Genetic Improvement of Mustard

Brassica, a commercially crucial oilseed crop, is primarily cultivated in India and certain regions of Russia, Canada, Australia, and China. Due to the increasing demand for edible oils, growers are under growing pressure to increase yields to fulfil the expanding specifications of the food and paint industries. However, many biotic and abiotic stressors hinder mustard’s overall productivity. To achieve significant increases in crop yield, it is essential to enhance the ability of plants to withstand various stress factors by extensively manipulating their genetics through breeding programmes. These efforts rely on the organised gathering, protection, assessment, and utilisation of various genetic resources customised for specific challenges. The lack of germplasm or varieties that can resist crossing has necessitated using genetic engineering techniques to improve Indian mustard crops. Indian mustard has been effectively modified by introducing genes that withstand various biotic stresses. These genes include lectins, which help control aphids; chitinase and glucanase, which aid in disease management; and CODA, LEA, and ion antiporter genes, which help mitigate abiotic stresses. Induced mutagenesis is a technique that expands and exploits advantageous genetic variations to enhance crops more efficiently. It has been effectively utilised to improve the production and efficiency of various crop species. Moreover, antisense and RNAi technologies have been used to boost the seed meal and oil quality. Yellow mustard, scientifically known as Sinapis alba L., falls within the Brassicaceae family. It plays a vital role in improving genetic traits in cash crops of the Brassicaceae family, thus contributing to ongoing efforts in genetic enhancement.
