop wheat varieties with improved yield, quality, and resistance to pests and diseases.

In conclusion, wheat breeding research is a rapidly evolving field, and new technologies are constantly emerging to accelerate the breeding process and develop improved wheat varieties. The current trends in wheat breeding research include genomics-assisted breeding, marker-assisted selection, hybrid wheat breeding, doubled haploids, high-throughput phenotyping, and genome editing. These techniques have enabled breeders to develop high-yielding, disease-resistant, and climate-smart wheat varieties, which are essential for ensuring food security and improving the livelihoods of farmers worldwide.
