摘要

Pearl millet is regarded as the most climate-adapted and promising crop for forage production around the world. It is placed among the most important crops and comes after rice, wheat, maize, barley, and sorghum. Under harsh and dry conditions, this crop produces high biomass with high nutrition as compared to other millets and forage crops. The current chapter summarizes the progress made in efficient utilization of the available genomic resources, development of linkage maps, and mapping population involving molecular markers followed by the discussion on improvements made in breeding of disease-resistant and enhanced quality bajra. This chapter has also provided special insights for the adoption techniques like genome editing including CRISPR-Cas9, genomic selection, high-throughput phenotyping, and speed breeding in bajra that can contribute for the expedition of its genetic improvement. Availability of vast genomic resources and newer techniques has prompted the breeding toward dissection of potential forage-related traits. Significant advancements have been made in generating the whole genome sequence of bajra, which helps in providing extensive knowledge about the genetic makeup of this crop and lays down the possibilities of conducting impactful breeding. This can also help in understanding the complex nature of some quantitative traits involved in improving the quality of forage and providing better response to biotic and abiotic stresses. Along with, exploitation of high throughput genomics tools are required to be more focused on, for accelerating the breeding in bajra.
