Modern Era of Rice (Oryza Sativa L.) Genomics for Precise Genomics-Assisted Drought Breeding| Biomed Grid

Rice (Oryza sativa L.) is an important food crop and requires larger amount of water throughout its life cycle as compared to other crops. Hence, water related stress cause severe threat to rice production. Drought is a major challenge limiting rice production. The screening of rice germplasm under drought and its characterization at the morphological, genetic, and molecular levels revealed the existence of genetic variation for drought tolerance within the rice gene pool. The improvements made in managed drought screening and selection for grain yield under drought have significantly contributed to progress in drought breeding programs. The availability of rice genome sequence information, genome-wide molecular markers, and low-cost genotyping platforms now makes it. Drought possible to routinely apply marker-assisted breeding approaches to improve grain yield under drought. Grain yield Grain yield QTLs with a large and consistent effect under drought have been identified and successfully Genetics pyramided in popular rice mega-varieties. The transgenic approach Proteomics is successful in generating drought tolerance in rice under controlled conditions, but field-level testing is necessary. Genomics-assisted drought breeding approaches hold great promise, but a well-planned integration Allele mining with standardized phenotyping is highly essential to exploit their full potential.
